FRU Insertion and Extraction

CS7510 324-Port EDR InfiniBand Switch-IB™ Series Switch Platform Hardware User Manual

Before starting any procedure on the switch system, put an ESD preventive wrist strap on your wrist and connect to the chassis.

Note

Do not mix replacement parts based on different generations of chip. All replacement modules must be consistent with the chassis family and switch chip generation.

Warning

When hot-swapping any of the units, it is necessary to wait 1 minute after removing the defective part before inserting the new part. This is necessary so that the management module will start a new cycle checking through the leafs and spines for the FW versions.

This switch platform supports hot swap capabilities for the following parts:

  • Power supply units

  • Leaf modules

  • Spine modules

  • Leaf fan modules

  • Spine fan modulesA new system would have the PSU already installed so there

  • Management modules

For information on the ordering part numbers for these field replaceable units (FRUs), see Replacement Parts Ordering Numbers.

The power supplies deliver 2500W at 48VDC. The input to each of these power supplies requires 12A current in order to output 2500W.

For N+N configuration up to half of the PSUs can go down and the system will continue to run.

The power required to run the switch system is equally divided between all of the working PSUs.

Extracting and Inserting the PSU

With all of the N+N 2500W power supplies installed, the system is in N +N redundant configuration, half of the PSUs may be extracted without bringing down the system.

To extract a PSU:

  1. Determine which AC connector on the connector side of the chassis corresponds to the defective PSU.

  2. Remove the power cord from the PSU’s inlet. Note which power cord it is according to the AC numbering.

  4. Grasping the handle with one hand, push the black latch release while pulling the handle outward. As the PSU unseats, the PSU status indicators will turn off.

  5. Remove the PSU.

To insert a power supply unit:

  1. Make sure the mating connector of the new unit is free of any dirt and/or obstacles.

  2. Insert the PSU by sliding it into the opening until a slight resistance is felt.

  3. Continue pressing the PSU until it seats completely. The latch will snap into place confirming the proper installation.

  4. Insert the power cord into the supply connector on the other side of the chassis.

  5. Replace the cover over the PSUs.

    Important

    The green indicators should light. If not, extract the PSU and re-insert it again.

Important

When hot-swapping any of the units, it is necessary to wait 1 minute after removing the defective part before inserting the new part. This is necessary so that the management module will start a new cycle checking through the leafs and spines for the FW versions.

Leaf module slots are numbered from top to bottom from L1 to L9 on both sides of the chassis.

Extracting a Leaf Module

Each leaf module has 2 ejector handles that locks the module in place and serve as a lever for seating or extracting (see the Releasing Leaf Ejector Handles figure below).

  1. Run the shut down command “no power enable <module>”. For example to shut down leaf 16, run the command:

    switch [master] (config) # no power enable L16

  2. Disconnect all cables connected to the leaf.

  3. Push the ejector handles in the direction of the red arrows in the figure below and pull them outwards to unlock the ejectors from the chassis.

    image2023-9-11_18-11-7.png

  4. Open the ejectors until it is 45 degrees from the leaf.

  5. Pull out the module halfway through the guiding rails using the ejector handles.

  6. Re-lock the ejector handles.

  7. Hold the body of the leaf on both sides and remove it from the chassis.

    Important

    The module is short, therefore do not let go of it while sliding it out.

Inserting a Leaf Module

Important

When hot-swapping any of the units, it is necessary to wait 1 minute after removing the defective part before inserting the new part. This is necessary so that the management module will start a new cycle checking through the leafs and spines for the FW versions.

To insert the leaf module:

  1. Check for foreign objects in or mechanical damage to the chassis leaf slots.

  2. Check leaf mechanics for any noticeable damage.

  3. Check back signal connectors’ integrity. Look for any broken signal dividers or any deviations from the pass criterion shown below.

    image2023-9-11_18-11-37.png

  5. Start with the ejector handles fully open; that is, at 45 degrees to the front panel of the leaf.

  6. Holding the leaf by its sides, carefully set the leaf module halfway into the chassis.

  7. Applying equal pressure on both sides of the leaf module, and using only the ejector handles, slowly slide the module into the chassis until the ejector handles reach the vertical bar.

    Important

    Do not apply excessive force to slide in the leaf module. If you feel resistance, remove the leaf module and double check both the chassis and leaf for any damage.

  8. Catch the ejector handle hooks onto the vertical bar of the chassis and push the ejector handles shut.

  9. Lock the ejector handles onto the module.

Note

Do NOT mix replacement parts based on different generations of chip. All replacement modules must be consistent with the chassis family and switch chip generation.

Important

When hot swapping any of the units, it is necessary to wait 1 minute after removing the defective part before inserting the new part. This is necessary so that the management module will start a new cycle checking through the leafs and spines for the FW versions.

Each spine has a pair of ejectors that lock the module in place and serve as levers for seating or extracting (see Releasing Spine Ejector Handles).

Management module 1 is connected to spine module 1, and management module 2 is connected to spine module 2. All of the spine modules can be hot-swapped when these two management modules are installed and working.

Important

When a slave management module is not installed or not working, the spine module connected to the master management module cannot be hot-swapped.

Spine module slots are numbered from top to bottom from S1 to S6 on both sides of the chassis.

Extracting a Spine Module

Important

When a slave management module is not installed or not working, hot-swapping the spine module connected to the master management module will cause the chassis to crash.

Note

Neither the CLI nor the GUI management tools will allow you to shut down spine #1 or spine #2, as the management modules are connected to the chassis components through these spines.

Extracting Spine Module #1 or #2

Spine module #1 is connected to management module #1 and spine module #2 is connected to management module #2.

Management Module Numbering

image2023-9-11_18-12-19.png

Important

Removing spine #1 causes management module #1 to reset. Removing spine #2 causes management module #2 to reset.

Important

Warning: If the spine you want to hot swap is connected to the master management module the management module will reboot when you take out the spine.

Important

Do not extract spine 1 or 2 if only one management module is connected! Doing so will cause the switch system to hang which will lead to traffic loss.

If you need to hot swap spine #1 or spine #2:

  1. Make sure that two management modules are connected to the switch system. See the Management Module Numbering figure above.

  2. Extract the spine module according to the procedure in "Extracting Spine Modules Except #1 or #2" below starting with Step 2 (without running the shutdown command).

    Important

    Traffic loss and errors in the log may be experienced momentarily.

Extracting Spine Modules Except #1 or #2

  1. Run the shut down command no power enable <module>. For example to shut down spine 06 run the command below.

    switch [master] (config) # no power enable S06

  2. Push the ejector handles in the direction of the red arrows in the figure below and pull them outwards to unlock the ejectors from the chassis.
