Fast Ethernet Network Configuration Rules
To remain within IEEE 802.3 100 Mbps Fast Ethernet rules, the maximum
length of cable between the Baseline Dual Speed Hub and an attached
device must not exceed 100 m (328 ft). Ensure that there are no more
than two 100 Mbps hubs between any two devices on your network, and
that the total cable distance (A+B+C) between the two devices does not
exceed 205 m (672.4 ft), as shown below.
If you connect two Baseline Dual Speed Hubs together, the link
between them operates at 100 Mbps.
2MDISwitch
This switch affects port 12 (3C16592B) or port 24 (3C16593B). Ports 1–11
(3C16592B) or 1–23 (3C16593B) are fixed as MDIX ports. Each can be
connected to a device with an MDI port (such as most workstations) using
a normal “straight through” TP cable. Port 12 or 24 is “switch selectable”
using the MDI switch:

To connect the hub to a 10 Mbps or 100 Mbps unit, connect an MDIX
port on the unit to port 12 or 24 on the Hub, as shown above. Ensure
that the MDI switch on the Hub is in (MDI). If an MDI/MDIX port is used
on the other unit, ensure that the MDI switch for that port is out (MDIX).
Alternatively, you can use “cross-over” TP cable to connect any MDIX port
on the Baseline Dual Speed Hub to any MDIX port on another unit.
For normal redundancy, the ARPS requires one Type 1 Power Module (part
number 3C16072). For full redundancy, the unit requires two Type 1
Power Modules combined using a Type 1 Y-Cable (part number 3C16079).

height and four full height.
You do not need to apply the pads if you intend to rack mount
the unit.
If you are placing the units one on top of the other, you must use the
self-adhesive rubber pads supplied. Apply the pads to the underside of
each unit, sticking one in the marked area at each corner. Place the units
on top of each other, ensuring that the pads of the upper unit line up
with the recesses of the lower unit. Use the two thinner pads when
stacking the unit with a narrower one above.
Positioning the Baseline Dual Speed Hub
CAUTION: When installing the Baseline Dual Speed Hub in a
stack of different size units, the Baseline Dual Speed Hub must
be installed above any larger units. Do not have a free standing
stack of more than six units.

or exhibits a defect in materials or workmanship within the first forty-eight (48)
hours of installation but no later than thirty (30) days after the date of purchase, and
this is verified by 3Com, it will be considered dead- or defective-on-arrival (DOA) and
a replacement shall be provided prior to 3Com receiving the defective product, but
only if Customer provides a purchase order number, credit card number, or other
method of payment acceptable to 3Com, to be used if 3Com needs to charge
Customer for the replacement, as explained below. The replacement product will

of the DOA product, but may be delayed due to export or import procedures. The
shipment of a replacement product prior to 3Com receiving the defective product is
subject to local legal requirements and may not be available in all locations. When
such a replacement is provided and Customer fails to return the original product to
3Com within fifteen (15) days after shipment of the replacement, 3Com will charge
Customer for the replacement product, at list price.

provided for five (5) years, after which time it may be available for a specified fee,
but in either case only if Customer provides a purchase order number, credit card
number, or other method of payment acceptable to 3Com, to be used if 3Com
needs to charge Customer for the replacement, as explained below. 3Com will make
