Installing The D9054 Hd Encoder - Cisco D9054 Installation And Operation Manual

Installing the D9054 HD Encoder

Rack Mounted
The D9054 HD Encoder is a 2U unit with connector access at the rear panel. The
D9054 HD Encoder is intended for mounting in a standard 19" rack with minimum
1U spacing between units to allow adequate ventilation/air flow.
Cooling
The D9054 HD Encoder is cooled by the use of internal fans. The air intake is from
the front and the air outlet is on the rear.
Note: Adequate cooling must be provided equalling 475 W per unit to avoid
overheating.
CAUTION:
The inlet air temperature must not exceed 40°C/104°F at any time.
Grounding
You must ensure that the unit is properly connected to ground in order to meet
safety and EMC requirements. Before any other connection is made, the unit must
be connected to a protected ground terminal as described below:
• Via the three wire power cord of the AC power supply. This connection is
mandatory.
To Mount the D9054 HD Encoder
To mount the D9054 HD Encoder in a rack do the following:
1. Mount L-brackets in the rack to support each D9054 HD Encoder to be installed.
2. Place the D9054 HD Encoder in its position in the rack.
3. Pull the top of the front panel forward such that it is supported by the hinges at
the bottom of the front panel to gain access to the side mounting flanges.
4. Mount the D9054 HD Encoder securely to the rack by securing the mounting
flanges to the rack using the four screws provided.
5. Lift the hinged front panel back into place such that it is seated securely to the
front panel of the encoder chassis, and then fasten it to the mounting flanges
using the two PEM nuts provided.
6. Make sure the air outlet holes on the back of the D9054 HD Encoder are not
obstructed to allow air flow from the front to the back of the chassis.
