HP AdvanceStack 100VG Hub-7E
At A Glance
The HP J3137A AdvanceStack 100VG Hub-7E is a high-speed multiport
repeater. With this hub, you can connect computers and other devices to-
gether in an unshielded twisted-pair cable network. This hub can be used to
upgrade your 10 Mbit/s Ethernet/IEEE 802.3 network that uses unshielded
twisted-pair cables to a 100 Mbit/s network.
Throughout this manual, this hub will be called the Hub-7E. The following
illustration shows the Hub-7E.
Features
Network Connections Six RJ-45 (twisted-pair) ports to connect to end nodes or other devices.
An Uplink port to cascade to another 100VG hub such as the following hubs:
HP J2413A AdvanceStack 100VG Hub-7M
HP J2410A AdvanceStack 100VG Hub-15
HP J2415A AdvanceStack 100VG Hub-14
Ethernet and Token Ring Support Support for both Ethernet and Token Ring framing. If you have 100VG LAN
adapters with 100VG Token Ring drivers, you can select the Token Ring position.
Remote Management An RS-232 port to connect an ASCII console for monitoring and troubleshooting
the hub and network.
Modular, Easy-to-Use Design LEDs showing power, activity, cascade, fault, and port status provide quick,
easy-to-read hub status information and troubleshooting assistance.
A small footprint that allows you to install the hub in a variety of ways, including
on a desk, under a desk, or on a wall.
Standards-Based Compatibility Compatible with the IEEE 802.12 standard.

2. Verify that the Hub Works
Your hub uses power from an external DC power supply. To provide power
to the hub, follow these steps:
1. Plug the DC power supply into the hub’s Power connector.
Note If your installation requires a different power cord than the one supplied
with the hub, contact your HP-authorized LAN dealer or your local
HP sales office.
2. Plug the power cord into the power supply.
3. Plug the power cord into an AC power source. When installing the
Hub-7E, note that the AC outlet must be located near the equipment
and should be easily accessible.
Note The hub does not have a power switch; it is powered on when the power
cord is plugged in.

4. Check the LEDs on the hub’s front panel.
When the hub is powered on, it performs a self-diagnostic test.
During the test, watch the LEDs on the front of the hub for the
following to occur:
At Power On All LEDs turn on.
During Self-Test Self-test requires about 3 seconds. While the hub is tested,
half of the LEDs are momentarily turned on and off. Then the
remaining LEDs are momentarily turned on and off.
After Self-Test All LEDs are off except:
Power LED is on,
Twisted-Pair ports reflect their normal operating state.
If the Fault LED stays on, the hub has failed its self-test. See page 7
for information about diagnosing your hub.
5. After the hub has passed its self-test, you are ready to mount the hub.
Before mounting the hub, unplug it.
3. Mount the Hub
The Hub-7E can be placed on a desk or mounted on any vertical or horizon-
tal surface, for example a wall or under a desk.
Equipment Required
To mount the hub on a wall or under a desk, you will need the mounting
hardware listed on page 2, and a Phillips screwdriver.
Mounting
Precautions Before mounting the hub, follow these mounting precautions:
Plan the hub’s location and orientation relative to other devices and
equipment. Also consider the cabling that will be attached to the hub
and ports that will be used. In the front of the hub, leave 3 inches
(7 cm) of space for twisted-pair cables. In the back of the hub, leave
3 inches (7 cm) of space for the AC power cord.
Ensure that the HP AdvanceStack hub(s) do not overload the power
circuits, wiring, and over-current protection. To determine the
possibility of overloading the supply circuits, add together the
amperage ratings from the nameplates of all your hubs (and other
equipment) installed on the same circuits and compare the total with
the rating limits for the supply circuits.
