NTRODUCTION
The SuperStack™ II Entry Hub is a flexible unmanaged Ethernet repeater
which is very easy to use. It can be used in a variety of ways, from
building a small network to expanding a larger, more established
network.
The SuperStack II Entry Hub 12 Port TP (3C16440) has 12 dedicated
shielded twisted pair (TP) ports on the front panel. The SuperStack II
Entry Hub 24 Port TP (3C16441) has 24 dedicated shielded twisted pair
(TP) ports on the front 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 TP ports. A range of different media
Transceiver Modules is available from 3Com (see “ Products and Bulletin
Boards ” ).
The Entry Hub 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 Entry Hub can be powered either from the AC mains supply, or
through an optional 3Com SuperStack II Advanced RPS (Redundant
Power System). Contact your supplier for details.
The Entry Hub comes with:
■
One power cord for use with the Entry Hub
■
Four standard height and two reduced height self-adhesive
rubber pads
■
Mounting Kit
■
A Warranty Registration card for you to fill out and return
Network Connections
The Entry Hub can be used stand-alone or linked with other hubs.
Because each Entry Hub is a single IEEE 802.3 Ethernet repeater hub,
there can be a maximum of four Entry Hubs between any two pieces of
Data Terminal Equipment (DTE) (workstations or other equipment) on
the same network.
The Entry Hub is ready to use. You can connect the Hub to any 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 12 or 24 twisted pair segments to the
front of the unit.
The Entry Hub can use both shielded 150 ohm, and unshielded or
shielded 100 ohm 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 (328 feet). Consult your supplier's
technical support department if you need to use twisted pair cables
over greater distances.
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 ” ) to provide an additional 13th or 25th port.
You can connect the Entry Hub to any other 10BASE-T hub or unit using
port 12 or 24, to form an inter-repeater link. You must switch port 12 or
24 to MDI to bypass the internal cross-over normally implemented by
10BASE-T unit ports. See “ MDI Sw itch ” for information on connecting
hubs and switching port 12 or 24 between MDI and MDIX.
Repeater Functions
The Entry Hub has been designed to conform to the IEEE 802.3 Ethernet
standard for Local Area Networks, and provides all the standard
functions of an 802.3 repeater, including:
■
Signal retiming
■
Preamble regeneration
■
Fragment extension
■
Automatic partition/reconnection

Ports 1 to 11 (12 port hub) and 1 to 23 (24 port hub) are fixed as MDIX
ports so that they can be connected directly to DTE (workstations or
other equipment) which have MDI ports using normal ‘straight through’
TP cables.
Port 12 (12 port hub) and 24 (24 port hub) are switch selectable using
the MDI Switch. The ports can be MDIX ports (to connect directly to DTE

TP STATUS LEDs
The TP STATUS LEDs show the partition state of a port and whether or
not the Link Pulse signal is present on the segment connected to a port:
Green
Flashing
green
Off
If these checks do not identify the cause of a problem, it may be that the
Entry Hub or the device connected to the port is faulty. Contact your
supplier for further advice.
The Link Pulse signal is being received and the segment
attached to the port is functional.
The port is partitioned from the network.
■
Check the connections and the cable for any breaks in
the segment.
■
Make sure the transceiver attached to the DTE is
correctly connected and powered up.
■
Check for illegal 802.3 configurations, in particular,
loops.
If the cause of the partition is found and corrected, the
segment is reconnected automatically, after the first valid
packet is transmitted to, or received from the segment.
The Link Pulse signal is not being received.
■
Check that the attached DTE is switched on.
■
Check that the attached transceiver is not faulty.
■
If it is port 12 or 24 or an inter-repeater link, check the
setting of the MDI switch.
■
Carry out the checks recommended for when a
STATUS LED is flashing green.
■
Check for no more than 4 repeater stacks in series,
and that cable lengths do not exceed the maximum
specified in the standard for that medium.
Transceiver Module STATUS LED
If a Twisted Pair or Fiber Transceiver Module has been fitted, the LED
behaves the same as the TP STATUS LEDs, see 3 .
For other Transceiver Modules, the LED shows these states:
Green
Flashing
green
Off
Transceiver Module fitted correctly and not partitioned.
Transceiver Module partitioned.
Transceiver Module is faulty or fitted incorrectly.
A Transceiver Module port connected to a coaxial cable
segment may partition if the segment is incorrectly terminated.
The Transceiver Module port may partition if the SQE test pulse
is enabled on its transceiver. SQE test should be disabled on
transceivers used to connect 802.3 repeaters to the network.
Packet LED
The Packet LED flashes green whenever a packet is received on one of
the twisted pair ports or the Transceiver Module port.
If this LED does not flash, there are no packets being received by the
unit. If the unit is receiving packets but the LED does not flash, the LED
has failed . Contact your supplier.
Collision LED
The Collision LED flashes yellow when a packet collision has been
detected on a segment connected to one of the twisted pair ports or
the Transceiver Module port.
Under normal 802.3 Ethernet operation, collisions occur and cause the
Collision LED to flash. The probability of collisions increases during heavy
activity on the network. The Auto Partition/Reconnection function
partitions a segment from the rest of the network if more than
32 consecutive collisions are detected on that segment.
If the Collision LED lights for long periods of time, it indicates a high
amount of collisions which can slow your network down. If this happens,
you may need to separate parts of your network with a switch. Contact
your supplier.

Socket for Redundant Power System
Only connect a 3Com SuperStack II Advanced RPS (Redundant Power
System) to this socket. For details, follow the installation instructions in
the guide accompanying the Redundant Power System.
Transceiver Module Slot
A variety of 3Com plug-in Transceiver Modules or the Bridge
MicroModule can be installed in the Entry Hub (see “ Products and
Bulletin Boards ” ). Transceiver Modules provide direct network
connections to different media.
CAUTION: Do not remove the Transceiver Module blanking
plate while the hub is connected to a power source.
Ensure that SQE test is disabled on the Transceiver Module that you are
using.
To install a Transceiver Module, refer to the guide that accompanies it. If
you subsequently remove the Transceiver Module, you must replace the
blanking plate to aid the circulation of cooling air and prevent the entry
of dust and debris.
Self-adhesive Pads
The Entry Hub is supplied with four standard height and two reduced
height self-adhesive rubber pads. Usage of the feet depends on where
the Entry Hub is placed:
■
Use the four standard height pads if the unit is to be placed on a
flat surface or stacked with another SuperStack II product of the
same dimensions.
■
Use the two reduced height pads and two of the standard height
pads if the unit is to be stacked on a SuperStack II unit of different
dimensions — Line up the front of the units, and use the two
standard height pads at the front (to fit the recess of the unit
beneath) and use the two reduced height pads at the back.
Do not apply the pads if you intend to rack or wall mount the
hub.
If the hub is to be part of a free standing stack, apply the pads to each
marked corner area on the underside of the hub. Place the hub on top
of the lower unit, ensuring that the pads of the upper unit locate with
the recesses of the lower unit.
Positioning the Entry Hub
CAUTION: When installing the Entry Hub in a stack of different
size units, the Entry Hub must be installed below the narrower
units.
When deciding where to position the Entry Hub ensure:
■
It is accessible and cables can be connected easily.
■
Cabling is away from:
sources of electrical noise such as radios, transmitters and
■
broadband amplifiers.
power lines and fluorescent lighting fixtures.
■
■
Water or moisture cannot enter the case of the unit.
■
Air flow around the unit and through the vents in the side of the
case is not restricted (3Com recommend that you provide a
minimum of 25mm (1 inch) clearance).
To prolong the operational life of your units:
■
Never stack units more than six high if free standing, and ensure
that cables are supported so that they do not cause the stack to
fall over.
■
Do not place objects on top of any unit or stack.
■
Do not obstruct any vents at the sides of the case.
Rack or Wall Mounting
The Entry Hub can be mounted in a 19 inch equipment rack, or
wall-mounted using the Mounting Kit. See “ Mounting Kit Instructions ” .
