Caution!
To reduce risk of electrical shock and fire and to maintain proper operation,
ensure that the safety requirements stated hereunder are met!
Before installing the MS 104/5, ensure the following:
1. All power to the MS 104/5 is cut off.
2. By visual inspection, no part is damaged.
Do not connect or disconnect the electrical cable and/or power cord during
lightning strikes or thunderstorms.

MS 104/5 ML46758, Rev. 01 June 2002
Overview
General
MS 104/5 are members of a families of mixed media Ethernet switches.
Models
The models in each family are described in Appendix A: Models.
Applications
Figure 1: Applications of the MS 104 and MS 105
Features
Available
• Domain-per-Port – Partitioning of networks connected to ports into
separate collision domains.
• Store-&-Forward – Performance of packet CRC and legal size check
prior to resolving whether it is a runt, jabber, or CRC error packet and
discarding it if it is so.
• Auto-Negotation (or Auto-Sensing) – Automatic self reconfiguration
capability of the 10BASE-T/100BASE-TX switching ports to operate
optimally, i.e., at 100 Mbps speed (rather than at 10 Mbps) and in
full-duplex mode (rather than in half-duplex mode) if the co-port1too has
auto-negotation capability. Auto-negotation can be activated or de-
activated for each port individually.
• Wire-Speed Operation – Transmission and reception of packets by all
ports at full link speed with zero packet loss.
1Co-port is another port which receives from or forwards to an MS 104/5 port.
6

MS 104/5 ML46758, Rev. 01 June 2002
• Auto-Configuration – Each 10/100Base-TX port can be connected to an
Ethernet MDI or MDI-X port with a straight or cross-over cable since the
port automatically configures itself to suit the cable type and co-port
interface.
• Filtering/Forwarding Database (FDB) – Current map of connected
stations (identified by their MAC address) to ports. The map is dynamically
updated and can maintain as many as 1024 MAC addresses.
• Auto-Learning – Automatic addition of MAC addresses of new stations to
FDB.
• Auto-Aging – Clearance of MAC address of station in MS 104/5 FDB if
not accessed for 5 minutes.
• VLAN Support – Switching of packets of length up to 1536 bytes.
• Broadcast Storms Prevention – Prevention of broadcast storms
resulting from streaming or over-jabbering stations.
• Fiberoptic Cabling – Connectivity of single-fiber singlemode cables and
dual fiber singlemode or multimode cables.
• VBC – Virtual Broadcasting Restriction. Port P1 can send and receive
broadcast and unicast packets to/from the other ports (P2, P3, etc.).
However, the other ports (P2, P3, etc.) cannot send and receive broadcast
packets to each other; they can only send and receive unicast packets to
each other.
Optional
• Packet Prioritization – Assignment of high or low processing priority to a
packet on the basis of Port, VLAN, or ToS.
• Flow Control – Forcing of the transmitting station to temporarily back off
when the global memory of the MS 104/5 becomes saturated. This feature
prevents packet loss. It is applicable to ports that operate in full-duplex
mode. It can be activated for each port individually.
• Backpressure – Forcing of transmitting station to temporarily back off
when the global memory of the MS 104/5 becomes saturated. This feature
prevents packet loss. It is applicable to ports that operate in half-duplex
mode. It can be activated for each port individually.
• No Aging – Prevention of clearance of MAC addresses of stations in
MS 104/5 FDB.
• VBC – Virtual Broadcasting Restriction. Each port can be enabled or
disabled to send/receive broadcast packets from each of the other ports
individually. However, unicast packets can be sent between any two ports.
• Port Isolation – Each port can be isolated2from or grouped3with each of
the other ports individually.
For example, port P1 can be grouped with all the other ports while the
other ports are isolated from each other.
2disabled to send/receive broadcast and unicast packets.
3enabled to send/receive broadcast and unicast packets.

MS 104/5 ML46758, Rev. 01 June 2002
As another example, ports P1 and P3 can be put in one group, ports P2
and P4 in another.

Ports
Power Port
3-prong receptacle for 110V/60Hz or 220V/50Hz line (mains) power input.
100Base-FX Ports
One or two 100Base-FX ports. Each port operates at 100 Mbps, is fitted with a
fiberoptic SC or MT-RJ connector, transmits and receives on 1310 nm or 1550
nm carrier wavelength, and can be connected with a single-fiber singlemode
cable or dual-fiber singlemode cable or dual-fiber multimode cable. The power
budget available depends on the model as described in Appendix A: Models.
10/100Base-TX Ports
Two or four 10/100Base-TX ports. Each port has full auto-negotiation capability,
is fitted with an RJ45 UTP connector, and can be connected with a Category 5
cable up to 100 meters long. To use longer cables, consult your representative.
DIP Switch
12-toggle DIP switch for configuring the operation mode of 10/100Base-TX ports
individually. The toggles are divided into three groups marked AUTO, 10/100,
and FD/HD. AUTO designates auto-negotiation, 10/100 designates 10/100 Mbps
data rate, FD/HD designates full-duplex/half-duplex. Each toggle marked with a
number (e.g., 2, 3, 4or 5) is functional. The number designates the associated
port. Unmarked toggles are not functional and so their position may be ignored.
Table 1 specifies each DIP switch toggle, its two positions, and the function of
each position.
Note
To enable a 10/100 or FD/HD toggle to function, the AUTO toggle marked
with the same number must be set to the DOWN position, i.e.,
auto-negotiation must be disabled!

Installation and Setup
Package Contents
• MS 104/5
• Power Cord
• CD containing User Manual
Procedure
Install the MS 104/5 as follows:
1. Place the MS 104/5 on a flat stable surface (e.g., desk top).
2. Connect the MS 104/5 fiberoptic data ports TX and RX to the device(s),
ensuring that for each fiber, one end is connected to an RX port while the
other end is connected to a TX port as shown in Figure 5.
3. Interconnect the MS 104/5 electrical data ports and other devices.
Figure 5: Interconnection of MS 104/5 and another Device
4. With the aid of Table 1, set the DIP switch (on the front panel).
Note
If the device port (to which the MS 104/5 electrical data port is
connected) does not have auto-negotiation capability, the MS 104/5
port operates in half-duplex mode and at the same speed of the device port.
5. Connect one end of the power cord to the MS 104/5 power port.
6. Connect the other end of the power cord to the ac line power (mains) to
power on the MS 104/5.
Note
If the DIP switch setting is changed while the MS 104/5 is powered on,
disconnect then reconnect the power cord to enable the MS 104/5 to
operate according to the new setting.
Operation
The MS 104/5 becomes fully operational within a few seconds after being
powered on.
Its operation can be monitored by interpreting the status of its LEDs with the aid
of Table 2. If there is a problem, use the chapter Troubleshooting to resolve it.

MS 104/5 ML46758, Rev. 01 June 2002
Troubleshooting
The troubleshooting procedure is given in Table 3. Read the entries in the
column Problem until you reach the problem that applies to the MS 104/5. Then
perform the corrective action(s) appearing in the same row. If the problem
persists, note the status of all the LEDs and consult your MRV representative.

Appendix B: Cleaning Optical
Connectors
General
Intrusions (e.g., dust, grease, etc.) at the interface of two optical fibers, such as
at a pair of coupled connectors, attenuate the signal through the fiber.
Consequently, optical connectors must be cleaned before they are coupled with
other connectors.
Tools and Equipment
Following are tools and equipment required for cleaning connectors.
• Dust caps
Caps for protecting the connector from intrusions. A cap is usually made
from flexible plastic. When placing a cap over a connector, avoid pressing
it against the fiber ferula surface in the connector so as to prevent
contamination.
• Isopropyl alcohol
Solvent for contaminants.
• Tissues
Soft multi-layered fabric made from non-recycled cellulose.
Procedure
The procedure for cleaning connectors is as follows:
1. If no stains are present, using a new clean dry tissue, gently rub, in small
circular motions, the exposed fiber surface and surrounding area in the
connector to remove dust.
2. If stains are present,
A. Moisten a new clean dry tissue with isopropyl alcohol and gently
rub, in small circular motions, the exposed fiber surface and
surrounding area in the connector to remove the stains.
B. Using a new clean dry tissue, gently rub, in small circular motions,
the exposed fiber surface and surrounding area in the connector to
remove the dissolved stains and excess isopropyl alcohol.
C. If a connector is not to be coupled with another immediately, cover
it with a dust cap.
