Installing the GPU Module

This chapter contains the following topics:

Installing and Removing the GPU Module

The front mezzanine module installs into the front mezzanine slot of Cisco UCS X-Series compute nodes.

Required Equipment

Cisco provides a kit (UCSX-X10C-GPUFM) for installing the Cisco UCS X10c front mezzanine GPU module. The kit contains the following:

  • Required GPU cables

  • The front mezzanine cage including:

    • The storage cage which supports a maximum of two U.2 drives

    • The GPU cage which supports a maximum of two Cisco T4 GPUs (UCSX-GPU-T4-MEZZ).


    Note

    If you order the Cisco UCS X10c front mezzanine GPU module with one GPU, the unused GPU slot is pre-populated with a filler module. You can purchase additional filler modules from Cisco

To provide flexibility for your deployment, the U.2 drives and GPUs are orderable separately. However, if you order the Cisco UCS X10c front mezzanine GPU module with one GPU, the unused GPU slot is pre-populated with a filler module. You can purchase additional filler modules from Cisco.

The following additional equipment, which is not provided by Cisco, is required to install or remove the GPU module.

  • T8 Torx screwdriver

  • #2 Phillips screwdriver

  • Torque wrench

Removing the Front Mezzanine GPU Module

To remove an existing front mezzanine module, you will remove screws on the side of the compute node's sheet metal tray and on the node's motherboard.


Caution

Do not operate the compute node without a front mezzanine module installed.

Use the following procedure to remove an existing front mezzanine module.

Before you begin

Review Cabling Considerations for important information before beginning this task.

The compute node cables must be disconnected, and the compute node must be removed from the chassis to perform this task.

Procedure

Step 1

Remove the top cover of the compute node.

Step 2

Remove the screws.

  1. Using a T8 Torx screwdriver, remove the four T8 Flathead screws, two screws per side.

  2. Using a #2 Phillips screwdriver, loosen the two #2 Phillips captive screws at the rear of the front mezzanine module.

Step 3

Grasp the front mezzanine module at the middle of the top front edge and lift the front mezzanine module straight up to remove it from the compute node.

What to do next

Connect the front mezzanine GPU module to the compute node. Installing the Front Mezzanine GPU Module

Installing the Front Mezzanine GPU Module

To install the front mezzanine GPU module, you will insert screws on the side of the compute node's sheet metal tray and on the node's motherboard.

Use the following task to install the X10c front mezzanine GPU module.

Before you begin

Review Cabling Considerations for important information before beginning this task.

Procedure

Step 1

Holding the front mezzanine module by the center of the top edge, keep the module level, and lower it down onto the compute node (1).

Step 2

Align the rear captive screws with the threaded standoffs (2).

Note 

The motherboard has guide pins that assist with installing the module onto the compute node. Use these guide pins while installing the module.

Step 3

Press down evenly on the module to seat the module's connectors into their sockets on the motherboard.

Step 4

Using a Phillips screwdriver, tighten the two rear captive screws to 5 in-lb of torque.

Step 5

Using a T8 Torx driver, tighten the four T8 flat head screws on the sides of the compute node (2 screws per side) to secure the module to the compute node.

Step 6

Replace the compute node top cover and reinstall the compute node into the chassis.

Front Mezzanine GPU Module Configuration

The Cisco UCS X10c front mezzanine GPU module can be configured and managed using the Cisco Intersight management platform in Intersight Managed Mode (Cisco Intersight Managed Mode). For details, see the Cisco Intersight Managed Mode Configuration Guide, which is available at the following URL: Cisco Intersight Managed Mode Configuration Guide
