Displaying and Configuring NPM Cards

The Nodal Processor Module (NPM) is a 68040 microprocessor-based system controller that runs the software for controlling the IGX switch. The NPM communicates with the other system cards over the control bus. The NPM performs the following major functions:

  • Runs the software for controlling, configuring, diagnosing, and monitoring the IGX switch

  • Sends configuration and control commands over the control bus to other cards in the switch

  • Receives statistics, status, and alarm messages from the other cards in the switch

  • Generates all system bus control signals for directing the interpretation of address buses and controlling data transfers

  • Communicates with other nodes in the network

The NPM communicates with all other nodes through a trunk that uses a reserved queue on the trunk. The NPM communication link with other nodes carries information about new connections, topology changes, and rerouting.

Displaying Card Parameters

To display the Card Configuration dialog for this device (using the rear or front view), right-click on the card to display the card "Configure" pop-up menu, then select Configure.

Front Card Configuration Dialog

Use this dialog to display NPM card characteristics, hardware, firmware, and status information.The Card Configuration dialog parameters are described in Table 17-1.


Table 17-1: Card Configuration Dialog Parameters—Front View
Parameter Description

Slot No

Identifies the slot the card is in.

Card Status

Status of the card. Examples are:

  • Active—Card in use. No failure.

  • Standby—Card idle. No failures.

  • Failed—Card failed.

  • Down—Card downed.

  • Mismatch—Mismatch between front card and back card.

  • Missing—An active card has been removed.

FrontCard Type

Identifies the type of front card. In this case, it is an NTM.

FrontCard Serial#

Serial number on the front card.

FrontCard Revision

Model, hardware revision, and firmware revision of the front card.

Card Y-RedStatus

Card Y-Redundancy status. The values can be one of: primary, secondary, null.

AssocCard for Y-red

Associated slot for this card's Y-Redundancy. If the Card Y-RedStatus is primary, the secondary card index displays in this field. If the Card Y-RedStatus is secondary, the primary slot index displays in this field. If Card Y-RedStatus is null, a zero (0) appears in this field.

Processor BOOTId

Boot ID of the processor card. If the card is not a processor card, this field is blank.

Processor RAM Size(Mbytes)

RAM size of the processor card in megabytes. If the card is not a processor card, na appears in this field.

Processor FEPROM Size

FEPROM size of the processor card. Can be one of: meg4, meg3, meg2, unknown, meg8. If the card is not a processor card, "na" appears in this field.

Processor BRAM Size(Mbytes)

BRAM size of the processor card in megabytes. If the card is not a processor card, na appears in this field.

No. Ports (Front Card)

Number of ports on the front card.




Note   This is not a configurable dialog.

Back Card Configuration Dialog
