Problem Solution

➊

The power supplies

installed in the

switch are not

plugged into active

AC power sources,

or the power supply

may have failed.

1. Verify the power cord is plugged into an active power source and to the switch.

Ensure these connections are snug.

2. Try power cycling the switch by unplugging and plugging the power cord back in.

3. If the Power LED is still not on, verify the AC power source works by plugging

another device into the outlet. Or try plugging the switch into a different outlet or

try a different power cord.

If the power source and power cord are OK and this condition persists, the switch

power supply may have failed. Call your ProCurve authorized LAN dealer, or use the

electronic support services from ProCurve to get assistance. See the Customer

Support/Warranty card for more information.

➋

A switch hardware

failure has

occurred. All the

LEDs will stay on

indefinitely.

Try power cycling the switch. If the fault indication reoccurs, the switch may have

failed. Call your ProCurve authorized LAN dealer, or use the electronic support

services from ProCurve to get assistance. See the Customer Support/Warranty card

for more information.

➌

The switch has

experienced a

backplane failure

during self test.

The failure may be just in the communications with a single module slot, or it might

be more significant. Start a console session with the switch, and at the CLI prompt

issue the command show logging. In the event log that is displayed, there will

be messages that describe the extent of the problem. If the problem is with individual

slots, the remainder of the switch slots will be fully operational and can be used until

you get a chance to replace the switch.

If necessary to resolve the problem, contact your ProCurve authorized LAN dealer,

or use the electronic support services from ProCurve to get assistance. See the

Customer Support/Warranty card for more information.

➍

The module

installed in the slot

that corresponds to

the letter that is

blinking is an

invalid module.

The fact that the Link and Mode LEDs never are lit on the module indicates that it is

a ProCurve Switch gl module and should not be used in your zl switch.

Ensure you have installed a zl module in the slot. ProCurve xl/gl modules

will fit in the slot, but they are not compatible with your ProCurve zl switch.

Check to ensure the module has a Blue “zl module” symbol on it.

Remove the module from the switch and replace it with a zl module, or

recover the slot with the cover plate. You can remove and replace the module

without having to power down the switch. Call your ProCurve authorized LAN dealer,

or use the electronic support services from ProCurve to get information on

supported Switch zl modules. The modules that are available as of the printing of

this manual are listed on page 1-13.
