Check the Status Field

Check the Status Field

The Status field (

Figure 4-3

) displays the severity and number of problems

(hardware issues and misconfigurations) on the switch. If no problems exist, the
field shows that the overall switch operation is normal. This field is always visible
during the device manager session. It is below the Front Panel view.

Figure 4-3

Status Field

Choose a problem in the list, and then click Get Details. This displays a complete
troubleshooting report, including the problem highlighted and recommended
actions to resolve the problem. For information about diagnostics, see the

“Run a

Diagnostic Test” section on page 5-2

.

RPS

Off (dark)

No redundant power supply (RPS) is connected.

Solid green

RPS is available to provide back-up power.

Blinking green

RPS is providing back-up power to another device.

Blinking amber

RPS is providing power to the switch.

Solid amber

RPS is in standby mode, or RPS is faulty.

SETUP

Off (dark)

Switch is configured as a managed switch, or switch is operating as an
unmanaged switch.

Solid green

Switch is in initial setup.

Blinking green

Switch is in initial setup or in recovery, or initial setup is incomplete.

Solid amber

Switch failed to start initial setup or recovery because there is no
available switch port to which to connect the management station.
Disconnect a device from a switch port, and then press the SETUP
button.
