HP ProCurve 10Base-T Hubs
HP ProCurve 10Base-T Hubs
The HP ProCurve 10Base-T Hubs are a family of multiport repeaters. With
these hubs, you can connect computers, printers, and servers together for file
sharing. These hubs are compliant with the IEEE 802.3 Type 10Base-T
standard and support both 802.3 and Ethernet networks. The HP ProCurve
10Base-T Hubs follow these two standards by providing these features:
■lighting the hub’s port LED when it detects the connected device is
powered on and cable is good.
■retransmitting data that did not successfully arrive at the destination
device (collision detection).
A sample hub from the family is shown here to indicate common features.

HP ProCurve 10Base-T Hubs
Features
The following tables detail information about features on the HP ProCurve
10Base-T Hubs.
Feature Description
The following table provides descriptive information about features on the HP
ProCurve 10Base-T Hubs.
Table 1. HP ProCurve 10Base-T Hub Feature Descriptions
Feature Type Feature Description
Network Connections •12 or 24 twisted-pair ports to connect to end nodes or other
devices.
•An MDI/MDI-X (Media Dependent Interface) switch for Port 1
which allows you to connect either an end node (MDI-X position)
or to cascade a hub (MDI position) to the port, using a “straight-
through” twisted-pair cable in both cases. Port 1 has a factory
default of MDI-X, but can be toggled to an MDI state with the
adjacent push-button. All other ports are always MDI-X for
connection to computers and other end nodes through a twisted-
pair “straight-through” cable.
• An AUI/Xcvr slot for installing one of the HP Transceiver modules:
• HP Fiber-Optic Transceiver Module (HP J2606A) -- for 10Base-FL.
Allows you to connect your hub to a fiber-optic backbone.
• HP Twisted-Pair Transceiver Module (HP J2607A) -- for 10Base-T.
Adds another RJ-45 port for a total of 13 twisted-pair ports on the
J3300A and the J3301A hubs.
• HP ThinLAN Transceiver Module (HP J2608A)-- for 10Base2.
• HP AUI Port Module (HP J2609A) -- to attach external transceivers.
Easy-to-Use Design •Hub Status LEDs showing power, activity, collisions, fault and Xcvr,
each providing quick, easy-to-read hub status information and
troubleshooting help.
• Port Status LEDs showing transceiver and port status, providing
quick, easy-to-read port status information and troubleshooting
help.
•Metal brackets (included with the hub) that can be easily attached
to the hub for mounting the hub in a standard 19-inch telco rack or
on a rack. Also, table and wall mounting is supported.
Standards-Based
Compatibility
•IEEE 802.3 Type 10Base-T standard compatibility to support both
802.3 and Ethernet networks.

vi
HP ProCurve 10Base-T Hubs
•Advanced embedded SNMP agent code in both the HP J3301A
and HP J3303A, enabling these hubs to be managed remotely from
a network management station using SNMP over IP (using the
configured IP address). The agent code also provides HP EASE
(Embedded Advanced Sampling Environment), which samples
network data for enhanced diagnostics from a network
management station. Also, the hubs support the RMON MIB. The
HP J3301A and HP J3303A both can be managed in any of these
three ways:
– using a Simple Network Management Protocol application that
runs in Microsoft Windows and Unix (HP ASA).
– using a World Wide Web browser application that runs in
Netscape Navigator or Microsoft Internet Explorer (the
Browser Interface).
– using an ASCII Console Interface.
Reliable Operation •A self-test for fault identification when the hub is powered on or
when it is reset. (The hub can be reset from a network
management station or by pressing the Reset button.)
Other Features •Password setting capability on both the HP J3301A and HP
J3303A, enabling you to add and remove passwords, as needed,
for selective entry into the hub management environment.
Passwords can be set from a World Wide Web browser, a network
management station, through an ASCII Console session. If you
forget your password, and are locked out of the hub’s management
environment, you can remove the password by pressing the Clear
button.
•An RS-232 serial port on both the HP J3301A and HP J3303A that
provides out-of-band management access including:
– An ASCII console to configure, monitor, and troubleshoot the
hub.
– Variable baud rates on the hub’s out-of-band management RS-
232 port, and automatic sensing of the selected baud rate when
connecting to a terminal device.
– Full V.22bis modem line control for remote out-of-band
management access to the hub.
– Updatable firmware that enables enhancements to be
downloaded either from a computer attached to the out-of-
band management port via Xmodem or over the network via
TFTP.

Installing Your Hub
To install and configure your hub, you must complete six basic tasks. They are:
■locating and verifying the necessary parts
■installing a transceiver module
■connecting the hub to a power source
■mounting the hub
■connecting the hub to your network
1. Verify included parts
Each HP ProCurve 10Base-T Hub has the following components shipped with it:
■This manual. The HP J3301A and HP J3303A both come with the HP
ProCurve 10Base-T Hubs Management and Configuration guide
(5967-6862).
■A power cord, one of the following:
■accessory kit (5183-7210):
• bumper feet (4)
• bracket-to-rack screws 12-24 (7/16") (4)
• bracket-to-hub screws M4 (5/16") (4)
• mounting brackets for 44.55mm (1.75")-height hub (5183-1381)
2. Install the transceiver module
You may want to install the transceiver module and any external transceiver
you may want to attach to it before installing the hub. Transceiver modules
may require more lengthy protrusions created by the greater widths of the
different cables and connectors you may attach to a module (for example, an
Australia/New Zealand
Denmark
Europe
Israel
South Africa
Switzerland
United Kingdom
U.S./Canada/Mexico

external transceiver). Because of these widths, clearance in front of your hub
may be a factor in the placement of the device or stack that contains
protruding transceiver connectors, for example, a BNC connectors.
Inspect your installation site and identify whether enough room will be
available for the installed transceiver to be connected. Then see the guide that
shipped with your external transceiver for installation instructions. For HP
external transceivers, see the HP Recessed Transceivers Installation Guide
(p/n 5962-0066) for specific instructions.
Your transceiver modules can be one of the following:
■HP J2606A Fiber-Optic Transceiver Module
■HP J2607A Twisted-Pair Transceiver Module
■HP J2608A ThinLAN Transceiver Module
■HP J2609A AUI Port Module
3. Verify the hub operates correctly
Before mounting the hub, connect it to a power source and verify that the hub
will operate correctly.
1. Plug the power cord into the hub’s power cord receptacle and into an AC
power source.
Notes The hub does not have a power switch; it is powered on when the power cord
is plugged in.
Connect female end of included power cord
into male receptacle here and male end of
power cord to an alternating current power
source.

2. Check the LEDs on the hub’s front panel. When the hub is powered on, it
performs a power-on self test. See the table below for the LED self test
time that occurs during the self test. Note the upper number is for the HP
J3300A/HP J3302A and the lower number is for the HP J3301A/HP J3303A.
Figure 1-1. Self Test times for LEDs.
If the hub passes self test, the LEDs behave as described in the following
table. If the LEDs behave in a different way, the hub may failed self test.
See the LED operation table in chapter 2, “Troubleshooting” for a
complete description of the LED behavior.

Note that once you have connected cables to the hub, an AUI transceiver
LED or twisted pair Port LED stays on if link beat has been detected at
the port from an incoming device and the port is enabled. A Port LED turns
off if link beat is not detected.
When the self test completes successfully, the LEDs go into their normal
operational states. If a hub hardware fault exists, the hub will not
complete self test. This will be indicated by an abnormal LED pattern,
such as all port LEDs staying lit indefinitely. Note that the normal
operational state could include indefinitely blinking LEDs in the event of
a detected intruder. For managed HP ProCurve 10Base-T Hubs, see your
HP ProCurve 10Base-T Hubs Management and Configuration guide for
more information on Intruder Detection and flashing LEDs associated
with it.
If the self test time range elapses and the Fault LED continues to stay on
instead of turning off, the hub may have an error condition. If repeating
the self test does not correct the problem and the Fault LED still stays
continuously on, contact your HP authorized reseller for replacement
information. After the hub has passed its self test, you are ready to mount
the hub. Unplug the hub and proceed to the next step.
4. Mount the hub
Before mounting the hub, unplug it. The HP ProCurve 10Base-T Hubs can
be mounted in three ways:
1. in a rack or cabinet
2. on the wall
3. on a table
The hardware for mounting the hub is included in the accessory kit
(5064-2053) packed with the hub. See Appendix C, “Safety and Regulatory
Statements,” for general mounting precautions.
Rack or Cabinet Mounting
Warning The rack or cabinet should be adequately secured to prevent it from
becoming unstable and/or falling over. Please see Appendix C, “Safety
and Regulatory Statements,” for precautions and warnings associated with
rack mounting.

2. Position the hub in the rack or cabinet and slide it up or down until the
rack holes line up with the bracket holes.
3. Then attach the bracket to the rack with the No. 12-24 (7/16") screws and
black nylon washers included in the accessory kit with a Phillips Cross-
head No. 2 screwdriver. A flatblade screwdriver will also work in assem-
bling the hub to the rack. Make sure you have screws that fit your cabinet
or rack before mounting the hub.

Wall Mounting
Using a Phillips (crosshead) No. 2 screwdriver, attach the mounting brackets
to the hub with 8-mm (approximately 5/16") M4 screws included in the
accessory kit. Then attach the hub to a wood surface (minimum 1/2-inch
plywood or equivalent) with No. 12 (5/8") wood screws with a Phillips Cross-
head No. 2 screwdriver.
HP recommends that the bottom of the hub should be flush with the wall. The
brackets should be positioned at the front of the hub. The face of the hub
should be pointing up.
Note that the wood screws are not included in the accessory kit. Wood screws have
a pointed and for boring into the wood, unlike rack screws which are flat on the end.
Table Mounting
To place the hub on a table or other horizontal surface, no special tools are
necessary. Apply the four feet included in the accessory kit onto the bottom
of the hub. Be certain to pick a sturdy table in an uncluttered area. You may
want to secure the hub’s cables to the leg of the table to prevent people from
tripping over them.

5. Connect the hub to your network
Connect the hub to an AC power source. With the hub mounted, you are now
ready to connect the hub to your network. Typical hub connections are:
■hub-to-device connections. Connecting to network devices such as
computers, and printers.
■hub-to-hub and hub-to-switch connections. Connecting to another
Ethernet hub.
■hub-to-network backbones. Connecting to a network backbone.
This section describes the different ways you can connect your hub to your
network.
To connect a device to the hub, using unshielded twisted-pair (UTP) cable,
push the RJ-45 plug at one end of the cable into the RJ-45 jack on the hub until
the tab on the plug clicks into place.
