System Management
6.2.1.1.4
You can use an external remote power supply (RPS) as the third power supply for
the 7210 SAS-Sx 1/10GE copper variants. With an RPS, a common external power
supply is used as the redundant power supply for a stack of 7210 SAS-Sx 1/10GE
nodes. This provides a cost-effective option to supply power to a stack of units.
Additional configuration is not required to use an RPS on the node. The presence of
an RPS is detected automatically, and the show>chassis>power-supply command
displays information about the RPS and its status.
For information about installing RPS, refer to the 7210 SAS-Sx/SAS-S RPS Chassis
Installation Guide.
6.2.1.1.5
All service-related statistics are kept during a switchover. Services, SDPs, and SAPs
will remain up with a minimum loss of forwarded traffic during a CFM/CPM
switchover.
