HP J3128A AdvanceStack 10Base-T Hub-8E Bedienungsanleitung

Quick Setup Guide

for the HP AdvanceStack 10Base-T Hubs

Installation details are provided in the HP AdvanceStack 10Base-T Hubs Installation and

Reference Guide (5963-6554).

Install the Hub

1. Install optional add-in modules, for example an

HP Ethernet SNMP Module into the Expansion

Slot.

2. Plug the power cord into the hub’s receptacle

and into a properly grounded electrical outlet.

The hub does not have a power switch; it is

powered on when the power cord is plugged in.

Check the LEDs on the hub’s front panel. When

the hub is powered on, it performs

a 3 to 60 second self-diagnostic test. When the

test completes, the following occurs:

– Power LED is on.

– RPS LED is on if a Redundant Power Supply is

connected (available at the end of 1995).

– Fault LED is off.

– If an SNMP Module is installed, the Exp Slot

LED is on.

If the Fault LED stays on, the hub has

encountered an unrecoverable error. See

chapter 4, “Troubleshooting”.

4. Before mounting, unplug the hub.

5. Install the hub into a rack or cabinet following

pages 1-5 through 1-10 (in the accompanying hub

manual) and power the hub back on.

Hub-to-End Node Connection

1. Push the RJ-45 plug into the RJ-45 jack until the

tab on the plug clicks into place.

2. Push the other end of the cable into the LAN

adapter in the end node such as a PC, printer, or

print server.

Hub-to-Hub Connections

1. To connect the hub to another hub, push the

“crossover” cable RJ-45 plug into the RJ-45 jack

until the tab on the plug clicks into place.

2. Push the other end of the cable into the

connecting hub.

ThinLAN Backbone Connection

If you are connecting your hubs together on a

ThinLAN backbone, follow these steps:

1. Attach a ThinLAN cable section

to one side of a BNC “T”

connector.

2. Attach another ThinLAN cable

section or a 50-ohm terminator

to the other side of the “T”

connector.

3. Attach the “T” connector to the

ThinLAN port.

4. Cover the BNC connector

with an insulating cover.

Note: Each ThinLAN cable segment must be

terminated using a 50-ohm terminator at each end. In

the illustration above, a 50-ohm terminator would be

placed on one side of the BNC “T” connector if that

connector is at the end of the cable segment.
