Nortel Networks NTRN10AN, 3500 manual Alarms and provisioning data

3-58Hardware feature descriptions

The NPx communicates with the co-located SPx through the backplane over Ethernet. The NPx also allows up to 16 nodes with NPxs to be daisy-chained through the intershelf local area network (ILAN) port on the ILAN or NPx circuit pack.

The NPx circuit pack provides access to the ILAN1, ILAN2, and COLAN ports on the LOAM.

Note: The COLAN is 10BASE-T and half duplex

The NPx supports user accounts with a level 5 user privilege code (UPC) for network surveillance purposes. Logging in to the NPx using a user account with level 5 UPC from a local connection, you can retrieve alarms and events from all network elements in the NPx span of control. The NPx can have up to 16 network elements in its span of control. The network elements in the NPx span of control can be any combination of OPTera Metro 3000 Multiservice platform series network elements.

The NPx supports file transfer to and from Preside and Multiservice MOA for electronic software delivery, and to and from a PC to install files on the system. The NPx also allows other network processors or shelf processors to retrieve new software loads for upgrade purposes.

Note 1: One NPx can surveil a mixed span of control (that is, OPTera Metro 3100, 3300, 3400, and 3500 network elements all will be seen in an NPx circuit pack’s span of control).

Note 2: An NPx circuit pack can store up to 7 software loads. Before transferring a software load to the NPx, ensure there is at least 20,000 kB of space available on the NPx.

TL1 sessions

The NPx hosts TL1 sessions for commands related to the NPx and NPx facilities.

Alarms and provisioning data

NPx provisioning data is backed up at the co-located shelf processor. The NPx reports alarms for NPx facilities. The co-located SPx reports NPx equipment alarms on behalf of the NPx. When the NPx is restarted, it receives all its provisioning data from the co-located SPx. The Save and Restore functionality saves each individual network element’s backup data to the repository located on the NPx.

Reset button

When the reset button is pressed, the network processor hardware and software initialize. During the initialization process, all the LEDs on the NPx turn on and communications provided by the NPx are unavailable. The NPx reset button should only be used when the NPx is not responding.
