24 Stratum Installation and Maintenance Guide
Rack Mounting the IDU
Three sets of bracket holes for rack mounting allow the IDU to be mounted with its connectors facing the rear or
front, as shown in Figure 13 below. The center set of holes also allows the IDU to be mounted in center rail racks or
on the surface of a wall if the brackets are installed facing down.
Attach the two rack mounting brackets on each side of the IDU. Use four #8-32x1/2” Pan Head screws and #8 lock
washers (under the screw head) for each bracket. Tighten the screws securely.
Mount the IDU in an equipment rack near the networking equipment (hub, server, switch, or router) to which it will
be connected. Use two #12-24x3/4” screws in each rack bracket to mount the unit.

Precautions when Rack Mounting the Stratum IDU
When rack mounting your Stratum IDU, you should take the following precautions for safety and to ensure proper
operation of the equipment:
The maximum ambient temperature for the Stratum IDU is 50º C. When installed in a rack, whether closed or open,
the ambient temperature within the rack should not exceed 50º C .
Stratum IDUs have fans and ventilation holes to ensure proper air flow and maintain correct internal temperature.
Do not block the fans or ventilation holes.
When mounting any equipment in a rack, you must consider the mechanical loading of the rack . Heavier
equipment should be placed near the bottom of the rack and equipment should not be mounted in such a way as to
cause instability. Special precautions should be taken with mountings that slide out for easier access to equipment.
Such mountings can cause instability resulting in unsafe conditions and possible tipping of the rack.
Ensure that the power source, wiring, and over-current protection to rack mounted equipment is rated such that it
can support the cumulative load of all equipment.
Do not exceed the capacity of the wiring or over-current
protection.
Reliable grounding of the Stratum is required.
The rack should also be grounded. If power distribution strips are used, ensure that they are properly grounded as
well.
