INSTALLATION & SET-UP

3. 3 Optional rackmounting
Rackmounting kits may be used to mount two WC3445 units side by side in a 19” rack.
The first two of these kits have a flat mounting plate with separate cut-outs for power cables
and signal cables. 80-05-252 is suitable for AC mains powered units, while 80-05-254 is
suitable for units powered by -48VDC.
The third kit, Part no 80-05-256, has a recessed plate to permit fibre bends to be made within
the envelope of a 19” rack. It also has a single cut-out for all connections to the rear of the
WC3445. The installation method is the same in all cases.
First remove the two rear panel screws securing each unit’s lid. Fasten the two WC3445
units to the rackmount adaptor plate using the screws that you have removed, as shown in
the illustrations below.
Then secure the rack mounting plate complete with the two WC3445 units to the 19” rack
using the locating holes at the ends of the adaptor plate. If you have set the bit-switches on
the base plate of the units before fixing them to the adaptor plate, check that the settings are
still correct.
