Open Caveats in Software Release 5.1(1)CSX

This section describes caveats for Catalyst 6000 family software release 5.1(1)CSX.

• In systems with redundant supervisor engines, occasionally, during bootup or after a switchover

to the redundant supervisor engine, a switching bus sequence error syslog message is reported to

the console as follows:

%SYS-1-MOD_SEQERROR:Switching bus sequence error occurred on module 8

This message might be generated for some or all installed modules. Ignore this message. This

problem is ﬁxed in software release 5.2(1)CSX. (CSCdk81972)

• When a switching module temperature sensor exceeds its minor threshold, the module’s Status

LED stays green; the Status LED should go to orange. When a switching module temperature

sensor exceeds its major threshold, the module’s Status LED shows green, red, and then stays

green; the Status LED should go to red. This problem is ﬁxed in software release 5.2(1)CSX.

(CSCdk92667)

• When you turn off the power on any module, you cannot turn the power back on through SNMP.

The workaround is to use the CLI command set module power up mod_num. This problem is

ﬁxed in software release 5.3(1)CSX. (CSCdm23288)
