Installation Problems

By carefully following the installation procedures described in chapter
1, "Installing the HP AdvanceStack 10Base-T Hubs", you can avoid most
problems caused by improper installation of the hub or one of its
components.

Incorrect Installation

Incorrectly installing the hub, the HP Ethernet SNMP Module, or a
transceiver module can result in one or all of these components
malfunctioning or not functioning at all. If one or all of these
components appear to not be functioning, re-check the installation
procedure and, if necessary, re-install the component correctly.
If no power appears to be getting to the hub unit, check the power cord
at both the back of the hub and the ac power outlet to be certain the
cord is properly connected.

ASCII Console Connection Problems

The ASCII console was added to the HP J2603B Ethernet SNMP Module
firmware versions A.03.00 or later. If your EEPROM is older, you do not
have the ASCII console. See chapter 3, "Hub Reference" for information
on how to update your HP J2603A or B Ethernet SNMP Module with the
latest firmware.
You can determine your firmware version with HP Stack Manager or
HPInterconnect Manager. To determine your firmware version, follow
these steps:
1. In HP Stack Manager, double click on a hub that has an SNMP Mod-
ule.
2. Click on the Identify icon.
3. Scroll through the list until you see SNMP Agent EEPROM Vers.
