16 Rear Panel, Short-Wave and Long-Wave Hubs

Rear Panel, Short-Wave and Long-Wave Hubs

Three fans, located in a customer-replaceable module at the rear panel, cool the hub. If one

fan fails, the remaining two fans cool the hub temporarily, but it is important to replace the

module as soon as possible (see chapter5, Maintenance and Replacement).

Figure 3 Rear Panel

Caution Although the module will continue to run with two fans, a full complement of

fans ensures system and data integrity.
