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.
