Configuration Guide
3HE 16132 AAAB TQZZA Edition: 01
Failure of one or more fans does not impact traffic. Failure of a single fan is
detected and notified. The fan tray and fan module is hot-swappable.
- On the 7210 SAS-R6 and 7210 SAS-R12, the fan module/tray contains 6
fans.
- On the 7210 SAS-M, 7210 SAS-Mxp, and 7210 SAS-T, the fan module/tray
contains 3 fans.
- On the 7210 SAS-Sx 1/10GE, 7210 SAS-S 1/10GE, and 7210 SAS-Sx 10/
100GE, the fan module is not supported. The devices contain a fixed set of
3 fans with filters on both sides of the chassis.
- On the 7210 SAS-R6 and 7210 SAS-R12, 2 x Switch Fabric/Control
Processor Module (SF/CPM) can be used to provide control plane
redundancy with non-stop routing and non-stop services. The SF/CPM is
hot-swappable.
6.2.1.1.4 Remote Power Supply on 7210 SAS-Sx 1/10GE Platforms
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 Service Redundancy on 7210 SAS-R6 and 7210 SAS-R12
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.
