To insert a PSU:
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.

Leaf Boards
The leaf boards are numbered from top to bottom, with corresponding numbers dis-
played to the outside of the leafs vertically along the side panel.
The green indicators should light. If not, extract the PSU and re-insert it again.
Do NOT mix replacement parts based on different generations of chip.
Do not install InfiniScale IV based replacement parts within a SwitchX® based chas-
sis and vice versa. All Replacement modules must be consistent with the Chassis fam-
ily 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.
