Problem

Cause

Solution

Power LED flashes red five

times, once every second,

followed by a two second

pause, and the workstation

beeps five times.

Memory is installed

incorrectly or is bad.

CAUTION:

Disconnect AC power from the

workstation before reseating or replacing

components because there is power to the

system board even when the workstation is

powered down.

Ensure DIMMs are loaded in the correct

slots.

Reseat DIMMs.

Replace DIMMs one at a time to isolate the

faulty module.

Replace third-party memory with HP

memory.

Replace the system board.

Power LED flashes red six

times, once every second,

followed by a two second

pause, and the workstation

beeps six times.

Video card is not seated

properly or is bad, or

system board is bad.

CAUTION:

Disconnect AC power from the

workstation before reseating or replacing

components because there is power to the

system board even when the workstation is

powered down.

Ensure that auxiliary power cable is

connected correctly, if applicable.

Reseat the graphics card.

Replace the graphics card.

Replace the system board.

Solving network problems

These guidelines do not discuss the process of debugging the network cabling.

Table 6-13

Network problems

Problem

Cause

Solution

Wake-on-LAN feature is

not functioning.

Wake-on-LAN is not

enabled.

Use the Network control application to enable

Wake-on-LAN.

Network driver does

not detect network

controller.

Network controller is

disabled.

Run Computer Setup and enable network

controller.

Incorrect network driver.

Check the network controller documentation

for the correct driver, or obtain the latest driver

from the manufacturer’s website.

Network status link light

does not turn on or it never

flashes.

The network status light

should flash when there is

network activity.

No active network is

detected.

Check cabling and network equipment for

proper connection.

Network controller is not

set up properly.

Use the network control application to verify

that the device is working properly.

Network driver is not

properly loaded.

Reinstall network drivers.

System cannot auto-sense

the network.

Disable auto-sensing capabilities and force

the system into the correct operating mode.
