Quick Installation
Hewlett-Packard’s Hub-12TX/Hub-12TXM models each contain
12 Fast Ethernet 100Base-TX, RJ-45 (MDI-X) ports, one MDI
cascade port, and one Expansion Slot for an optional connection
using 10/100TX and 100FX Switch Port Module.
The design built into the front display panel and configuration
options provides a friendly interface that simplifies installation
and network troubleshooting. If you are already familiar with
basic network operations, you should be able to install this hub
as described below:
1. Unpack the Hub-12TX/Hub-12TXM unit.
2. Find a location close to the network devices you need to
connect, and within easy reach of an electrical outlet.
3. Mount the hub on a desktop or any other flat surface. If you
are installing multiple hubs, you can stack them on top of
each other (after attaching the foot pads), or install them in a
standard EIA 19-inch rack. Note that these hubs do not
support wall mounting. See Chapter 2 for more details.
4. Connect any devices that use a standard 100Base-TX RJ-45
connector to the RJ-45 (MDI-X) station ports (for example,
a workstation, server, or router). Use 100
W Category 5
unshielded twisted-pair (UTP) or 100
W shielded twisted-pair
(STP) cable. Also be sure that the length of any twisted-pair
connection does not exceed 100 meters. (Refer to Chapter
2 for a more detailed description of calculating the maximum
cable length permitted between two end nodes.)
5. If you are stacking multiple hubs, connect the Stacking
Cable between the Stacking Ports (
Out and In), found on the
rear panel of the hub, on adjacent hubs. Run a simple chain
starting at the
Out port on the first hub, and ending at the In
port on the last hub. No more than five hubs can be
connected via the Stacking Cable.
