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.

Selecting the Card and Displaying Card Parameters

Select the card (on both the rear or front view) to display the the Card Configuration dialog by doing one of the following:

• Double-click the NPM Card.

• Select the NPM Card, then select Configure>card.

• Select the NPM Card, right-click to display the card pop-up menu, then select Configure.

• Select the card, then click the Configure button on the toolbar.

Front Card Configuration Dialog

Figure 17-1 shows the parameters for an NPM front card. Use this dialog to display NPM card characteristics, hardware, firmware, and status information.

The Card Configuration dialog parameters are described in .

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.
Front Card 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.
Slot No.	Identifies the slot the card is in.

Back Card Configuration Dialog

Use this dialog to view back card characteristics, hardware, firmware, and status information. The Card Configuration dialog parameters are described in Table 17-2.
