Displaying Status
Cisco IOS Release 11.2(7)P and later releases support status messages for
Cisco 3620 and Cisco 3640 series routers using the Cisco RPS. Cisco IOS
Release 11.3(2) and later releases support status messages for Cisco 2600 series
routers using the Cisco RPS. Cisco IOS Release 12.2(8)T, Cisco IOS Release
12.2(11)YT, and later releases support status messages for Cisco 3725 series
routers using the Cisco RPS.
Status messages are not supported for the FastHub 400 series hubs, Cisco 1516M
hubs (HP 10BASE-T Hub-16M), Catalyst 1900 series and Catalyst 2820
switches, Catalyst 2900 series and Catalyst 3500 series XL switches, Cisco 2500
series and Cisco 4000 series routers, and Cisco MC3810 multiservice
concentrators.
The show env command (available in Cisco IOS Releases 11.2(7) and later
releases) provides an environmental status of the Cisco RPS. A sample display
follows:
router# show env
Power Supply:
Redundant Power supply is present.
Thermal status is normal.
AC status is normal.
DC status is normal.
Board Temperature:
Warning: Board overtemperature condition detected.
Caution
If the Cisco RPS gets too hot, it shuts down to prevent damage to its components.
If thermal shutdown occurs because the cooling system failed or the ambient
temperature rose above normal operating limits, a thermal warning displays on the
router console, and an SNMP trap is sent before shutdown.
