Maintaining the Server

This chapter contains the following topics:

Service Considerations

Be aware of the following when servicing the server:


Important

Be careful with your hands and fingers whenever you handle the server, trays, and components! Narrow vertical or horizontal spaces in situations such as, but not limited to, moving the server into or out of the shipping container or equipment rack can cause pinch hazards for your hands and fingers.


Warning

The fully configured server weighs approximately 265 lbs. (120 kg)! Never attempt to lift the server by yourself! Instead, use a lift, scissors jack, or some other device to lift and bear the weight of the server while you are installing or servicing it. If you must lift or handle the server without mechanical assistance, use two or more people to lift and handle server. Always use safe lifting practices when lifting or moving the server.


Note

When handling chassis components, wear an ESD strap and handle components, modules, and trays by the edges, or by designated handles when present.

The server is designed as a modular system with subsystems for compute, cooling, and so on. Subsystems are generally arranged in trays, which are field replaceable units (FRUs). However, some components in a subsystem or tray are not individually field-replaceable. The following components are not field replaceable.

  • Mainboard/Motherboard

  • Power distribution board

  • Mid-plane board

  • HIB host interface Board

  • FIO board

  • CEM 8X BB board

  • Left CEM (LCEM) Riser

  • Right CEM (RCEM) Riser

  • Fan extension board

  • Fan interposer board

  • CPUs

  • DIMMs

  • M.2 drives on motherboard

Alignment Features

The server has different alignment features that facilitate removing and installing components safely and easily. Being aware of these features will help you replace the field-serviceable components in the server.

CPU Tray Top Cover Alignment Features

The CPU Tray has grooves and guide pins to help install the top cover of the CPU Tray.

Inner Cover Alignment Features

The inner cover has grooves and catch pins to help align it.

Riser Cage Alignment Features

The interior of the riser cages have notches that meet a tab on the faceplate of the cards that install into them.

Replacing NVIDIA BlueField3 3220 DPUs

The server's north-south traffic is supported by up to two NVIDIA BlueField3 3220 DPUs, which are field-serviceable.

The cards can be installed in slots 11 through 16 on the CPU Tray. Slots are labelled for easy slot identification.

To replace BlueField3 cards, see the following topics.

BlueField3 3220 DPU Guidelines and Restrictions

Before installing or removing an NVIDIA Bluefield3 3220 DPU (BlueField card), be aware of the following guidelines and restrictions:

  • Alignment features are present for the BlueField cards. Before attempting the installation or replacement procedure, familiarize yourself with the alignment feature for the riser cages. See Alignment Features.

  • Screws for internal components are small and can shear. Do not overtighten the screws or you risk breaking them! When installing screws, tighten them to snug only.

  • The BlueField cards are installed in riser cages on the CPU Tray. The CPU Tray is heavy and requires at least two people to lift it. When removing, installing, or otherwise handling the CPU Tray, you must have at least two people. As a best practice, use a server lift or other mechanical means to bear the weight of the CPU Tray.

  • The server supports up to two BlueField cards. Cards mount into riser cages and can be installed in any slot in the cage. However, for best practices, follow these guidelines.

    • When installing one card in the server, use slot 13, which is the middle slot on the right riser cage as you face the server rear panel.

    • When installing both cards in the server, make sure to install one card in each of the riser cages.

      • Use slot 13, which is the middle slot on the right riser cage as you face the server's rear panel.

      • Use slot 14, which is the middle slot on the left riser cage as you face the server's rear panel.

    • Even though all slots in each cage are usable, the middle slot (13 and 14) of each riser cage is easily accessible whereas the top and bottom slots of each riser cage can experience partial obstruction due to cables.

  • Due to the location of internal sheetmetal walls, if you are installing or replacing the BlueField card in the right riser cage, you will need to remove the east-west GPU (Slot 1) to gain access to that riser cage.

Accessing the BlueField3 Cards
