identical fan modules. If a fan fails, it should be replaced at the earliest
opportunity.
The fan modules are hot-swappable; you do not need to power down the
switcher to install or remove either fan.
NOTE: DMS 2000 and DMS 3200 — The fans are xed in place
and are not eld replaceable.

plate (identifying the rows of the adjacent DVI input and output
connectors) to the fan. Retain the plate.
2. Rotate the top and bottom knurled knobs to completely loosen the
captive screws (see gure 16).

module edges with
