Troubleshooting the 600/610

Diagnostic Tips:

Tip Problem Solution

➊

The unit is not

plugged into an

active AC power

source, or the

unit’s power

supply may have

failed.

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

sure these connections are snug.

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

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

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

different power cord.

If the power source and power cord are OK and this condition persists, the unit’s power

supply may have failed. Call your HP-authorized LAN dealer, or use the electronic support

services from HP to get assistance.

➋

A hardware

failure has

occurred. All the

LEDs will stay on

indefinitely.

Try power cycling the unit. If the fault indication reoccurs, the unit may have failed. Call

your HP-authorized LAN dealer, or use the electronic support services from HP to get

assistance.

➌

The unit has

experienced a

failure.

Try resetting the unit by power cycling the unit.

If necessary to resolve the problem, contact your HP-authorized LAN dealer, or use the

electronic support services from HP to get assistance.

➍

One or more of

the unit cooling

fans may have

failed.

Try disconnecting power from the unit and waiting a few moments. Then reconnect the

power to the unit and check the LEDs again. If the error indication reoccurs, one or more

of the fans has failed. The unit has four fans and may continue to operate under this

condition if the ambient temperature does not exceed normal room temperature, but for

best operation, the unit should be replaced. Contact your HP-authorized LAN dealer, or

use the electronic support services from HP to get assistance.

➎

There is an over

temperature

condition in the

unit.

Check the log file of the connected switch for more detailed information. Make sure the

air flow around the sides and back of the unit is not restricted. Also check to see that no

hot exhaust air from another device is blowing on the unit. If this unit is in a fully enclosed

rack, make certain that the ambient temperature inside the rack near the unit does not

exceed 55°C (131°F) for the HP 600 RPS/EPS or 50°C (122°F) for the HP 610 EPS.

➏

The port for

which the LED is

blinking has

experienced a

failure.

An over-current condition may have been caused by a connected device. Unplug the

cable connected to the port, then plug it back in. If the condition returns, carefully power

cycle the unit (be careful that other devices connected to the unit will not be adversely

affected). If the fault indication reoccurs, the unit port may have failed. Call your HP-

authorized LAN dealer, or use the electronic support services from HP to get assistance.

➐

RPS power is not

available to the

connected

device.

A higher priority RPS port is using RPS power from the HP 600 RPS/EPS. The LED blinks

even if the connected device does not require RPS power at this time. The blinking LED

is indicating that there is no RPS power available to that device should it be required.

Higher priority ports will get RPS power if it is needed, so their Power Status LED remains

off. The highest priority device should be connected to RPS port 1 to ensure that it receives

power if it is needed.
