7.2 Active Maintenance Flow
This section explains the replacement workflows in the active state for the following FRUs mounted on the crossbar box.
- XSCF unit
- XSCF BB control cable
- XSCF DUAL control cable
- Power supply unit
- Fan unit
- Dedicated power distribution unit mounted on the rack for expanded connection
| Note - Maintenance is not available in the active/cold state for FRUs mounted on the crossbar box. In the active state, only hot maintenance is enabled. |
| Note - Active/Hot maintenance is enabled for an XSCF BB control cable used in the following connection. - Cable connecting crossbar boxes to each other |
| Note - Active/Cold maintenance is enabled for an XSCF BB control cable used in the following connection. - Cable connecting each chassis to the crossbar box in a configuration where one physical partition consists of chassis with two or more BBs |
