Overview
Functional description
When you expand a shelf object in the equipment navigation tree, the card slots of the shelf are displayed as child objects. A card slot object is shown as empty when no card is provisioned.
Card slots A and B are reserved for CPM or CSM cards. When you expand a CPM or CSM card object, the processor and flash memory objects are displayed.
Note: Some 7210 SAS and 7250 IXR devices are equipped with a USB flash memory. In the equipment tree and on Alarm Info forms, the NFM-P displays only Flash Memory. The display does not distinguish between compact flash memory and USB flash memory.
Card slot objects for the OS 6250, OS 6400, OS 6450, OS 6465, OS 6850, OS 6850E, OS 6855, OS 6860, OS 6860E, OS 6860N, and OS 6865 appear automatically when a physical device exists. This occurs because the entire device is represented by a card slot object and no daughter cards are associated with these devices.
When the NFM-P discovers a 7210 SAS or 7705 SAR-F, the integrated IOM and daughter card objects appear automatically in the navigation tree.
The 7250 IXR-R6 uses CPIOM cards that provide both CPM and IOM functionality. For information about the NFM-P equipment tree display of card slots and daughter card slots on the 7250 IXR-R6, see Overview.
The 7750 SR-s series of NEs allow for configuration of an IOM-s in a slot position of an XCM-s. This module is an Xiom-s. You can configure either XMA or Xiom-s on XCM-s, but not both. See To configure an Xiom-s card slot.
When the NFM-P discovers a supported PAC FP3 IMM in a card slot, the daughter cards and ports appear automatically in the navigation tree. Daughter cards and ports that are discovered in this way cannot be manually deleted.
Choose Configure Card from the contextual menu of the object and assign a supported card type for the slot. The Assigned Card Type parameter lists the card types that can be assigned to the card slots.
Some card types can be pre-provisioned in a slot before the card is installed in the chassis. A card and daughter card must be provisioned before a port can be configured.
When a card is first configured, the administrative state can be down. The resource is not operationally up until the card is equipped and the administrative state is up. A card can only be provisioned in a slot that is vacant, and no other card can be provisioned (configured) for that specific slot.
The Remove Card option in a contextual menu deletes the card from the slot when the slot and everything contained in the slot is changed to administratively down.
To reconfigure a slot position, delete the card currently in the slot and configure the new card type added to the slot. A card can only be provisioned in a slot when the card type is allowed in the slot.
Note: You can also reconfigure a slot position by changing the chassis mode. The chassis mode determines the minimum card requirements. See Shelf objects in the NFM-P navigation tree for more information about chassis modes.
For example, if a 2 x 10-Gig MDA IOM 2 card is installed in the chassis that is running in chassis mode B, the card behaves as a 2 x 10-Gig MDA IOM Card, B. You can upgrade the chassis mode to C to make the IOM card behave as a 2 x 10-Gig MDA IOM 2 card.
You can configure forwarding plane properties on the properties forms for IOM 3, IMM, and XCM cards. IOM 3 and IMM cards support one forwarding plane, and XCM cards support two forwarding planes — one for each XMA card slot.
Note: You cannot configure a forwarding plane on an XCM card until you have provisioned the corresponding XMA card.
You cannot remove a provisioned XMA card when any of the following is true on the corresponding XCM forwarding plane:
PChip FCS Errors for cards
PChip FCS Error counts can be viewed from the IO Card tab of a Card Slot form. The Card Complex Statistics can be viewed from the Statistics tab of a Card Slot form. When frames of data are being corrupted during transmission, or duplex disparities between switch and the end device causes these errors, the NFM-P raises an alarm.
Note: The PChip alarm details, such as the alarms and statistics, cannot be differentiated whether raised against an MDA or IOM.
