Line Card Considerations

Caution – The thermal management of the switch chassis is compromised when a
line card slot is vacant. You must install a filler panel or replacement line card
immediately after removing one.
Line cards are heavy and must be installed by two people. This method ensures that
proper alignment can be achieved before the line card retainers are locked. Improper
alignment can bend midplane connector pins.
Line cards use high-density iTRAC connectors that interface with the midplane pins.
If these connectors are damaged, the pins of the midplane connector can also be
damaged upon line card insertion.
Equally important, the line cards have iPASS connectors for attaching IB cables. If
one of these connectors is damaged, then 3 nodes of the line card cannot be used.
You must inspect the front and back line card connectors, and retainers before
installing the line card into the switch chassis.
