Operational Considerations
The following items highlight this functionality:
The warning/logging operations is on or enabled by default.
The CAM recovery is off by default.
The monitoring (via logging) and the card recovery can each be turned on or off independently, as well as on a per-slot
basis.
If no spare XD CAM is available when the recovery threshold is exceeded, the card is left in service after attempted
resets.
The CLI command that controls this feature is:
configure operation event <0x0fcad01f> [slot <slot>] recovery <enable|disable> logging
<enable|disable>
Physical Interface Cards (PICs)
The 16D CAM PIC and the 16D CAM PIC (SPARE) are compatible and should be used with the XD CAM.
Note: The four F-Connectors on the 16D CAM PIC are labeled with the downstream channel numbers for the 16D CAM (0-
3, 4-7, 8-11, and 12-15, respectively), so the labeling on the 16D CAM PIC will not be consistent with the XD CAM channel
numbering.
There are two types of 16D CAM PICs. The normal 16D CAM PIC contains four F-connectors, each labeled with the
appropriate DS channels carried. Each connector is capable of carrying up to eight downstream channels with the XD CAM.
The 16D CAM sparing PIC provides sparing for XD CAMs. In an XD CAM sparing group, the sparing 16D CAM PIC is to the
left of the 16D CAM PICs for which it provides redundancy, as seen from the rear of the chassis.
CAM PIC LED Status
Each F-connector of the CAM PIC has an LED next to it. The LED status descriptions for the CAM PIC are listed in the table
below:
