grounding this device. The chassis is concurrently grounded through each of the PSUs. Only con-
nect the PSU cords to properly grounded outlets. Do not rely on the PSU grounds. It is absolutely
necessary to connect the grounding post. Make sure the connections are solid and permanent. If
you choose to not use the ground screw, make sure that the rack is properly grounded and that
there is a valid ground connection between the chassis of the switch and the rack.

FRU Insertion and Extraction (Hot-Swappable)

Before starting any procedure on the switch system, put an ESD prevention wrist strap on your
wrist and connect to the chassis.
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.
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 manage-
ment 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 modules
• Management modules
