CrossFire 8600/8605 Token-Ring Switches v. 1.2, P/N: 710001641

Switch Theory of Operation

The CrossFire 8300 Switch Stacker also accommodates an optional switch matrix
8301, which includes a redundant power supply, ensuring the highest degree of
resilience in the stack of switches.

➽

Caution: The redundant power supply unit CrossFire 8311 is not hot-swappable.
Both the CrossFire 8311 unit and the switch must be off before connecting or
disconnecting the DC power cable.
