Verify Port Connectivity

After you connect a device to the switch module port, the port LED turns amber while the switch

module establishes a link. This process takes about 30 seconds. Then the LED turns green when the

switch module and the attached device have an established link. If the LED is off, the device might not

be turned on, there might be a cable problem, or there might be a problem with the adapter installed

in the device. See the "In Case of Difficulty" section on page 27 for information about online

assistance.

If you experience difficulty, help is available in this section and also on Cisco.com. This section

includes how to reset the switch module, how to access online help, and where to find more

information. For help about the HP blade enclosure, see the HP documentation at

http://www.hp.com/go/bladesystem/documentation.

This section describes how to reset the switch module by rerunning Express Setup. These are reasons

why you might want to reset the switch module:

• You installed the switch module in your network and cannot connect to it because you assigned

the incorrect IP address.

• You want to clear all configurations from the switch module and assign a new IP address.

• You are trying to enter Express Setup mode, and the switch module LEDs start blinking when you

press the Mode button (which means that the switch module is already configured with IP

information).

Resetting the switch module deletes the configuration and reboots the switch module.

Caution

To reset the switch module, press and hold the Mode button. The switch module LEDs begin blinking

after about 3 seconds. Continue holding down the Mode button. The LEDs stop blinking after 7 more

seconds, and then the switch module reboots.

The switch module now behaves like an unconfigured switch module. You can enter the switch module

IP information by using Express Setup as described in the "Using the Onboard Administrator to Assign

an IP Address to the Switch Module and Running Express Setup" section on page 13.
