Procedure
1. For 23" mounting, attached the 23" mounting bracket adapter plates to the standard 19" mounting brackets.
2. Position the system in the relay rack or cabinet equipment rack.
3. Secure the system to the relay rack or cabinet equipment rack using hardware as shown in Figure 6.1 (see Figure 6.1 for
recommended torque). Use grounding washers as indicated in Figure 6.1.
NOTE!
Install (orient) the ground washers so the teeth dig into the mounting angles for a secure ground connection.
NOTE!
Compliance with Telcordia GR-1089-CORE requires that prior to mounting the system to the equipment rack:
•
All paint must be removed from the front surface of each equipment rack rail where it mates with a shelf-mounting
bracket, so that good metal-to-metal contact can be established between the shelf and rack.
•
The shelf-to-rack mating surfaces must be cleaned.
•
Electrical anti-oxidizing compound must be applied to the shelf-to-rack mating surfaces.
