•One of any of the following optional modules:
–16-port hot-swappable switching module with connections to the switch fabric and to the supervisor module for system management.
–32-port hot-swappable switching module with connections to the switch fabric and to the supervisor module for system management.
–Hot-swappable IP Services module (IPS) that provides FCIP services and iSCSI services capability
–Hot-swappable Advanced Services Module (ASM) that provides virtualization services
•Two power supplies that are redundant by default and can be configured to be combinant if desired.
•Redundant, self-monitoring clock modules for system clock generation.
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.
Power Supplies
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.
