16.8 Multishelf Configuration Alarming
Multishelf systems can share a single IP address among shelves and also correlate optical signal alarms.
Ethernet alarm-raising for this configuration also differs from alarm-raising for single-shelf
configurations. This section explains how alarms are viewed on a multishelf configuration, how alarm
locations are determined, and how multishelf alarming differs from single-shelf alarming.
16.8.1 Viewing Multishelf Alarmed Entities
The multishelf view in CTC shows which slots are occupied in each shelf of the configuration
(Figure 16-5).
Figure 16-5 Navigating to Shelf View from Multishelf View
You can determine where an alarm is raised by viewing the Object column. The entry there (for example,
FAC-1-3-1) tells you the entity (“fac,” or facility), shelf, slot, and port. In shelf view, the Alarms and
Conditions tabs also contain a Shelf column that indicates where the alarmed card is located.
16.8.2 Multishelf-Specific Alarming
The following sections explain how Ethernet communication alarms and correlated multishelf alarms are
processed in the ONS 15454 DWDM system.
