SFP Transceivers

A single-mode or multimode fiber-optic cable attaches to a port through a
pluggable small form factor (SFP) transceiver. The SFP provides a duplex LC
interface, and can be detached from the switch port for easy replacement. Two
fiber-optic transceiver types are available:

Cooling Fans

Four fans (each a separate FRU) provide cooling for the switch power supplies
and the control processor (CTP) card, as well as redundancy for continued
operation if a single fan fails.
Each fan FRU can be replaced while the switch is operating.
