5HDG 7KLV )LUVW A prerequisite for using this manual to service Dell computer systems is a basic knowledge of IBM®-compatible PCs and prior training in IBM-compatible PC troubleshooting techniques. In addition to information provided in this manual and the User’s Guide that came with the system, Dell provides the Diagnostics and Troubleshooting Guide for troubleshooting procedures and instructions on using the Dell diagnostics to test the computer system.
&+$37(5 6\VWHP 2YHUYLHZ This manual contains field-servicing information for the Dell® OptiPlex® E1 Managed PC computer. The Dell OptiPlex E1 system is a high-speed (266 MHz), upgradable desktop computer built around an Intel® Celeron™ microprocessor. The OptiPlex E1 system uses a standard system board with an integrated NIC controller with Wakeup On LAN capability. The OptiPlex E1 system is available only in the low-profile desktop chassis (see Figure 1-1).
0DLQ 0HPRU\ Main memory for the OptiPlex E1 system ranges from a minimum of 16 MB to a maximum of 256 MB. All main memory is implemented using high-speed non-ECC DIMMs. One to two DIMMs, ranging in memory capacity sizes from 16 to 128 MB, may be used to provide a maximum memory capacity of 256 MB. 8SJUDGDEOH %,26 LQ )ODVK 0HPRU\ The system BIOS is implemented in flash ROM, which allows for easy BIOS upgrades using diskette files or files downloaded from Dell’s home page on the World Wide Web (www.dell.
NOTE: If the diskette drive and tape drive are both attached to the diskette drive controller on the system board, only the diskette drive is configured in the System Setup program as Drive A or Drive B. The tape drive is then listed as Not Installed (under either the Drive A or Drive B category). ,QWHJUDWHG 69*$ 6XEV\VWHP The OptiPlex E1 system includes an integrated high-performance 64-bit baseline AGP subsystem, implemented on the system board, which drives an external SVGA monitor.

The TAPI-compliant telephony input is a mono source with a maximum signal level of 2 Vrms. &KDVVLV ,QWUXVLRQ 'HWHFWLRQ The OptiPlex E1 system provides chassis intrusion detection. If the computer cover is removed, the Chassis Intrusion setting in the System Setup program changes from Not Detected to Detected and the following message is displayed during the boot routine at system start-up: Alert! Cover was previously removed.
)XOO 6HW RI , 2 3RUWV For desktop connectivity, the OptiPlex E1 system includes the following ports: 25-hole, bidirectional parallel port with EPP/ECP and demand-mode DMA support Two USB ports Two 9-pin serial ports Two PS/2 ports (mouse and keyboard) One 15-hole video connector One RJ45 Ethernet NIC connector Three audio jacks (microphone, line-in, and line-out) (optional) See Figure 1-3 for I/O port identifiers.

([SDQVLRQ &DUG 6ORWV The OptiPlex E1 computer has three expansion-card slots. The riser board has two ISA expansion-card connectors and two PCI expansion-card connectors. One PCI expansion-card connector and one ISA expansion-card connector share a single expansion-card slot, resulting in a total of three expansion-card slots (see Figure 1-4). The computer has a passive riser board, with no PCI-toPCI bridge.
