Cisco Cisco MGX 8880 Media Gateway Release Notes

Before adding redundancy, you must ensure that E:RPM/auto_config_slot# is created. This may 
require that you log in to the primary card through the command line and manually add boot config 
e:auto_config_slot# followed by a write mem command.

Executing the switchcc command back-to-back using the switchredcd command can cause 
problems. We recommend allowing at least 5 seconds between switchredcd and a switchcc.

Cisco IOS software on a standby card should be the same or later release than the active RPM-XF 
card release.

If the card is in a redundancy group, do not boot the card from an image on a TFTP server. Boot the 
card from image in bootflash or PXM disk only.

Do not configure the standby RPM-XF.
