Mounting the Bracket to the Unit
NOTE: Use this procedure in conjunction with either the 489-BEP or 589-BET installation and
cabling instruction sheets, as appropriate.
1. Place enclosure cover-side down.
2. Place the short piece of the bracket (Item #2) onto the top right of the enclosure so that the slot is to the
right, the depressed mounting hole lines up with the top right most boss, and the flush mounting hole
lines up with the top center most boss. This should have the widest portion of the bracket facing inward.
(See the following illustration.)
3. Insert one of the #10 thread-cutting screws into the top-right mounting hole.
NOTE: DO NOT fully torque down on the #10 thread-cutting screws - the bracket needs some slack in order
to accommodate the different manufacturing tolerances of the different frames.

4. Place the long piece of the bracket (Item #1) onto the top left of the enclosure so that the slot is to the left,
the raised mounting hole lines up with the top left most boss, and the flush mounting hole lines up with
the top center most boss. This position places the widest portion of the bracket facing inward.
With the slot to the left and the holes to the top of the centerline of the bracket, Item #1 has 3 raised holes
and 3 flush holes. The right most raised and flush holes are for mounting to a 23-inch frame, the center
raised and flush holes are for mounting to an ETSI frame, and the left raised and flush holes are for
mounting to a 19-inch frame. Use the holes that are appropriate for sizing the bracket to your frame.
5. Insert two more of the #10 thread-cutting screws into the top-center and top-left mounting holes. DO
NOT fully torque down on the screw.
6. Place the second long piece (Item #1) onto the bottom left of the enclosure so that the slot is again to the
left, the depressed mounting hole lines up with the bottom left most boss, and the flush mounting hole
lines up with the bottom center most boss. The widest portion of the bracket faces inward.
7. Insert one of the #10 thread-cutting screws into the bottom-left mounting hole. DO NOT fully torque down
on the screw.
8. Place the second short piece (Item #2) onto the bottom right of the enclosure so that the slot is to the
right, the raised mounting hole lines up with the bottom right most boss, and the flush mounting hole lines
up with the bottom center most boss. The widest portion of the bracket faces inward.
9. Insert the last two of the #10 thread-cutting screws into the bottom-center and bottom-right mounting
hole. DO NOT fully torque down on the screw.
Mounting the Unit to a Bay
1. For a more flush mounting arrangement, place the unit in from the back of frame. For a higher density or
one-sided mounting arrangement, place the unit in from the front of frame.
2. Align the slots of the bracket with the mounting holes in the bay.
3. Use 12-24 screws, M6 screws, or M6 cage nuts to fasten the unit to the bay.
4. Repeat as needed.
