1.) Find an suitable image on cisco.com [i.e. s72033-adventerprisek9_wan-mz.122-33.SXJ1.bin ]
\n2.) Copy the image to the CF of active Supervisor by TFTP or FTP
\ncopy tftp:\/\/IP\/images\/s72033-adventerprisek9_wan-mz.122-33.SXJ1.bin disk0:
\n3.) Verfiy the image against the MD5 and internal checksum
\nverify \/md5 disk0:s72033-adventerprisek9_wan-mz.122-33.SXJ1.bin
\nverify disk0:s72033-adventerprisek9_wan-mz.122-33.SXJ1.bin
\n4.) Delete old Software on active Supervisor CF
\ndel sw1-slot5-disk0:s72033-ipservicesk9_wan-mz.122-33.SXI5.bin
\n5.) Unconfigure other Boot Images
\nconf t
\nno boot system
\nconfig-register 0x2102
\nboot system flash disk0:
\nend
\ncopy running-config startup-config
\n6.) Reload active Supervisor
\nredundancy reload shelf 1
\n7.) Wait for the ex-Active to come up again on local Console, sh redundancy should tell you that the ex-Active is now in Cold Standby as there is an Image mismatch. Thats ok, Image does work, so now lets swap the CF cards
\n8.) Reload now active Supervisor
\nredundancy reload shelf 2
\n9.) Wait for the second System to come up again, the VSS should run again in Active \/ Standby Hot Mode
\n10.) Copy Bootimage from shelf2 (with CF of shelf1) to shelf1 CF
\ncopy sw-2-slot5-disk0:s72033-adventerprisek9_wan-mz.122-33.SXJ1.bin sw-1-slot5-disk0:
\n11.) Delete other old images form shelf1 CF
\n12.) Done<\/p>\n
Not the best \/ Cisco way, but it should hold your Active \/ Standby Config in right order.<\/p>\n
