Hub Reset Button

Pressing this button, which is active on the active controller module only, resets all installed modules including both active and standby controller modules.

If you issue the reset hub command at the 8260 console, it will give you the same result as using the hub reset button.

Note

Prior to resetting a hub, ensure that you save all parameter changes made; otherwise, you will have to re-enter them. Also remember that when the hub is reset, the network operation is disrupted.

LED Test Button

The LED test button is used to verify LED operation for all LEDs on all 8250 and 8260 modules installed. When you press the LED test button, every LED on every installed module should light up for approximately 5 seconds. Any LED that does not light is defective.

After 5 seconds, the port status LED will blink the number of times representative of the network to which that port is assigned for every port assigned to a backplane network. For example, the number of times an 8250 module port status LED can blink ranges from 1 to 7 for token-ring networks, from 1 to 3 for Ethernet networks and from 1 to 4 for FDDI networks. The port status LED display will last approximately 25 seconds.

For every port which is not assigned to a backplane network, the port status LED will turn off and remain off for approximately 25 seconds.
