1.10.2.1 Extracting a Leaf Board
Each leaf board has a ejector handle that locks the board in place and serves as a lever for
seating or extracting (see Figure 36).
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.
