Activity Lights

The ArmadaStation EM has three activity lights.

Top and Bottom MultiBay Activity Lights

The top and bottom MultiBay activity lights are located on the front/right corner of the
ArmadaStation EM. These lights turn on when information from a removable drive
inserted in the ArmadaStation EM MultiBays is accessed.

Power/Suspend Light

The power/suspend light is located on the front/right corner of the ArmadaStation EM.
This light turns on when the system (computer and ArmadaStation EM) is turned on;
this light blinks when the system is placed in Suspend.

MultiBays

The ArmadaStation EM features two MultiBays. The MultiBays support the same
drives that are used in the E and M Series computer MultiBay, including hard drives
(installed into a MultiBay hard drive adapter), CD-ROM drives, DVD-ROM drives,
diskette drives (bottom MultiBay only), and SuperDisk LS-120 drives. The bottom
MultiBay can also be used to charge MultiBay battery packs.

The ArmadaStation EM MultiBays support the following devices:

Half-Height Bay

The ArmadaStation EM features one standard half-height bay, which is located on the
front of the ArmadaStation EM. The half-height bay supports any standard half-height
drive or a half-height MultiBay adapter.

Security Lock

The ArmadaStation EM features a security lock that allows all computer and
ArmadaStation EM resources (hard drives, diskette drives, CD-ROM drives, PCI
expansion boards) to be secured to the system (computer and ArmadaStation EM).
When the security lock is engaged, the computer cannot be undocked, and no drives or
PCI expansion boards can be removed from the system.

PCI Expansion Boards

The ArmadaStation EM provides connectors for up to three PCI expansion boards (one
full-sized and two half-sized 32-bit PCI slots).

TROUBLESHOOTING

This chapter contains troubleshooting information for the Compaq ArmadaStation EM.
Information on how to identify and correct some common hardware, memory, and
software problems is included. Troubleshooting information is covered on the following
topics:

■ Docking and undocking

■ Expansion board

Since symptoms can appear to be similar, carefully match the symptoms of the
computer malfunction against the problem description in the Troubleshooting tables to
avoid a misdiagnosis.

Follow these guidelines when troubleshooting:

■ Complete the recommended actions in the order in which they are given.

■ When the problem is resolved, stop performing the troubleshooting steps and do not

complete the remaining recommended actions.

■ Refer to Chapter 5 for any recommended removal and replacement procedures.

■ If the problem is intermittent, check the ArmadaStation EM several times to verify

that the problem is solved.

Before Replacing Parts

When troubleshooting a problem, check the following list for possible solutions before
replacing parts:

■ Verify that cables are connected properly to the suspected defective parts.

■ Verify that all required device drivers are installed.
