Note
The clock modules in the Cisco MDS 9216 Switch have a
field-measured mean time between failures (MTBF) of
approximately 3.2 million hours or 365 years. In the unlikely event of
a clock module failure, the system generates an error message and a
switchover from one clock module to the other occurs, causing the
system to reset automatically. These clock modules are not hot
swappable, so system downtime must be scheduled to replace a failed
clock module.
The Cisco MDS 9216 Switch supports dual hot swappable 845 Watt AC power
supplies, each of which can supply sufficient power to the entire chassis should
one power supply fail. The power supplies monitor their output voltage and
provide status to the supervisor-fabric module. To prevent the unexpected
shutdown of an optional module, power management software only allows a
module to power up if adequate power is available.
