PXES4P Switches
The connection procedure is straightforward. Simply insert the DC leads to the
PXES4PH's power terminals, positive (+) and negative (-) screws. The use of Ground
(GND) is optional; it connects to the PXES4PH chassis. Ensure that each lead is securely
tightened from the top, as shown here.
NOTE: Always use a voltmeter to measure the voltage of the incoming power supply
and figure out the +ve potential lead or -ve potential lead. The more +ve potential lead
will connect to the post labeled "+ve" and the rest to the "-ve".
The GND can be hooked up last.
When power is applied, the green PWR LED will illuminate.

3.8 Connecting Twisted Pair (RJ-45 ports)
The PXES4P Series Switches can be connected to only one media type with two
different speed i.e. 100BASE-TX and 10BASE-T. CAT 5 cables should be used when
making 100BASE-TX connections. When the ports are used as 10BASE-T ports, CAT 3
may be used. In either case, the maximum distance for unshielded twisted pair cabling is
100 meters (328 ft).
Media
Twisted Pair (CAT 3 or 5)
Twisted Pair (CAT 5)
NOTE : It is recommended that high quality CAT. 5 cables (which work for both 10 Mbps
and 100Mbps) be used whenever possible in order to provide flexibility in a
mixed-speed network, since PXES4P Series switch ports are auto-cross(MDIX)
for either 10 and 100Mbps. Note that the auto-cross function does not operate, if
the port is fixed or not supporting auto-negotiation.

Connecting Twisted Pair (RJ-45, CAT 3 or CAT 5, Unshielded or Shielded)
The following procedure describes how to connect a 10BASE-T or 100BASE-TX
twisted pair segment to the RJ-45 port. The procedure is the same for both unshielded and
shielded twisted pair cables.
1.
Using standard twisted pair media, insert either end of the cable with a RJ-45 plug
into the RJ-45 connector of the port. Note that, even though the connector is shielded,
either unshielded or shielded cables and wiring may be used.
2.
Connect the other end of the cable to the corresponding device.
3.
Use the LINK LED to ensure proper connectivity by noting that the LED will be
illuminated when the unit is powered and proper connection is established. If this
does not help, ensure that the cable is connected properly and that the device on the
other end is powered and is not defective.
4.
For Port # 1 or 1SW, if the LINK LED is not illuminated, move the switch which
has a cross-over or up-link for linking to another hub or Switch.
