The DRMM12 Rack Mount supports a single Drake Power
Supply and up to (8) modular Drake digital headend units to
configure a professional quality, modular, headend system,
which optimizes rack space. The DRMM12 mounts in a
standard 19" wide equipment rack and requires 3 1/2" of
vertical rack space. After installation of the PS8 Power Supply,
there are 12 single width slots available. Up to 8 separate
modules in combinations of 1, 2, or 3 units wide can be
installed into the rack. The PS8 will power up to 8 modules.
Identify the following items shipped with this kit of rack mount
assembly and cable assembly:
(1) DRMM12 Rack Mount chassis.
(1) Wire, ground bonding chassis to power supply
(P/N: 2700017).
(2) End Caps, Gray (P/N: 4801560).
Installation:
Adequate ventilation is very important in multi-channel
installations. Rack units should be spaced apart by at least
1 3/4" wherever possible, and some air movement is advis-
able in enclosed rack cabinets. Excessive heat will shorten
the life of components and individual module(s). Power
supply performance will also be degraded without proper
cooling.

Power Supply
If desired, the supplied gray end caps can be installed over
the mounting ears of the DRMM12 and secured by the rack
support screws.
Locate the Power Supply (sold separately). Prior to sliding the
power supply into the right-hand side top and bottom slide
rails of the DRMM12, loosen the #6-32 screw located on the
top surface of the power supply. Position the free end of the
ground wire lug (other end of wire fastened to DRMM12) under
the #6-32 screw, and tighten the screw to secure the ground
wire. Slide the power supply into the DRMM12.
If necessary, use the following steps to remove the Drake
Power Supply from the rack:
1) Remove the module immediately adjacent to the Drake
Power Supply. Be aware that the module power cable will
become disconnected from the rear when the module is
removed.
2) Now grasp the edge of the Drake Power Supply front panel
and remove the unit from rack.
3) Reconnect the module power cable then replace the
adjacent module as required.
