Important: 1:1 redundancy is supported for these cards however some subscriber sessions and accounting information may be lost in the event of a hardware or software failure even though the system remains operational.
• 2 1000 Gigabit Ethernet Line Cards (XGLC): 1 active, 1 standby. Note that the XGLC, which is a full-height line card that populates both the upper and lower slots of the chassis, uses a side-by-side redundancy scheme. Refer to the Hardware Installation and Administration Guide for more information.
Important: When an SMC or SPIO failover occurs, the standby SMC or SPIO automatically becomes active. However, should the failed card's error condition be corrected (by replacement or configuration change), the state of the repaired SMC or SPIO does not automatically return to the active state. This migration must occur through manual intervention by a system administrative user.
< 5 sec. interrupt until new A11/GTP-C manager is available (new sessions only)NOTE: Applies only when A11/GTP-C manager is on failed cardImportant: If the session recovery feature is enabled, then a processing card hardware failure will not cause any loss of fully established HA subscriber sessions. This feature does, however, require a minimum processing card configuration per chassis of three active cards and two standby to prevent all data loss and session recovery.
Important: When a processing or line card failover occurs, the redundant component (when installed) automatically begins providing service. However, once the failed card's error condition is corrected (by replacement or configuration change), there is no automatic return of control to the repaired processing or line card. This migration must occur through manual intervention by a system administrative user.
