The Basic DECstation 5000 Model 100 Series Workstation

The DECstation 5000 Model 100 Series includes three

workstations: the Model 120, the Model 125, and the Model

133. The nameplate on the front of the system unit shows

which model you have.

Nameplate

Figure 1-1. Typical DECstation 5000 Model 100 Series workstation

The only difference between the three models is the central

processing unit (CPU) module. The CPU in the Model 120

workstation operates at a speed of 20 megahertz (MHz), the

CPU in the Model 125 operates at a speed of 25 MHz, and the

the CPU in the Model 133 operates at a speed of 33 MHz.

photocopiers, and other sources of heat. – Protect your workstation from direct sunlight. Allow air to ﬂow freely around your workstation to keep

heat from building up and damaging your equipment. – Leave 4 inches (10 centimeters) of space between

system unit vents and other objects. – Leave 3 inches (7.6 centimeters) of space between

monitor vents and other objects.

Humidity

Keep relative humidity within the range of 10 to 80 percent.

Cleanliness

Keep your work area as dust-free as possible.

Interference

Set up your workstation at least 30 inches (76.2 centimeters) away from other terminals or monitors and from other sources of electrical interference, such as printers or electric pencil sharpeners.

Limit exposure to static electricity and magnetized objects by setting up your workstation away from busy corridors and other high-trafﬁc areas and away from ﬁling cabinets and steel beams in walls.

Attaching a SCSI Terminator to the Base System SCSI Connector

A connector for a small computer system interface (SCSI) is built into the base system hardware, as shown in Figure 2-1, on page 2-2. When the connector is not connected to a SCSI device (a disk drive or other device that uses a SCSI interface), it must be terminated with a SCSI terminator. Otherwise, the workstation may not function properly.

For the time being, put a SCSI terminator on the SCSI connector on the system unit. You can remove the terminator later if you connect SCSI devices to the system unit.

Your system unit may have additional SCSI connectors in option slots. Do not attach SCSI terminators to these connectors.

Ethernet Hardware for the Basic

Workstation

This chapter explains how to connect ThickWire Ethernet loopback connectors to all ThickWire Ethernet connectors on the system unit. Ethernet is a standard set of conventions or rules for network communications. A network is a group of computers and other communications devices that are linked together.

Ethernet Hardware for the Basic Workstation 3–1

Page 51

Installing ThickWire Ethernet Loopback Connectors

A ThickWire Ethernet connector is built into the base system hardware, as shown in Figure 2-1, on page 2-2. If your workstation is equipped with the TURBOchannel options, you have additional ThickWire Ethernet connectors in the TURBOchannel option slots. All of the connectors must be either connected to an Ethernet cable or closed with a loopback connector.

For the time being, put a loopback connector on every ThickWire Ethernet connector on the system unit. You can remove the loopback connectors later, when you connect the workstation to your networks. See Chapter 6, section ‘‘Connecting the Workstation to a ThickWire Ethernet Network’’, on page 6-3 for an explaination on how to connect to a network.

To Install ThickWire Ethernet Loopback Connectors

1. For each ThickWire Ethernet connector on the system unit,

ﬁnd the square ThickWire Ethernet loopback connector that came with your workstation.

2. Hold the loopback connector so that the widest part of the

connector is on top.

3. Firmly press the loopback connector onto the ThickWire

Ethernet connector on the system unit.

Installing and Removing Memory

DECstation 5000 Model 100 Series workstations use pairs of 2-megabyte or 8-megabyte memory modules. Your workstation can hold up to eight pairs of memory modules.

The system unit comes with at least four 2-megabyte MS01-AA or MS01L-AA memory modules or two 8-megabyte MS01-CA memory modules in place.

With pairs of 2-megabyte MS01-AA or MS01L-AA memory modules, you can install up to 32 megabytes of memory.

With pairs of 8-megabyte MS01-CA memory modules, you can install up to 128 megabytes of memory.

The cnfg command shows how much memory is installed in your workstation. Chapter 11 explains how to use the command.

To Install Memory Modules

Use either 2-megabyte or 8-megabyte memory modules in your workstation. The MS01-AA and the MS01L-AA can be used interchangably.

Caution: Do not mix 2-megabyte and 8-megabyte memory modules in

the same system. This will cause the 8-megabyte modules to act as 2-megabyte modules.

You need a medium Phillips screwdriver.

Installing and Removing Drives in the System Unit

You can install drives in three places in your workstation:

In the base of the system unit In the front drive panel of the system unit In expansion boxes that can be connected to the system

unit

To install hard disk drives in the base of the system unit, turn to the section ‘‘To Install a Drive in the System Unit’’, on page 5-28. Hard disk drives are drives in which the recording media are disks fastened permanently inside the drive.

To install removable media drives in the front drive panel, turn to the section ‘‘To Install a Removable Media Drive Inside the System Unit’’, on page 5-42. Removable media drives are drives where the recording media are disks and tapes that you can remove and insert as you need them. Diskette drives and tape drives are examples of removable media drives.

Understanding SCSI ID Numbers

The workstation distinguishes each internal and external drive connected to a small computer system interface (SCSI) connector by the SCSI ID number (0 to 6) assigned to that drive.

Each drive comes from the factory with a SCSI ID number already set. These factory settings, called default settings, are listed in Table 5-1.

Table 5-1. Default SCSI ID Numbers for Internal Drives

Drive Type Default Setting

RZ23L Hard disk 2 (and 3)* RZ24 Hard disk 2 (and 3)* RZ25 Hard disk 2 (and 3)* RRD42 Compact disc drive 4 RX23 Diskette drive 5 RX33 Diskette drive 5 TZK10 Tape drive 5 * If the system contains two RZ23L, RZ24, or RZ25 drives, the ID numbers

are preset to 2 and 3 at the factory.

Setting the SCSI ID numbers on your drives

Each drive within a group (or chain) of drives must have its own unique SCSI ID number (0 to 6), in order to function properly.

To avoid the problem of duplicate SCSI ID numbers within the same group, don’t use more than one drive that has the same default setting.

To check for duplicate SCSI ID numbers, you must examine the settings on your drives, as shown in Appendix D of this guide.

Internal Hardware Options 5–27

To Install a Drive in the System Unit

All internal hard disk drives are installed in the same way.

1. Unpack the hard disk drives.

2. Follow the instructions that came with your worksystem

software to shut down the software.

3. Type cnfg 3 and press Return. The workstation displays

the conﬁguration for the base system hardware and any previously installed SCSI drives.

The following example of a cnfg display shows no drives or other options connected to the base system unit (which is represented by the

can choose 0, 2, 3, 4, 5, or 6, because the only number

in the device codes is 1. In this example, assume that

we chose 2.

c. Write down the new number on the same paper where

you wrote the device codes.

2. Use a pair of needle-nose pliers to set the SCSI ID on

the drive that you are installing. Set the ID to the new number that you chose by arranging the SCSI switches or jumpers to indicate the number. Jumpers are small rectangular collars that ﬁt over the ID pins on drives and other components. If your drive uses jumpers, the jumpers are already on the pins, and you have to arrange them appropriately.

In Appendix D, Figures D-1 through D-7 show how to arrange the jumpers on each hard disk drive. They also show the connectors for the power supply and SCSI cables.

Fasten the hard disk drive in the system unit

1. Look inside the drive bracket on the front drive panel.

If the end of the SCSI cable is fastened to the drive

bracket with a tie-wrap, cut the tie-wrap.

If the power supply cable and SCSI cable are tucked

inside the bracket, pull them out carefully.

If there is a drive in the drive bracket, leave the cables

attached to the drive.
