Replacing a BIP external alarm cable to an MFA150

Prerequisites
Procedure steps
Passport 15000, 20000 Hardware Installation, Maintenance, and Upgrade
Replace a BIP external alarm cable to an MFA150 system of ac rectifiers to
have external alarm reporting.
• You must be familiar with "Safety considerations and best practices"
(page 53).
• When the cable connection is disrupted, the reporting of alarm 70120050
is suspended. The alarm indicates a failed rectifier to the network
management software of Preside Multiservice Data Manager. If the
alarm condition still exists after the cable is re-connected, the alarm is
reported.
1 Locate the BIP connector at the rear of the BIP.
2 Align the connector on the replacement cable with the connector on the
BIP. Each connector fits only one way.
3 Unplug the Berg connector at J2 on the rear of the BIP.
4 Align the replacement cable connector with the BIP connector and press
them together until the tab on the side engages.
5 Route the cable parallel to the existing cable's path. Fasten the cable
loosely along the path. Decide whether to unfasten the old cable now or
later, whichever is easier for adding the replacement.
6 At the controller of the MFA150, access the connection points of the cable
inside. Copy the method of connection at the TB2 terminal blocks on the
controller cards for power feeds A and B. For an example of the wire
connections from the cable assembly, refer to the figure "Connections for
external alarm cable P0940531 at an MFA150" (page 782).
