6.1 Fabric Card Considerations
Caution – The thermal management of the switch chassis is compromised when a
fabric card slot is vacant. You must install a filler panel or replacement fabric card
immediately after removing one.
Fabric 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 fabric card insertion.
You must inspect the fabric card connectors, fans, and retainers before installing the
fabric card into the switch chassis.
