Installing and Removing a Compute Node Blank

The UCS X9508 supports up to 8 compute nodes, with a minimum configuration of one compute node. If compute node slots do not contain a compute node, you must install a compute node blank.

Use these procedures to replace a compute node blank:

Installing a Compute Node Blank
Removing a Compute Node Blank

Removing a Compute Node Blank

Do not operate the server chassis with an empty compute node slot. Fill any empty compute node slots with either a blank (UCSX-9508-FSBK) or a compute node.

Use this task to remove a compute node blank.

Procedure

Step1

Grasp the compute node by the finger holds.

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (16)

Step2

Pull the compute node blank towards you until it is completely removed from the chassis.

Notice that the module blank has indicators that show how to orient the blank. You will use this information when you install a blank.

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (17)

What to do next

Choose the appropriate option:

Installing a Compute Node
Installing a Compute Node Blank

Installing a Compute Node Blank

If you remove a compute node, and you will not be installing another compute node, you must install a compute node blank. Do not operate the server with an empty compute node slot. The minimum configuration is 1 installed compute node, so in this configuration you need 7 module blanks installed.

Compute node blanks are interchangeable within the same chassis or other chassis.

Use this task to install a compute node blank

Procedure

Step1

Grasp the blank by the finger holds.

Step2

Hold the module blank vertically and align the module blank with the slot.

Note

The module blank has an arrow and the word UP that show how to orient the blank. Also, if you attempt to install the blank with the wrong orientation, the module does not sit flush with the front of the chassis.

Step3

Keeping the compute node blank vertical, slide it into the slot until the blank is flush with the face of the chassis.

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (19)

Installing and Removing a Compute Node

The Cisco UCS X9508 server chassis supports full-height compute nodes. For details, see the Installation and Service Note for your compute nodes. See http://www.cisco.com/en/US/products/ps10280/prod_installation_guides_list.html

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (20)

Caution

When working with the compute nodes, handle them carefully to avoid damage to the modules, connectors, and pins.

Installing a Compute Node

Use this task to install a compute node in an empty slot.

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (21)

Caution

When working with the compute nodes, handle them carefully to avoid damage to the modules, connectors, and pins! Make sure that the modules are level during insertion and slide them into the chassis slowly.

Before you begin

If there is a module blank in the slot where you want to install a compute node, remove the blank now. See Removing a Compute Node Blank.

Compute nodes are shipped with the ejector handles closed and locked. Each compute node has a release button in the center of the node that releases the ejectors from the locked position.

Procedure

Step1

Press the release button at the center of the compute node faceplate to release the ejectors.

Caution

The ejectors have a hook at the pivoting end that attaches to the compute node. While you are inserting the compute node, keep the ejectors open as shown in the following illustration. If the ejectors are not open, the hook can be an obstruction while sliding the node into the chassis.

Step2

Holding the compute node vertical, align it with the empty module bay in the chassis.

The compute node is correctly aligned when the server top cover is pointing to the left.

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (22)

Step3

Keeping the compute node vertical, slowly slide it into the chassis.

As the compute node is almost completely installed, you might feel some resistance. This resistance is normal. It occurs because the connectors at the rear of the compute node contacts the connector on the inside of the chassis.

Caution

Make sure to apply even pressure when sliding the module into the chassis. Do not push down or pull up on the module handles, and do not apply more force to one ejector handle than the other.

Step4

When the compute node is almost completely installed, grasp the ejector handles and arc them toward each other.

This step seats the compute node into the connector. The compute node should power up.

Caution

Make sure to apply even pressure when closing the module ejector handles! Do not push down or pull up on the module handles, and do not apply more force to one ejector handle than the other.

Step5

Push the ejectors until they are parallel with the face of the compute node.

When the compute node is completely installed, the retention latches at the end of each handle click into place.

Removing a Compute Node

Use this task to remove a compute node.

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (23)

Caution

When working with the compute nodes, handle them carefully to avoid damage to the modules, connectors, and pins! Make sure that the modules are level during removal and slide them out of the chassis slowly.

Before you begin

Do not operate the server with an empty compute node slot. If you will not be installing a compute node in an empty slot, install a compute node blank to cover the empty slot.

Procedure

Step1

Press the release button at the center of the compute node faceplate to disengage the ejector handles.

Step2

Grasp the ejector handles and pull them outward so that they arc vertically away from each other.

While moving the compute node handles, you might feel some resistance. This resistance is normal. It occurs because the connectors at the rear of the compute node are unseating from the corresponding sockets in the chassis.

Also, when the compute node disconnects from the midplane, the server powers off.

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (24)

Step3

Grasp the compute node handles and slide the compute node partially out of the chassis.

Make sure to keep the compute node vertical while removing it.

Caution

Make sure to apply even pressure when sliding the module out of the chassis. Do not push down or pull up on the module handles, and do not apply more force to one ejector handle than the other.

Step4

Place your other hand underneath the compute node to support it and slide the compute node completely out of the chassis.

What to do next

Fill the empty compute node slot. Go to the appropriate option:

Installing a Compute Node
Installing a Compute Node Blank

Installing and Removing Power Supplies

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (25)

Note

The power supplies are keyed to work only with their respective power expansion module (PEM), depending on the chassis version.

When in installing and removing power supplies, make sure that the minimum number of power supplies are active before replacing the other PSUs. For example, in a 3+3 grid power configuration, at least 3 PSUs must be active before replacing the other 3 units one at a time per grid.

The PSUs are installed vertically along the side of the chassis.

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (26)

PSU Population Rules

When you install PSUs, they must be equally divided into top and bottom PSU slots to ensure redundancy. See the following PSU population rules.

For 2 PSUs: Install a PSU in slots 1 and 4. This is the minimum supported config.
For 3 PSUs: Install a PSU in slots 1, 2, and 4.
For 4 PSUs: Install a PSU in slots 1, 2, 4, and 5.
For 5 PSUs: Install a PSU in slots 1, 2, 3, 4, and 5.
For 6 PSUs: Install a PSU in all slots.

Any slots that do not contain a PSU must be covered by a PSU blank.

Installing a Power Supply

The Cisco UCS X9508 AC PSU does not have a discrete power switch. It powers on immediately when it is successfully connected to the power midplane. When installing a PSU, you must comply with the PSU population rules. See PSU Population Rules.

PSUs are hot swappable with a minimum population of two in the chassis to provide redundancy. PSUs are interchangeable and none are reserved through the management software.

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (27)

Caution

When connecting the chassis to facility power, make sure not to overload the capacity of a PDU or power strip. For example, do not connect all PSUs to one PDU or power strip that is not capable of carrying the total power draw of the chassis.

Use the following procedure to install the PSUs.

Procedure

Step1

Grasp the PSU with one hand.

Step2

Use your other hand to support the PSU, and holding it level, orient it with the PSU bay.

The PSU is correctly oriented when the latch is facing you and parallel with the right side of the PSU bay.

Step3

Holding the PSU level, slide it into the PSU bay.

Note

When the PSU is almost all the way in, you will feel some resistance, which is normal. The resistance is the connector at the rear of the PSU meeting the power socket inside the chassis.

The PSU will power on when you have successfully seated it in its socket.

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (28)

Step4

For each PSU that must be installed, repeat these steps.

Step5

Verify the power supplies are operating by checking the power supply LEDs. See LED Locations and Interpreting LEDs.

Note

Both grids in a power redundant system should have the same number of power supplies. If your system is configured for grid power (N+N redundancy), slots 1, 2 and 3 are assigned to grid 1, and slots 4, 5, and 6 are assigned to grid 2. If fewer than six power supplies (PS) are configured in grid redundant mode, they should be equally distributed between the grid 1 and grid 2 slots.

Removing a Power Supply

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (29)

Caution

If you are using the Cisco UCS X9508 server chassis with one power supply, which is a non-redundant power configuration. Removing the power supply will cause the compute nodes and chassis to shut down. If you are using more than two power supplies, and you remove one of them (the minimum supported power configuration is 3 PSUs), the servers continue to operate as long as the other power supplies are sufficient to meet the power requirements of the number of compute nodes in the chassis.

The PSU has a locking latch that secures the PSU in the chassis. You must unlock the latch to remove the PSU. You can expect some resistance as the PSU slides out due to its weight.

Procedure

Step1	Place your thumb on the PSU locking latch at the vertical fingerhold on the right side of the blank's faceplate and allow your other fingers to rest along the side of the chassis.
Step2	Press the latch to unlock the PSU, then pull until it disengages from the power socket inside the chassis. You will feel some resistance initially as the connector at the rear of the PSU unseats from the power socket inside the chassis.
Step3	As you slide the PSU out of the chassis, use your other hand to support the PSU.
Step4	Install a blank power supply filler panel if the power supply bay is to remain empty.

What to do next

Choose the appropriate option:

If you will be reinstalling a PSU, go to Installing a Power Supply
If you will be installing a PSU blank, go to Installing a PSU Blank.

Replacing a PSU Blank

PSU blanks (UCSX-9508-PSUBK) are interchangeable, but if you will be operating the server chassis without a PSU, the empty bay must be covered with a PSU blank. Replace a PSU blank when you remove a PSU but will not install another PSU in that PSU bay, or when you remove a PSU blank and need to cover the empty PSU bay.

Removing a PSU Blank
Installing a PSU Blank

Removing a PSU Blank

Use this procedure to remove a PSU blank.

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (32)

Note

The PSU blank is a small plastic piece. It does not have a locking latch, so it slides out easily.

Procedure

Step1

Place your thumb behind the vertical fingerhold on the right side of the blank's faceplate and allow your other fingers to rest along the side of the chassis.

Step2

Using your thumb, grasp the PSU blank by the vertical fingerhold and pull the PSU blank straight towards you.

The PSU should easily slide out of the chassis.

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (34)

What to do next

Choose the appropriate option:

If you are installing a PSU, go to Installing a Power Supply.
If you are installing a PSU blank, go to Installing a PSU Blank.

Installing a PSU Blank

The minimum supported power configuration for the UCS X9508 server chassis is three PSUs. If you will be operating the server chassis with an empty PSU bay, it must be covered with a PSU blank (UCSX-9508-PSUBK).

Use this procedure to install a PSU blank.

Procedure

Step1

Grasp the PSU blank by the vertical finger hold on the right side of the blank's face.

Step2

Align the PSU blank so that the word UP is facing up, and the handle is parallel to the right side of the PSU bay.

Step3

Insert the PSU blank until its faceplate is flush with the front of the server chassis.

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (35)

Replacing the PSU Keying Bracket

The PSU Keying bracket is attached to the right exterior side of the chassis. The bracket ensures that only the correct type of PSU can be installed, and that the PSU is inserted in correct orientation in the chassis.

Use the following procedures to replace the PSU Keying bracket:

Removing the PSU Keying Bracket
Installing the PSU Keying Bracket

Removing the PSU Keying Bracket

Use this procedure to remove the PSU Keying bracket.

Before you begin

The chassis must be completely removed from the rack to provide access to the exterior of the chassis where the PSU Keying bracket will be installed.

When the chassis is removed from the rack, make sure that you place the chassis on an ESD-safe workspace, for example, a rubberized mat.

Procedure

Step1

If you have not already removed the chassis from the rack, do so now.

Go to Removing the Chassis from a Rack.

Caution

Make sure to follow all safety requirements while uninstalling the chassis, including using a device, such as a mechanical lift, to bear the weight of the chassis.

Step2

With the chassis in an ESD-safe work area, locate the PSU Keying bracket on the right exterior side of the chassis.

Step3

Using a T10 screwdriver, remove the six screws that attach the bracket to the chassis.

Step4

Grasp the PSU keying bracket and detach it from the chassis.

Step5

Keep the screws and bracket.

What to do next

Installing the PSU Keying Bracket.

Installing the PSU Keying Bracket

Use this task to install a PSU Keying bracket (UCSX-9508-KEY-AC=).

Procedure

Step1	With the chassis on an ESD-safe work area, grasp the new PSU Keying Bracket, and align it with right exterior side of the chassis.
Step2	Place the bracket against the side of the chassis, aligning the screwholes in the bracket with the screwholes in the chassis.
Step3	Insert the 6 screws into the screwholes.
Step4	Using a T10 screwdriver, secure the bracket to the chassis by tightening each screw to snug. If you have access to a torque wrench, tighten the screws to 6 in-lb.
Step5	Reinstall the chassis: Insert the chassis into the rack. Reinstall the chassis components and reconnect any cables that were disconnected. For additional info, see Installing the Chassis.

Replacing the Power Entry Modules (PEMs)

The Cisco UCS X9508 chassis contains two power entry modules (PEMs). Each PEM is a grouping of 3 IEC 320 compatible C20 power inlets. One PEM supports PSUs 1 through 3, and one PEM supports PSUs 4 through 6. Each PEM is field replaceable.

Use the following procedures to replace the PEMs:

Installing the Power Entry Modules
Removing the Power Entry Modules

Installing the Power Entry Modules

Use this procedure to install a PEM.

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (38)

Note

The following task shows installing both PEMs. If you are installing only one PEM, you will need to tighten only the PEM screw for the replaced PEM, not both screws as shown in the illustrations.

Before you begin

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (39)

DANGER

Follow all electrical safety precautions when working with facility power. Failure to do so can result in damage to the equipment or pose a risk of injury or death to personnel.

Procedure

Step1	Grasp the PEM and orient it correctly. The PEM is keyed so that you can insert it only one way.
Step2	Holding the PEM level, slide it into the PEM slot. You might feel some resistance as the connector on the rear of the PEM meets the connector on the interior of the chassis.
Step3	Using a T10 screwdriver, tighten the captive screws which are easily identifiable because they are next to the electrical ground icons on the chassis walls. Tighten the exterior captive screws. Tighten the interior captive screws.
Step4	Reinstall the IFMs and expansion modules. Go to Installing an Intelligent Fabric Module. Go to Installing a UCS X-Fabric Module Blank.
Step5	Reconnect all power cables. The chassis automatically powers on when it receives inlet power.

Removing the Power Entry Modules

PEMs support inlet power to the chassis from the facility. It is a best practice to remove all power from the system when replacing a PEM.

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (43)

DANGER

Follow all electrical safety precautions when working with facility power. Failure to do so can result in damage to equipment or pose a risk of injury or death to personnel.

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (44)

Note

The following task shows removing both PEMs. If you are removing only one PEM, you will need to loosen only the PEM screw for the replaced PEM, not both screws as shown in the illustrations.

Before you begin

The power entry modules (PEMs) are connected to facility power, so you must disconnect facility power from the PEM that you will be removing.

Procedure

Step1	Power down all compute nodes.
Step2	Remove any power cables that are attached to the PEM.
Step3	Remove the IFMs and expansion modules. Go to Removing an Intelligent Fabric Module. Go to Removing a UCS X-Fabric Module Blank.
Step4	Using a T10 screwdriver, loosen the captive screws that attach the PEM to the chassis. The captive screws are easily identifiable because they are next to the electrical ground icons on the chassis walls. Loosen the exterior captive screws. Loosen the interior captive screws.
Step5	Grasp the PEM and slide it out of the chassis. When you remove a PEM, you must replace it with another one. Do not operate the system with an empty PEM slot.

What to do next

Install a PEM. Go to Installing the Power Entry Modules.

Installing and Removing a Fan Module

You can hot swap a fan module (UCSX-9508-FAN) without causing an electrical hazard or damage to the system. However, you can only remove one fan module while the system is operating. Removing more than one fan module could cause overheating.

Fan Module Replacement Consideration

While a fan module is absent from the chassis, the pair of compute nodes physically associated with that fan may be throttled to prevent thermal overload. After the fan module is replaced in the chassis, throttling is removed and the associated blades resume normal operation.

To minimize the impact to system performance, do not remove a fan module until a replacement fan module is available. Leaving the fan module out of the chassis for longer durations of time will result in extreme power throttling of the associated compute nodes, but the nodes will not shutdown.

The following table shows the mapping of fan modules to their associated compute nodes.


Fan Module	Compute Node Slots
1	7, 8
2	5, 6
3	3, 4
4	1, 2

Installing a Fan Module

Procedure

Step1

Hold the fan module with the handle at the bottom and place your other hand underneath the fan module to support it.

Step2

Align the fan with the fan bay in the rear of the chassis.

Cisco UCS X9508 Server Chassis Installation Guide - Installing and Removing Components [Cisco UCS X9508 Chassis] (48)

Step3

Slide the fan into the chassis until it is flush with the face of the chassis.

Note

Make sure that the latch on the handle is engaged with the chassis.

When the fan module is almost completely installed, you might feel some resistance. The resistance is normal, and it occurs when the connector at the rear of the fan contacts the corresponding socket inside the chassis.
