Activity Lights

The ArmadaStation has two activity lights.

MultiBay Activity Light

The MultiBay activity light is located on the MultiBay. This light turns on when information from a removable drive inserted in the ArmadaStation MultiBay is accessed.

Power/Suspend Light

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

MultiBay

The ArmadaStation features a MultiBay. This MultiBay, along with its release latch, is removable as a unit. The MultiBay is located in the front of the ArmadaStation base assembly and secured by the drive cages, drive cage shield, and upper case assembly. The MultiBay supports the same drives that are used in the computer MultiBay and can be used to charge batteries.

The ArmadaStation MultiBay supports the following devices:

■CD-ROM drive

■Second hard drive

■Second battery pack

■Diskette drive

Compaq LTE Elite and LTE 5000 hard drives that are configured for use as secondary drives can be used in the ArmadaStation MultiBay. A hard drive must be inserted in an Armada 7000 Hard Drive MultiBay Adapter before it can be inserted in a MultiBay.

The system (computer and ArmadaStation) must be turned off when inserting or removing a hard drive, diskette drive, or CD-ROM drive from the MultiBay. The system does not have to be turned off when inserting or removing a battery pack.

Half-Height Bay

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

1-8 Introduction

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Security Lock

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

NOTE: The PC Card security post must first be put in place before the security lock will prevent PC Cards from being removed from the ArmadaStation.

PC Card Slots

The ArmadaStation has two PC Card slots. The slots support one of the following PC Card combinations:

■Two Type I or Type II PC Cards

■One Type III PC Card in the top slot and a Type I or Type II in the bottom slot. If a Type III PC Card is inserted in the bottom PC Card slot, no other PC Cards can be used.

The PC Card slot supports both 5-volt and 3.3-volt PC Cards in accordance with the PC Card Standard and the Exchangeable Card Architecture (ExCA) Specifications 1.10.

NOTE: Many cards on the market do not comply with PC Card specifications and, therefore, do not function properly in the computer. To assist in selecting compatible PC Card devices, Compaq provides a list of third-party cards that have been tested in Compaq products. To ensure compatibility, select a PC Card from the Compaq PC Card Solutions List. Call Compaq Reseller Support to have a copy of the list faxed to you.

The only serviceable part of the PC Card slots is the slot door. The rails and connectors are incorporated into the I/O board.

Chapter 2

Troubleshooting

This chapter contains troubleshooting information for the ArmadaStation and Armada MiniStation. 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

■Network

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 Chapters 5 and 6 for any recommended removal and replacement procedures.

■If the problem is intermittent, check the ArmadaStation or Armada MiniStation 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.

Solving Network Problems

This section provides guidelines for troubleshooting common Ethernet network problems. Refer to these guidelines when you have determined that the computer is not communicating with the network when docked in the ArmadaStation or Armada MiniStation. These guidelines do not discuss the process of debugging the network cabling.

The following are some common problems to check first. Refer to the table below for additional problems and solutions.

■Ensure that the cabling is securely attached to the ArmadaStation or Armada MiniStation. A loose cable is the most common cause of network problems. If the cable is loose, secure it and determine if the computer can communicate with the network.

■Determine whether the current computer or another computer has communicated with the network from the ArmadaStation or Armada MiniStation. If so, determine whether anything was added or changed that could have stopped the network interface from working.

■Run Diagnostics before installing the network drivers to verify that the network interface is working correctly.
