Avoiding Electrostatic Discharge

Sensitive components inside the base unit can be damaged by static electricity. To protect against this possibility, take the following precautions when working with internal components.
♦ Disconnect the base unit from AC power before opening the base unit. ♦ Touch the bare metal of the base unit chassis before touching any internal components. ♦ Handle all printed circuit boards as little as possible and only by the edges. ♦ Leave new parts in their protective packaging until you install them. ♦ Use a disposable or reusable antistatic wrist strap when servicing or upgrading the system.
Once you use a disposable wrist strap, you cannot use it again.
♦ Attach an antistatic wrist strap to any bare metal part of the base unit chassis. The metal
conductor in the elastic sleeve of a reusable antistatic strap must contact bare skin.

2 Upgrading the System

This chapter describes how to upgrade yo ur Zx1 rack-mount workstation by adding or replacing system components.
WARNING This is a user-serviceable system. Service and upgrade tasks should be
performed by users who can follow instructions in a manual to service equipment, and can do so without harm to themselves or damage to the equipment.

Before You Begin

WARNING The system is always on when connected to AC power. Before opening the
system, disconnect the system’s power cord from its AC power outlet.
WARNING Internal components may be at high temperatures. Allow time for them to cool
before handling them.
WARNING Internal components can be damaged by static electricity. Use an antistatic
wrist strap connected to the bare metal of the system’s chassis to protect against electrostatic discharge.
7
NOTE “Right side” and “left side” are as seen from the front of the system.
See Chapter 1, “Gaining Access to System Components,” for details on opening the system and protecting against electrostatic discharge.
These procedures assume you have removed the cover from the system.

Adding Memory

You can add system memory to the computer by adding or replacing dual inline memory modules (DIMMs). The system board has four DIMM sockets that can hold up to 1 GB of error-correction code (ECC) Synchronous Dynamic Random-Access Memory (SDRAM).
CAUTION System memory modules from Intergraph Computer Systems are certified for use
with Intergraph computers at extremes of temperatures and system load to ensure reliable performance. System memory modules available from other vendors may not function properly or reliably in your Intergraph computer.
8
Follow these population rules to correctly install DIMMs:
u
Install DIMMs one bank at a time.
u
Begin with bank 0 (nearest to the processor) or the first open bank, and end with bank 3.
The following tables show possible memory configurations. Each bank contains one socket.
Memory size
Configuration (ECC)
128 MB 16 x 72 256 MB 32 x 72
Memory
Bank 0 Bank 1 Bank 2 Bank 3
128 MB 128 MB 256 MB 128 MB 128 MB 384 MB 128 MB 128 MB 128 MB 512 MB 128 MB 128 MB 128 MB 128 MB
256 MB 256 MB
1,024 MB 256 MB 256 MB 256 MB 256 MB
See Chapter 3, “Servicing the System,” for instructions to install a DIMM. See the System Board Manual for DIMM socket locations.

Upgrading Processors

You can upgrade a single-processor system by adding another processor. When higher-speed processors become available, you can upgrade one- or two-processor systems by replacing the existing processors with faster processors.
Processors are mounted in a retention module that surrounds the processor slots. See Chapter 3, “Servicing the System,” and the System Board Manual for information on replacing a processor or adding a new processor.
Follow these rules when adding or replacing processors: ♦ When adding a processor to a single-processor system, the new processor must be the same
speed as the existing processor.
♦ When replacing dual processors with faster processors, both processors must be the same
speed.
♦ After installing faster processors, you must reinstall Windows NT on the system to ensure
proper operation with the new processors.

Adding Expansion Cards

You can install Accelerated Graphics Port (AGP), Peripheral Component Interconnect (PCI), non­compliant PCI, Industry Standard Architecture (ISA), and Plug-n-Play (PnP) expansion cards in the system. See below for a general description of these types of cards.
♦ AGP cards are graphics controllers that use the dedicated AGP interface for graphics
acceleration. AGP cards c‘ontain configuration registers that define resource information to the system during startup. AGP cards do not require manual system configuration when
installing the card. The system’s BIOS detects the board’s presence during startup and reads information from the board’s configuration registers to assign the necessary system resources.
♦ PCI cards contain configur ation registers t hat define resource information to the system during
startup. PCI cards do not require manual system configuration when installing the card. The system’s BIOS detects the board’s presence during startup and reads information from the board’s configur ation registers to assign the nec essary system resources.
♦ Non-compliant PCI cards do not contain configuration registers that allow the system to
automatically assign the necessary resources. These cards install in PCI slots, but you must configure the system’s BIOS to assign system resources before installing the card.
♦ Non-PnP ISA cards do not contain registers that define the resource information to the system
during startup. Therefore, you must configure the system’s BIOS to define the card to the system before installing the ISA card. This reserves system resources for the card.
9
♦ PnP cards are ISA cards that contain configuration registers like PCI cards. During startup,
the system’s BIOS automatically detects the installed card and assigns the necessary system resources. Since a PnP card is ISA-based, you install it in an ISA slot.
NOTE Assign system resources for any non-PnP ISA card and any non-compliant PCI
cards before installation. See the “Assigning System Resources” section below.
Each installed PCI card must draw less than 25 watts of power. The total allowable maximum wattage for PCI cards is 175 watts. The PCI slots are limited to 25 watts power dissipation per the Peripheral Component Interconnect Specification 2.1.
