Remote maintenance, management, and control
...................................................................................................................................................................................................................................
First maintenance tier
The maintenance procedures of the Metropolis
®
AMU systems are built on two levels
of system information and control. The first maintenance tier consists of the LEDs on
the equipment. There are six LEDs on the front of the main board of Metropolis
®
AMU: Two are for unit level indications and four for failure indications related to each
individual SFP. Additionally there are LEDs on option cards and near to the SFPs. The
LEDs indicate basic alarms or basic operation states.
Second maintenance tier
The second maintenance tier employs the Lucent Technologies network management
system. Detailed information and system control are obtained by using the ITM-CIT
(Craft Interface Terminal), which supports provisioning, maintenance and configuration
on a local basis. A similar facility (via a Q-LAN connection or via the DCC channels)
is remotely available on the element manager or through Lucent’s Network
Management Systems or Lucent NMS, which provides a centralized maintenance view
and supports maintenance activities from a central location.
Lucent Network Management Systems
Lucent’s Network Management Systems or the Lucent NMS fully support the
management of Metropolis
®
AMU.
Fan Management
A fan is available for mounting below the 2m/4o version, below the vertically mounted
1m/1o version (1 per shelf) or next to the horizontally mounted 1m/1o version (1 per
shelf). The same fan can be used in all cases. The fan is in-service replaceable,
provided that proper care is taken with the cabling. The fan is powered and managed
via the USB interface on the front of (one of the) Main Units. For more details, refer
the Metropolis
®
AMU User Operations Guide.
Note: When two fans are placed under the 2m/4o version, 2 trib slots and 2 main slots
or 4 trib slots can be cooled effectively.
The presence of USB powered/controlled fans can be established on a remote
management system. Provisioning of fans is not necessary; they are auto-provisioned
after autonomous detection by the AMU hardware. Alarms will be raised if a fan fails
or is removed.
Special Mounting Brackets
To use the horizontally positioned 1m/1o version in combination with a fan unit, it
must be mounted with a specific mounting bracket that allows sliding in and out of the
fan unit.
