Installing the Workgroup EISA HP

Adapter Hardware

This chapter explains how to install the workgroup EISA HP single

attachment and dual attachment adapters in HP Apollo workstations, connect

the cables, check the LEDs, and conﬁrm the network connections.

Installation Overview

To install the EISA HP adapter, make sure you complete the following

procedures and have the required tools available. See Chapter 2, “Preparing

for Installation.”

• Turn off the power to the workstation after following normal software

shutdown procedures.

• Remove the system cover.

• Install the EISA HP adapter.

• Replace the system cover.

• Connect the CDDI or FDDI cables.

• Apply power to start up the workstation.

Installing the EISA HP Adapter

This section provides general instructions for installing the EISA HP single

attachment or dual attachment adapters in an HP Apollo workstation.

Included are brief instructions to follow for Model 720, 730, and 750

workstations. For speciﬁc instructions for these and other models, refer to HP

Apollo Model 7xx Owner’s Guide for HP-UX Users, which is provided with

your workstation.

Caution Make sure that your workstation is powered down before

you begin this procedure.

Chapter 4 Installing the Workgroup EISA HP Adapter Hardware This chapter explains how to install the workgroup EISA HP single attachment and dual attachment adapters in HP Apollo workstations, connect the cables, check the LEDs, and confirm the network connections. Installation Overview To install the EISA HP adapter, make sure you complete the following procedures and have the required tools available. See Chapter 2, “Preparing for Installation.

Inserting the EISA HP Adapter Once you have removed the workstation’s top cover and located an available bus-master EISA slot, you can insert the EISA HP adapter. Models 720 and 730: remove the EISA interface assembly at the rear of the workstation. Remove the five screws, and pull the handle to remove the assembly. See Figure 4-1.

Step 2 Model 750: unscrew the knob to remove the top and side covers. Push down on the top of the radio frequency interference (RFI) shield to release the top tabs. Pull the shield up and away from the workstation to release the bottom tabs. See Figure 4-2. H2361 Top tabs RFI shield Side cover Bottom tabs RFI shield Figure 4-2 Model 750 Cover and RFI Shield Removal Step 3 Remove the slot cover(s) to expose the desired EISA slot(s). Use the slot cover screws to secure the adapter.

Step 4 Without touching any electrical components, slide the adapter into the slot. Press firmly into place. See Figure 4-3. Retaining screw H2360 Retaining screw Model 720/730 Model 750 Figure 4-3 Inserting the EISA Adapter in the EISA Slot Step 5 Secure the adapter with the screw that held down the slot cover. Step 6 Reassemble the system. Connecting the Cables Connect the EISA HP adapter to the network as follows: Step 1 Connect one end of the network cable to the EISA HP adapter port.

Note You must install the EISA HP adapter driver and utilities before your workstation is logically connected to the network. Connecting to a Bypass Switch (FDDI only) You can connect an optional bypass switch to maintain connectivity to the FDDI ring. If a station enters a fault condition or is powered down or rebooted, the ring will not wrap if a bypass switch is present on the faulty station. Figure 4-4 shows how the bypass switch connects to the network and dual attachment adapter.

Ringop LED Verify connection to the ring by observing the ringop LED. In a single attachment configuration, the ringop LED monitors ring operation. If this LED is on, the adapter is connected to the CDDI/FDDI ring. In a dual attachment configuration, the ringop LEDs on the dual attachment adapter provide a visual indication of the state of your network. The ringop LED information in Table 4-1 will help you determine if your network is functioning properly.

Verifying the Installation You can verify the installation of your EISA HP adapter by viewing the startup information. The following text shows an example of the information you can expect to see. Note Information shown as boldface screen font in the following example confirms the EISA HP adapter driver installation. Mar 23 16:50 Beginning I/O System Configuration. Block TLB entry #5 from 0xf9000000 to 0xf9ffffff allocated. HPA1924A Bit-Mapped Display (revision 8.

Confirming IP, Netmask, and Broadcast Addresses After installing the adapter driver and hardware, use the ifconfig, ping, and fddistat commands to display EISA HP adapter driver confirmation information. Following are examples of the ifconfig and ping commands. See Appendix C, “Using the FDDI Status Utility,” for examples of the fddistat command.
