2.3 PXES4P Series, with four (RJ-45) Copper ports
The PXES4P Series chassis house one main PC board. The power supply is an
external AC unit or internal DC via a screw terminal block. The front side of the chassis
has three twisted-pair switched ports and one port is provided on the rear side. All four
18
PXES4P Switches
Installation and User Guide (10/06)
ports of the PXES4P Series convenient switch support auto-cross (MDIX), and perform the
auto-cross in the auto-negotiation mode only.
Dual LEDs indicating the operating status of ports are mounted on the top as well
as end for convenience and may be viewed from any direction. There are power (PWR)
indicators for the unit to validate that the unit is turned ON. For each port, there are Link
and Activity (LK/ACT) LEDs indicating traffic that are mounted on the top of the unit as
well as the end. LEDs mounted next to each port indicate (LK/ACT as LA1, LA2, LA3,
LA4), 10/100 (ON for 100Mbps), and full/half duplex (F/H is ON for full duplex).
The DC power plug connector or “jack” is in the right rear of the chassis. The
internal DC input terminal block is also provided on the rear side of the unit.

2.4 Frame Buffering and Latency
The PXES4P Series Switches are store-and-forward switches. Each frame (or
packet) is loaded into the Switch’s memory and inspected before forwarding can occur.
This technique ensures that all forwarded frames are of a valid length and have the correct
CRC, i.e., are good packets. This eliminates the propagation of bad packets, enabling all of
the available bandwidth to be used for valid information.
While other switching technologies such as "cut-through" or "express" impose
minimal frame latency, they will also permit bad frames to propagate out to the Ethernet
segments connected. This "cut-through" technique permits collision fragment frames,
which are a result of late collisions, to be forwarded which add to the network traffic.
Since there is no way to filter frames with a bad CRC (the frame must be present in order
for CRC to be calculated), the result of indiscriminate cut-through forwarding is greater
traffic congestion, especially at peak activity. Since collisions and bad packets are more
20
PXES4P Switches
Installation and User Guide (10/06)
likely when traffic is heavy, the result of store-and-forward operation is that more
bandwidth is available for good packets when the traffic load is greatest.
When the Switch detects that its free buffer queue space is low, the Switch sends
industry standard (full-duplex only) PAUSE packets out to the devices sending packets to
cause “flow control”. This tells the sending devices to temporarily stop sending traffic,
which allows a traffic catch-up to occur without dropping packets. Then, normal packet
buffering and processing resumes. This flow-control sequence occurs in a small fraction of
a second and is transparent to an observer. See Section 4.6 for additional details.
Another feature implemented in PXES4P Series Switches is a collision-based
flow-control mechanism (when operating at half-duplex only). When the Switch detects
that its free buffer queue space is low, the Switch prevents more frames from entering by
forcing a collision signal on all receiving half-duplex ports in order to stop incoming traffic.
21
PXES4P Switches
Installation and User Guide (10/06)
The latency (the time the frame spends in the Switch before it is sent along or
forwarded to its destination) of the PXES4P Series Switches varies with the port-speed
types. The length of the frame is a variable here as it is with all store-and-forward
switches. For 10 Mb-to-10 Mb or 10 Mb-to-100Mb or 100Mb-to-10 Mb forwarding, the
latency is 15 microseconds plus the packet time at 10 Mb. For 100Mb-to-100Mb
forwarding, the latency is 5 microseconds plus the packet time at 100Mb.

This section describes the proper connection of the -48VDC leads (or 24VDC,
12VDC leads) to the Direct DC power terminal
block on the PXES4P hardened media converter (as
shown in Figure above). The DC terminal block on
the PXES4P is located on the left side of the unit
and is equipped with three (3) screw-down lead
posts. The power terminals are identified as positive
(+) and negative (-), and they are floating inside the unit so that the user if desired may
ground either of the terminals. The chassis is “earth” or ground (GND).
33
PXES4P Switches
Installation and User Guide (10/06)
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).

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.

Connections to NICs which support Auto-Negotiation, RJ-45 ports
The copper ports of PXES4P Series Switches will function properly with NICs
(Network Interface Cards) which support Auto-Negotiation, and the Fast Link Pulse (FLP)
coding for the 100BASE-TX signaling system. When connecting a NIC to the PXES4P-
Sereis, it may be necessary to reload the NIC drivers on the user device if the NIC has been
communicating with a protocol other than 100BASE-TX (such as 10BASE-T). When
100Mb operation is agreed and in use, the 10/100 LED is illuminated steady ON and is
OFF, if 10 Mbps traffic.

4.0 OPERATION
Installation and User Guide (10/06)
4.1 Dual-Speed Functionality, and Switching The PXES4P Series Switches provide
four switched ports (three ports in the front and one on the rear). The architecture supports
a dual speed switching environment, with auto-negotiation capability.
The switched RJ-45 ports are full-duplex and auto-sensing for speed. (See section
2.2). When the connected device is 10 Mbps, the PXES4P obeys all the rules of 10 Mbps
Ethernet configurations. The 10 Mbps users share a 10 Mbps traffic domain, and can
“communicate with” 100Mbps users as well as 100Mbps domain. Similarly, the 100Mbps
traffic obeys the rules of 100Mbps Ethernet, and can communicate with 10 Mb domain too.
PXES4P Series is plug-and-play device. There is no software configuring to be
done at installation or for maintenance. The internal functions of both are described below.
38
PXES4P Switches
Installation and User Guide (10/06)
Switching, Filtering and Forwarding
Each time a packet arrives on one of the switched ports, the decision is taken to either filter
or to forward the packet. Packets whose source and destination addresses on the same port
segment will be filtered, constraining them to one port and relieving the rest of the network
from processing them. A packet whose destination address is on another port segment will
be forwarded to the appropriate port, and will not be sent to the other ports where it is not
needed. Packets needed for maintaining the operation of the network (such as occasional
multi-cast packets) are forwarded to all ports.
The PXES4P Series Switches operate in the store-and-forward switching mode,
which eliminates bad packets and enables peak performance.
39
PXES4P Switches
Installation and User Guide (10/06)
Switching, Address Learning
The PXES4P Series units have address table capacity of 2K node addresses, and
are suitable for use in large networks. They are self-learning, so that as nodes are added or
changed, the PXES4P Series automatically keeps up with node locations.
An address-aging algorithm causes least-used addresses to fall out in favor of new
frequently-used addresses. To reset the address buffer, cycle power down-and-up.
4.2 Auto-cross (MDIX), Auto-negotiation and Speed-sensing
The RJ-45 ports support auto-cross (MDI or MDIX) in the auto-negotiation
mode according to the IEEE 802.3u standard. No crossover cables are needed when
connecting the PXES4P to other unmanaged switches, legacy hubs, managed switches,
media-converters etc. Please note that there can be conditions with managed switches
where the switch manager fixes the port settings via software, and the result of the
auto-negotiation is changed in the managed switch by the manager commands. In such
40
PXES4P Switches
Installation and User Guide (10/06)
cases, the 10/100 speed or the F/H mode may be affected, but auto-cross in the
PXES4P Switches will still work. The auto-cross function cannot be disabled.
When an RJ-45 cable connection is made, and each time LINK is enabled,
auto-negotiation takes place (except for legacy products, which do not have auto-
negotiation and which go to the default state accordingly). The Switch advertises its
capability for 10 or 100 Mbps speed and F/H duplex mode, and the device at the other
end of the cable should similarly advertise / respond. Both sides will agree to the speed
and mode to be used per the IEEE 802.3u standard. Depending upon the devices
connected, this will result in agreement to operate at either 10 Mbps or 100Mbps speed,
and full- or half-duplex mode.
