7.1Line 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 use high-density iTRAC connectors that interface with the midplane pins. If these connectors are damaged, the pins of the midplane connector are also 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 24 nodes of the line card cannot be used.
