Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. To see translations of the warnings that appear in this publication, refer to the "Regulatory Compliance and Safety Information" in this document. |
To remove the multipoint headend power feed panel, complete the following procedures:
The multipoint headend power feed panel is a required component of the multipoint wireless system. The unit should be removed only when the transverters supported by the power feed panel are not transmitting a signal. Use the procedures established at your installation, and the shut command, to shut down the wireless link.
To disconnect the DC power from the power feed panel, complete the following steps:
|
Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. To see translations of the warnings that appear in this publication, refer to the "Regulatory Compliance and Safety Information" section in this document. |
Step 2 Remove the terminal blocks from the receptacles on the rear of the power feed panel (see Figure 5).
To remove the cables from the power feed panel, complete the following steps:
 |
TimeSaver To make replacement easier, be sure that all cables are labeled. |
Step 2 Remove the cables (as many as four) from the N-type connectors on the rear of the power feed panel (see Figure 7).
Step 3 Remove the screws from the ground lug (see Figure 8).
When removing the power feed panel from an equipment rack, refer to the following subsection, "Removing the Power Feed Panel from an Equipment Rack." When removing the power feed panel from a wall, refer to the "Removing the Power Feed Panel from a Wall" later in this section.
To remove the power feed panel from an equipment rack, complete the following steps:
Step 2 Lift the power feed panel out of the rack and place it on a work surface.
To remove the power feed panel from a wall or plywood backboard, remove the mounting screws
from both brackets while supporting the power feed panel (see Figure 10). After removing the mounting screws, move the power feed panel to a work surface.
Remove the brackets attached to each side of the power feed panel. Refer to Figure 11 when the unit is mounted with the front panel forward. Refer to Figure 12 when the unit is mounted with the rear panel forward. Refer to Figure 13 when the unit is mounted with the Telco center-mount brackets.

Note Recommended torque for attaching the cables to the N-type ports is 35 to 40 inch-pounds. |
Step 3 Attach the cables (as many as four) to the SMA connectors on the front of the power feed panel
(see Figure 22).
|
Note Recommended torque for attaching connectors to SMA ports is 7 to 9 inch-pounds. |
After replacing the power feed panel and attaching the cables, you must reinstate the power. To reinstate the power to the unit, complete the following steps:
Step 2 Plug the terminal blocks into the receptacles on the rear panel of the power feed panel (see Figure 24).
 |
Caution Never reinstate the power to the multipoint headend power feed panel before the terminal blocks are plugged in, or when any of the four power/breaker switches on the front of the unit are in the ON position. |
Step 3 Remove the tape from the circuit breaker switch handle, and reinstate power by moving the handle of the circuit breaker to the ON position.
Step 4 Switch to the ON position the power/breaker switches on the front of the unit that will be on active circuits (see Figure 23).
Using the procedures established at your installation, reinstate the wireless link with the no shut command.
