Alcatel-Lucent 9500 MPR User Manual page 154

Use extreme caution when connecting or disconnecting the
ODU cable on the MSS/RADIO (MD300) module. The shelf bat-
tery voltage is present on the center conductor of the connec-
tor. When removing or replacing a MSS/Radio (MD300)
module, withdraw the module from the shelf before discon-
necting the cable from the ODU. Failure to follow these cau-
tions may cause arcing and/or possible power spikes that
could affect traffic on other links installed at the node.
Removing an in-service module in an unprotected link will
cause loss of traffic. Removing an in-service module in a pro-
tected link requires switching the traffic onto the protected
channel.
•
The main CSM, protected CSM, and Fan module have dedicated slots.
•
The MSS/DS1 (P32E1DS1) module, the MSS/DS3 (P2E3DS3) module and the MSS/
Radio (MD300) modules can be installed in any of the universal slots (3 through 8).
•
The MSS-8 can be configured with a maximum of six modules; three protected
modules, six non-protected modules, or a combination of protected and non-protected
modules.
•
For protected modules, main and protected modules must be plugged in side-
by-side.
•
All plug-ins can be removed and installed with power applied.
If the main CSM fails, traffic and platform data will switch to
the protected CSM automatically. Do not remove power from the
NE during the removal and replacement of the failed main CSM
without first reviewing/performing the following procedure:
