There is a jumper on the fan controller board, at the corner closest to
the top-rear of the chassis as installed. It is labeled "FILT BLK" and the
two positions are "ENABLE" and "DISABLE". The fan ships with the
jumper in the disable position which prevents the filter alarm from
working. To enable the filter alarm, move the jumper to the "ENABLE"
position. This is the only jumper on the board. The OSP cabinet must
be engineered so that the DMXtend does not impede air flow to other
equipment in the cabinet. The OSP cabinet must be engineered to pro-
vide a two inch open space on the left and right sides of the DMXtend
for air flow. Mounting frame and flanges may intrude on this space.
Important!
Be sure to mount the shelf using the thread-forming
screws provided with the shelf to ensure a solid ground connection
from the bay to the shelf.
Important!
For bays that use power coat paint e.g. most 19" bays,
studies on that type of paint indicate that the material is not always
removed cleanly using the thread forming screws and can create a
poor ground, thus we recommend a secondary ground be used. The
secondary ground would consist of a 12 AWG wire from the UL
(Green M5 Screw) safety ground on the lower left side of the rear of
the shelf to the bayframe (where the bayframe has been scraped
clean of paint and treated with no-ox) or directly to the office
ground. See Figure 1-4, Safety ground screw. (page 1-13)

Step 9
Mount the ESD Jack Stud on the rear of the bayframe where it will be
accessible when accessing the rear of the shelf.

Step 10
If fiber spools are to be used, attach the spools to the Metropolis
®
DMXtend using the Fiber Spool Bracket Kit drawing 848949152.
Attach the bracket to the shelf first and then the top fiber spool to the
bracket. The lower fiber spool will need to overlap the top spool to snap
