The server blade enclosure is not powered up. Be sure that the server blade enclosure is powered up and all the power connections are intact.

There is a faulty LED. Check the console to see if the switch is booted.

The switch fuse is blown. Send for repair.

Health LED on the switch stays amber for more than 30 seconds and switch does not boot

Action:

The Standby Mode Timeout function is malfunctioning. Force the switch to reboot by pressing the Reset button.

No link LED appears, even after plugging the Category 5 cable in the RJ-45 connector of the external port

Action:

The cable is not properly plugged in. Check the cable at both ends to ensure that it is plugged in and seated properly.

The cable or connector heads are faulty. Replace the cable with another tested cable.

The RJ-45 connector on the switch or LED is faulty.

After checking and replacing the cable, if no link LED displays, check whether the port is transferring data. If yes, the LED is faulty. If no, it could be a faulty RJ-45 connector. Call a service representative.

This could be caused by using a crossover cable instead of a straight through cable.

Cannot access the switch serial console interface using null modem connection from a PC Terminal Emulation Program

Action:

The null modem cable is faulty. Be sure the null modem cable, provided by HP with this hardware, was used.

The connection settings do not match the switch serial settings. Be sure that the PC Terminal Emulation session settings match the switch serial settings.

Error message that the switch failed to complete the system self-testing appears on the serial console screen

Action:

The system diagnostic tests failed. Note the reason for the failure from the serial console screen message and call a service representative.
