GETTING STARTED CHAPTER 2: GETTING STARTED
2.1.3 Wiring and Grounding Guidelines
The Multinet4 requires several different types of connectors, cables, and wires.
Requirements and recommendations are listed below:
Fiber The fiber cables connected to the Multinet4 must be:
• non-dispersion shifted, single mode (SM)
or
• multi-mode (MM) fiber cables defined by the Telcordia Technologies
General Recommendation 20-CORE standard
and
• terminated with LC, ST, and SC connectors
Grounding The primary ground stud located on the rear of the chassis must be used to
connect to an approved ground with a wire meeting the following criteria:
• 14 AWG (minimum)
• a maximum of five feet in length
• terminated on the ground lug side with a #10 ring lug
Facility Power The facility power cabling attached to the Multinet4 chassis must meet the
Copper Copper I/O cables and connectors must be shielded.
It is mandatory that an accessible disconnect is provided in the Installation wiring
2.1.4 Fiber Optic Safety
Before installing the Multinet4 you should be aware that devices that employ laser
technology, such as the fiber optical LC ports and associated cabling, can be dangerous.
Do not look directly into a fiber optic port or into the end of a fiber optic line. Doing so
could cause injury to your eye or blindness. Always assume that there is laser activity in the
line or port, even if the device is powered down. As a reminder, whenever this manual calls
for the handling of fiber optic lines, those instructions will be accompanied by a “Laser
Warning,” as follows:
following criteria:
• cabling constructed using 14 AWG stranded wire
• cable firmly attached to the terminal holes of the non-polarized
power unit, as illustrated in FIGURE 2–11:: Non-Polarized Power Input.
• cable routed and strain relieved to the chassis according to good
wiring practices
DO NOT LOOK INTO A FIBER OPTIC CABLE OR PORT! These can produce invisible light that
may do serious eye damage. Always assume that fiber optic cables or ports are actively
radiating light energy.
2–2 MULTINET4 MULTI-PORT SERIAL SERVER & MANAGED SWITCH – INSTRUCTION MANUAL
Page 27
CHAPTER 2: GETTING STARTED GETTING STARTED
2.1.5 Fiber Optic Handling
Contamination from dust, dirt, oils from the hands and other sources can impede the
transmission and reception of optical signals through the optical fibers.When handling the
optical connectors and fiber cables, follow these precautions to minimize the
contamination of the connectors and ports:
• Cover optical connectors and ports with dust caps when they are not in use.
• Do not touch fiber tips or the interior of optical ports when handling fiber cables
and connectors.
• Clean fiber optic connectors as described in 2.4.2.1: Cleaning Connectors, prior to
making any optical connection.
• Clean optical ports as described in 2.4.2.2: Cleaning Optical Ports if contaminants
or degraded performance are noted on the interface.
Fiber optic connectors should be cleaned after each use and optical ports should be
cleaned if you notice contamination or degraded performance.
Fiber optic cables and connectors are fragile and can be easily broken through rough
handling. When handling fiber optic media, take the following precautions:
• Do not strike the fiber cable with tools.
• Do not pinch, crimp, or compress the jacketing of the optical cable.
• Do not use less than the minimum bend radius of 3 inches (7.62 cm) when routing
or coiling cables.
2.1.6 External Connections
You can speed up the installation of the Multinet4 by having the following equipment and
information on hand before beginning:
• A supply of cables and connectors of the required types.
• IP addresses for new devices and any existing devices you will be connecting to.
• Your notes on naming conventions and end point information.

2.3.1 Mounting
Before mounting, please note the following:
1. Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the
operating ambient temperature of the rack environment may be greater than room
ambient. Therefore, consideration should be given to installing the equipment in an
environment compatible with the maximum ambient temperature (Tma) specified by
the manufacturer.
2. Reduced Air Flow - Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation of the equipment is not compromised.
3. Mechanical Loading - Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
4. Circuit Overloading - Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits might
have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
5. Reliable Earthing - Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other than
direct connections to the branch circuit (e.g. use of power strips)."

console port (the RS232 port) to the PC.
2.3.3.2 Alarm Port
Resevered for future use.
2.3.4 Connecting Network Cables
There are three types of connections that can be made to the Multinet4. They are serial,
Ethernet copper, and Ethernet fiber optic. The following sections describe each type of
connection separately.
2.3.4.1 Connecting Serial Cables
This procedure assumes that one end of the Serial device cable is already attached to the
end unit. Be aware of the serial port numbering scheme when installing the cables see (see
section1.3: Pinouts). The ports are configured in software later on and if a device is
accidentally connected to the wrong port it will be difficult to detect.
Connect cables to the serial ports as described below (A 3/32” slotted screwdriver is
required.):
1. Remove the plug portion of the phoenix connector by loosening the two captive
mounting screws.
2. Strip back 1/4" off the insulation of the wires.
3. Loosen saddle screws and insert each conductor firmly into a terminal hole of the

GETTING STARTED CHAPTER 2: GETTING STARTED
5. Tighten the saddle screws until the wires are secure.
6. Re-insert the plug into the phoenix connector and secure the two captive mounting
screws.
Note
Serial cables must be shielded. It is recommended that high quality Belden 9843 cables be
used whenever possible to provide reliable serial communication.
2.3.4.2 Connecting RJ45 Twisted Pair
The RJ45 ports of the Multinet4 can be connected to the following two media types:
100Base-TX and 10Base-T. CAT Five 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 m (328 ft.).
Note
It is recommended that high quality CAT. 5 cables (which work with 10 Mb and 100 Mb) be
used whenever possible to provide flexibility in a mixed-speed network, as dual-speed
ports are auto-sensing for 10 and 100 Mb/s.
The following procedure describes how to connect a 10Base-T or 100Base-TX twisted pair
segment to the RJ45 port. The procedure is the same for both unshielded and shielded
twisted pair cables.
Z Using standard twisted pair media, insert either end of the cable
with an RJ45 plug into the RJ45 connector of the port.
Even though the connector is shielded, either unshielded or
shielded cables may be used.
Z Connect the other end of the cable to the corresponding device.
Z Use the LINK LED to ensure connectivity by noting that the LED will
be illuminated when the unit is powered and connection is
established.
2.3.4.3 Connecting ST-type Fiber Optics (twist-lock)
The following procedure applies to installations using modules with ST-type fiber
connectors.
Z Before connecting the fiber optic cable, remove the protective dust
caps from the tips of the connectors on the module.
Save these dust caps for future use.
Z Wipe clean the ends of the dual connectors with a soft cloth or
lintfree lens tissue dampened in alcohol.
Ensure the connectors are clean before proceeding.
Note
One strand of the duplex fiber optic cable is coded using color bands at regular intervals.
The color-coded strand must be used on the associated ports at each end of the fiber optic
segment.
Z Connect the transmit (TX) port on the module (light colored post) to
the receive (RX) port of the remote device.
Begin with the color-coded strand of the cable for this first TX-toRX connection.
2–14 MULTINET4 MULTI-PORT SERIAL SERVER & MANAGED SWITCH – INSTRUCTION MANUAL
Page 39
CHAPTER 2: GETTING STARTED GETTING STARTED
Z Connect the receive (RX) port on the module (dark colored post) to
the transmit (TX) port of the remote device.
Use the non-color coded fiber strand.
The LINK LED on the module will illuminate when a connection has been established at
both ends (assuming power is ON). If LINK is not lit after cable connection, the cause may
be improper cable polarity. Swap the fiber cables at the module connector to remedy this
situation.
2.3.4.4 Connecting SC-type or LC-type Fiber Optics (snap-in)
The following procedure applies to installations using modules with SC-type or LC-type
connectors.
When connecting fiber media to SC/LC connectors, simply snap the two square male
connectors into the module’s SC/LC female jacks until the click and secure.
2.3.4.5 Connecting Single-mode Fiber Optics
When using single-mode fiber cable, be sure to use single-mode fiber port connectors.
Single-mode figer cable has a smaller diameter than multi-mode fiber cable (9/125
microns for single-mode versus 50/150 or 62.5/125 microns for multi-mode, where xx/yy
represent the core diameters and the core plus cladding respectively). Single-mode fiber
allows full bandwidth at longer distances and may be used to connect 10 Mb nodes up to
10 Km.
The same connection procedures for multi-mode fiber apply to single-mode fiber
connectors. Follow the steps listed in 2.3.4.3: Connecting ST-type Fiber Optics (twist-lock)
and 2.3.4.4: Connecting SC-type or LC-type Fiber Optics (snap-in) shown above.

4.2.4.3 Time: Persistence
This screen enables you to set the time and date persistence feature (similar to the “Save
Time Interval” feature offered by other manufacturers). This is used to support systems
that do not have a clock with battery backup. When the power to these systems is cycled,
the clock may come up in an undefined state. With persistence enabled the clock is set to
the last known good time and date. This time and date clearly will not be correct but is
likely to be close enough to the actual time and date that the system will be able to
continue operating without difficulty.
This feature is useful in an environment where a Multinet4 keeps its time and date current
via an NTP server that it accesses through a VPN tunnel that uses certificates for
authentication. If the power to the Multinet4 is cycled and the time and date were to come
up in an undefined state, it is likely that the VPN authentication would fail because the
system's time and date would not match the valid dates on the VPN peer certificate. The
system would then not be able to access the NTP server and would be permanently cut off
