Two sets of LEDs to indicating the operating status of ports are mounted on the
top and front (for extra viewing advantage while rack-mounted). For each port, there are
Link and Activity (LK/ACT) LED’s on the top indicating that the media cables are
connected correctly and showing, by blinking, when there is traffic. The LK/ACT LED’s
are repeated on the front as LA1 (port 1), LA2 (port 2), and LA3 (port 3). There is a power
(PWR) indicator on the front of the unit to validate that the unit is turned ON.
The single fiber port on the LBH110’s is multi-mode with an ST connector and ,
on the LBH100’s, it is an SC, ST or small form-factor connector (MTRJ multi mode or LC
single-mode). The Full Duplex/Half Duplex (“F- H”) manual switch provided underneath
the fiber port allows the user to fix the fiber port at Full or Half Duplex mode as required.
The external DC power plug connector and/or “jack” and the internal DC input
terminal is provided on the rear of the unit.

2.3 Frame Buffering and Latency
The LBH100A and LBH110A Series Media Converter 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. they are good packets. This eliminates
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. The "cut-through" technique permits collision fragment frames,
which are a result of late collisions, to be forwarded to add to the network traffic. Since
collisions and bad packets are more 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.
To minimize the possibility of dropping frames on congested ports, each
LBH100A and LBH110A Series Media Converter Switch dynamically allocates buffer
space from 128Kb memory pool, ensuring that heavily used ports receive very large buffer
space for packet storage. (Many other switches have their packet buffer storage space
divided evenly across all ports, resulting in a small, fixed number of packets to be stored
22

BLACK BOX®
Media Converter Switches
Installation and User Guide
per port. When the port buffer fills up, dropped packets result.) This dynamic buffer
allocation provides the capability for the maximum resources of the LBH100A and
LBH110A Series unit to be applied to all traffic loads, even when the traffic activity is
unbalanced across the ports. Since the traffic on an operating network is constantly varying
in packet density per port and in aggregate density, the LBH100A and LBH110A Series
Media Converter Switches are constantly adapting internally to provide maximum network
performance with the least dropped packets.
When the Converter 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 details.
Another feature implemented in LBH100A and LBH110A Series Media
Converter 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.

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). For fiber port 10BASE-FL or 100BASE-FX multi-mode, 50/125 or 62.5/125 microns
cabling can be used, whereas for single-mode, 9/125 microns cabling should be used. Fiber
cabling supports much longer cable distance and higher bandwidths as compared to copper
wiring.

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 P80-series switch ports are auto-sensing for either 10
and 100Mbps. Note that the auto-cross function does not operate, if the port is
fixed or not supporting auto-negotiation.
3.8.1 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.
3.8.2
Connecting Fiber Optic ST-type, “twist-lock”
The following procedure applies to installations using ST-type fiber connectors.
This procedure applies to ports using multi-mode ST fiber connectors.
1. Before connecting the fiber optic cable, remove the protective dust caps from the
tips of
the fiber connectors. Save these dust caps for future use.
2. Wipe clean the ends of the dual connectors with a soft cloth or lint-free lens tissue
dampened in alcohol. Make certain the connectors are clean before connecting.
Note:
One strand of the duplex fiber optic cable is coded using color bands
at regular intervals; you must use the color-coded strand on the associated
ports at each end of the fiber optic segment.
3. Connect the Transmit (TX) port (light colored post) on the Fiber port to the Receive
(RX) port of the remote device. Begin with the color-coded strand of the cable for
this first TX-to-RX connection.
4. Connect the Receive (RX) port (dark colored post) to the Transmit (TX) port of the
remote device. Use the non-color coded fiber strand for this.
5. The LINK LED on the front of the fiber connector will illuminate when a proper
connection has been established at both ends (and when power is ON in the unit). If

LINK is not lit after cable connection, the normal cause is improper cable polarity.
Swap the fiber cables at the fiber connector to remedy this situation.
Connecting Fiber Optic SC-type, "Snap-In"
The following procedure applies to installations using SC-type fiber connectors,
i.e., using multi-mode SC and SC single-mode. While connecting fiber media to
SC connectors, simply snap on the two square male connectors into the SC
female jacks of the Fiber connector until it clicks and secures.
3.8.3
3.8.4
Connecting Single-Mode Fiber Optic
When using single-mode fiber cable, be sure to use single-mode fiber port
connectors. Single-mode fiber cable has a smaller diameter than multi-mode
fiber cable (9/125 microns for single-mode, 50/125 or 62.5/125 microns for
multi-mode where xx/xx are the diameters of the core and the core plus the
cladding respectively). Single-mode fiber allows full bandwidth at longer
distances, about 20Km with the multi-mode SC.
The same procedures as for multi-mode fiber apply to single-mode fiber
connectors. Follow the steps listed in Section 3.8.2 above.

Power Budget Calculations for LBH100A and LBH110A Series,
Fiber Media
Receiver Sensitivity and Transmitter Power are the parameters necessary to
compute the power budget. To calculate the power budget of different fiber media
installations using products, the following equations should be used:
OPB (Optical Power Budget) = PT(min) - PR(min)
where PT = Transmitter Output Power, and PR = Receiver Sensitivity
Worst case OPB = OPB - 1dB(for LED aging) - 1dB(for insertion loss)
Worst case distance = {Worst case OPB, in dB} / [Cable Loss, in dB/Km]
where the “Cable Loss” for 62.5/125 and 50/125µm (m.m.) is 2.8 dB/km,
and the “Cable Loss” for 100/140 (Multi-mode) is 3.3 dB/km,
and the “Cable Loss” for 9/125 (Single-mode) is 0.5 dB/km
The following data has been collected from component manufacturer’s (HP’s, and
Siemens’) web sites and catalogs to provide guidance to network designers and installers

* Note: The use of either multi-mode or single-mode fiber to operate at 100Mbps speed
over long distances (i.e., over approx. 400 meters) can be achieved only if the following
factors are both applied:
•
•
The 100Mb fiber segment must operate in full-duplex (FDX) mode, and
The worst-case OPB of the fiber link must be greater than the fiber cable’s
passive Attenuation.
(Attenuation = Cable loss + LED aging loss + Insertion loss + safety factor)

Connections to NICs which support Auto-Negotiation, RJ-45 ports
The copper ports of LBH100-Series Media Converter 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 LBH100-Series, 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

4.0 OPERATION
Media Converter Switches
Installation and User Guide
4.1 Dual-Speed Functionality, and Switching
The LBH100A and LBH110A Series Media Converter Switches provide four
switched ports (three ports in the front and one on the rear). The architecture supports a
dual speed switching environment, with standard auto-negotiation capability.
The switched RJ-45 ports are full- or half-duplex auto-sensing for mode and
speed, and auto-cross for plug polarity. (See Section 2.2). When the connected device is 10
Mbps, the LBH100s obeys all the rules of 10 Mbps Ethernet configurations. The 10 Mbps
users can “communicate” with 100Mbps users as well as other 10 Mbps users through the
switch. Similarly, the 100Mbps traffic obeys the rules of 100Mbps Ethernet, and can
communicate with 10 Mb and 100Mb users.
LBH100A and LBH110A Series units are plug-and-play devices. There is no
software configuring to be done at installation or for maintenance. The only hardware
configuration settings is user options for port #2, to configure it FF/AN. The internal
functions of both are described below.

Installation and User Guide
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 LBH100A and
LBH110A Series Media Converter Switches operate in the store-and-forward switching
mode, which eliminates bad packets and enables peak performance to be achieved when
there is heavy traffic on the network.

BLACK BOX®
Media Converter Switches
Installation and User Guide
Switching, Address Learning
The LBH100A and LBH110A 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 removed or moved from one segment to another, the LBH100- and
LBH110- Series switch 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 independently support auto-cross (MDI or MDIX) in auto-
negotiation mode. No cross-over cable is needed. The ports do the auto-cross selection only
during auto-negotiation, and it will not take effect if the port is in fixed mode (port #2 can
be fixed to FDX on some models). Operation is according to the IEEE 802.3u standard.
When an RJ-45 cable connection is made, and each time a LINK is enabled, auto-
negotiation takes place. The LBH100A and LBH110A Series 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 and both sides will agree to the speed and mode being
used. Depending upon the device connected, this will result in agreement to operate at
either 10 Mbps or 100Mbps speed, full- or half-duplex mode.
4.3 (F- H) Switch, Full-Duplex or Half-Duplex options for Fiber port # 1
The (F–H) manual switch has been provided for fiber port #1, for fixing that port
at Full or Half Duplex as per the requirements. The (F-H) manual switch is being located
underneath the fiber port. The Fiber port with 10Mb is being set at Half-Duplex, and the
100Mb being set at Full-Duplex as default from the factory. The port can be set at the
required mode, by sliding the manual switch position to “F” or “H”.
