The SuperStack II Hub 10 24 Port TP
(3C16671A) has 24 dedicated twisted pair ports on the front panel and an AUI
port on the rear panel. The rear panel also has a slot for a 3Com Transceiver
Module or Bridge MicroModule; if fitted the Module will operate in addition to
the AUI port. A range of different media Transceiver Modules is available from
3Com (see"Products and Bulletin Boards").
The Hub 10 24 Port TP can be stand-alone or
linked with other Hub 10, LinkBuilder FMS II, FMS, 10BT or 10BTi units to form a
stack of units of different media. Each stack is the equivalent to a single IEEE
802.3 repeater, so stacking units gives you the benefit of a higher port count.
The Hub 10 24 Port TP is suited for office use where it can be wall-mounted,
rack-mounted, or free standing. Alternatively, the unit can be rack-mounted in a
wiring closet or equipment room. A mounting kit is supplied.
The Hub 10 24 Port TP can be powered either from
the AC mains supply, or through an optional 3Com Redundant Power System
(3C565047) to provide a more reliable supply. Contact your supplier for details.
Management:
A SuperStack II Hub 10 Management Module
(3C16630A) or Advanced RMON Module (3C16632) can be fitted to the Hub 10 24 Port
TP to provide full SNMP management, including statistics, resilient links and
security features. Only one Management Module or Advanced RMON Module is
required for each stack. Refer to the guides accompanying the module for details
on how to manage an Hub 10 unit or stack. Resilience and Security Hub 10
Management Module (3C16630A) and Hub 10 Advanced RMON Module (3C16632) offer
resilience and security features. Up to 16 resilient link pairs can be
configured via management software.
Network Connections:
You can connect the Hub 10 24 Port TP to any Data
Terminal Equipment (DTE) fitted with a 10Base-T network adapter or a 10Base-T
transceiver. Connect one end of the twisted pair cable to the RJ45 port on the
unit and the other end to the RJ45 port on your network adapter or transceiver.
You can attach up to 24 twisted pair segments to the front of the unit. The Hub
10 24 Port TP can use both shielded 150ohm, and unshielded or shielded 100ohm
twisted pair cables. To remain within 802.3 10Base-T rules the maximum length of
cable between the unit and any DTE should not be greater than 100m (110 yards).
Consult your supplier's technical support department if you need to use twisted
pair cables over greater distances.
You can connect any 802.3 transceiver to the unit
using an AUI cable connected to the AUI port on the rear panel. Also, you can
fit one of the 3Com Transceiver Modules or a Bridge MicroModule into the slot on
the rear panel (see"Products and Bulletin Boards").
You can connect the Hub 10 24 Port TP to any
other 10Base-T repeater using port 24, to form an inter-repeater link. You must
switch port 24 to MDI to bypass the internal cross-over normally implemented by
10Base-T unit ports: see "MDI Switch".
