INSTALLATION Page 2-1 CHAPTER 2 INST ALLA TION 2.1 ADAPTER MODELS The E1100, E2100, and E3100 Series network adapters are used for the specific computer bus architectures listed below: • E1100 Serie.
Page 2-2 INSTALLATION 2.1.1 Model Number References The descriptions of Ethernet adapter features use model numbers with a lower case x in them. The x indicates that any number from the model number reference chart applies to that feature. The model number E11xx indicates an E1100 series adapter with any media combination has the described feature.
INSTALLATION Page 2-3 2.2.1 Unpacking the Adapter The network adapter and its software are shipped separately. The complete installation package should contain one conductive pouch with the adapter and this manual.
Page 2-4 INSTALLATION JP2 ROM Enable JP1 I/O Base Address Boot PROM Socket Figure 2-1. The E1112 Adapter 2.2.4 Preparing the E2100 for Installation The E21xx Series employs a socket for an optional Boot PROM. All parameters except the I/O base address and PROM base address are set through software.
INSTALLATION Page 2-5 2.3 SETTING THE I/O BASE ADDRESS JUMPER The I/O base address Jumper, JP1, must be set to one of four possible addresses before the adapter is installed. The I/O base address jumper sets the I/O (input/output) base address that identifies the adapter to the PC.
Page 2-6 INSTALLATION 2.4 I/O ADDRESS SPACE REQUIREMENTS The I/O address space for the E1100 and E2100 Series adapters occupies 20 Hex of the selected I/O base address. For example, if you select 220 Hex, the adapter I/O address range will extend through 23F Hex.
INSTALLATION Page 2-7 To install a Boot PROM, remove the Boot PROM from its packaging. Ensure that the legs of the Boot PROM are aligned in a 90 ° angle with the PROM body so the legs of the Boot PROM are perpendicular to the Boot PROM pin sockets.
Page 2-8 INSTALLATION • Carefully remove the adapter from its protective pouch, and visually inspect it. • Remove the backplate (2, Fig. 2-6) from the selected slot (3) by removing the screw (1) holding the backplate in place, and sliding the backplate out of the slot as shown in Figure 2-6.

INSTALLATION Page 2-11 Boot PROM Socket Figure 2-9. The E3112 Adapter 2.7.3 Installing the E3100 Adapter To install the adapter in your computer, follow these instructions: • Turn off the power to the PC and peripherals and disconnect all power cords and cables.
Page 2-12 INSTALLATION 1 2 1. Backplate 2. Thumbscrew Figure 2-10. Micro Channel Backplate Detail CAUTION: The adapter is sensitive to static discharges. Hold it by the corners. Avoid contact with the PC bus edge connector or any of the components. Failure to observe all static precautions may result in damage to the adapter.
INSTALLATION Page 2-13 • Align the adapter so the PC bus edge connector is lined up with the expansion slot (4) as shown in Figure 2-11. 1 2 3 4 5 Figure 2-11. Installing the E3100 Series Adapter • Slide the adapter into the guide slots and firmly press, but do not force, the adapter into the expansion slot.
Page 2-14 INSTALLATION 2.8 COPYING THE ADF FILE After an E3100 Series adapter is installed in your computer and before using it, you must copy the Cabletron Adapter Description File (ADF) onto a backup copy of your system’s Reference Diskette. The ADF is supplied with your Cabletron software.
INSTALLATION Page 2-15 2.10 TROUBLESHOOTING CHECK LIST FOR ADAPTERS • Make sure the adapter is installed and properly seated in the PC chassis connector. • On the adapter, if the coax port is used it is necessary to have a T and terminator attached to it.
Page 2-16 INSTALLATION • The adapters use shared memory. VGA adapters will use the A block through C7FFF. Memory adapters will use the entire D block. If you don’t have a memory adapter installed, the D block is your best selection - otherwise the C8000 starting address can be used on the standard memory adapters.
INSTALLATION Page 2-17 • The contents of the AUTOEXEC.BAT, CONFIG.SYS, PROTOCOL.INI, and NET.CFG files (if applicable). You can contact Cabletron Systems Technical Support by: Phone: (603) 332-9400 .

MAKING NETWORK CONNECTIONS Page 3-3 • Check the cable for continuity, and ensure that the cable is actually a twisted pair cable. • Check that the adapter is properly seated in the expansion slot. • Check that the twisted pair connection meets dB loss and cable specifications outlined in Section 3.
Page 3-4 MAKING NETWORK CONNECTIONS • Delay - Must not exceed 1000 nsec for a 10BASE-T link. This delay limits maximum link segments to 200 meters. • Crosstalk - Crosstalk is caused by signal coupling between cable pairs within a multi-pair cable bundle.
MAKING NETWORK CONNECTIONS Page 3-5 1 2 3 View B 4 1 2 3 5 View A Figure 3-3. Attaching a Thin-Net Segment 3.2.2 Thin-Net Requirements • Cable - Must be 50 ohm RG-58A type coaxial cable. • Length - Must be no longer than 185 meters (607 ft.). • Termination - A 50 ohm terminator at the far ends of each thin-net segment.
Page 3-6 MAKING NETWORK CONNECTIONS 3.3 CONNECTING TO A FIBER OPTIC LINK SEGMENT The physical communication link consists of two fiber optic strands between the adapter and the other Ethernet fiber optic device on the link: Transmit (TX) and Receive (RX).
MAKING NETWORK CONNECTIONS Page 3-7 Verify that the fiber strands are “crossed over” at the far end device, transmit to receive, by checking the labeling on each strand. Verify that the fiber connection meets the dB loss specifications outlined in Section 3.
Page 3-8 MAKING NETWORK CONNECTIONS • Length - The maximum fiber optic cable length is 2 km (6558 feet), if system budgets are met. However, IEEE 802.3 FOIRL (Fiber Optic Inter-Repeater Link) specifications specify a maximum of 1 km (3279 feet). 3.3.
