Upgrading the System
This chapter describes how to upgrade your
Zx
1
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.
NOTE
“Right side” and “left side” are as seen from the front of the system.
See Chapter 8, “Gaining Access to System Components,” for details on opening the system and
protecting against electrostatic discharge.
The procedures in this chapter assume you have already removed the left side panel from the
system.
Adding Expansion Cards
You can install Accelerated Graphics Port (AGP), Peripheral Component Interconnect (PCI), non-
compliant 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 contain 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.
