Hardware Description
This Section mainly describes the hardware of the MIL-S4800 Switch and gives a
physical and functional overview on the certain switch.
Physical Dimension
The MIL-S4800 Switch’s physical dimension is 440mm x 225mm x 44mm (W x D
x H).

Front Panel
The Front Panel of the MIL-S4800 Switch consists of 48x 10/100Base-TX RJ-45
ports (Auto MDI/MDIX), 1 10/100/1000T port and 1 SFP port. The LED Indicators
are also located on the front panel of the Switch.
RJ-45 Ports (Auto MDI/MDIX): 48x 10/100 N-way auto-sensing for
10Base-T or 100Base-TX connections.
In general, MDI means connecting to another Hub or Switch while MDIX
means connecting to a workstation or PC. Therefore, Auto MDI/MDIX would
allow connecting to another switch or workstation without changing
non-crossover or crossover cabling.
Giga port: 1 10/1000/100T UTP port and 1 SFP port.

Rear Panel
The 3-pronged power plug is located at the rear Panel of the MIL-S4800 Switch
as shown in Figure. The Switch will work with AC in the range of 100-240V and
Frequency of 50-60Hz/0.26A. The power plug includes a fuse that it can be
replaced when fuse is burned. If the power plug has problem on the powering,
please check the fuse first for sure.

Desktop Installation
Set the switch on a sufficiently large flat space with a power outlet nearby. The
surface where for putting switch should be clean, smooth, level and sturdy. Make
sure there is enough clearance around the switch to allow attachment of cables,
power cord and allow air circulation.
Attaching Rubber Pads
1.
Make sure mounting surface on the bottom of the switch is grease and dust
free.
2.
Remove adhesive backing from the Rubber Pads.
3.
Apply the Rubber Pads to each corner on the bottom of the switch. These
footpads can prevent the switch from shock/vibration.
Rack-mounted Installation
The MIL-S4800 Switch comes with a rack-mount kit and can be mounted in an
EIA standard size, 19-inch Rack. The Switch can be placed in a wiring closet with
other equipment. Perform the following steps to rack mount the switch:
1.
Position one bracket to align with the holes on one side of the switch and
secure it with the smaller bracket screws. Then attach the remaining bracket
to the other side of the switch.
2.
After attached mounting brackets, position the MIL-S4800 switch in the rack
by lining up the holes in the brackets with the appropriate holes on the rack.
Secure the switch to the rack with a screwdriver and the rack-mounting
screws.
[Note] For proper ventilation, allow about at least 4 inches (10 cm) of clearance
on the front and 3.4 inches (8 cm) on the back of the Switch. This is especially
important for enclosed rack installation.
5
Power On
Connect the power cord to the power socket on the rear panel of the Switch. The
other side of power cord connects to the power outlet. The internal power supply
of the switch works with AC voltage range of 100-240V and Frequency
50~60Hz./0.26A Check the power indicator on the front panel to see if power is
properly supplied.
Troubleshooting
This section is intended to help you solve the most common problems on the
MIL-S4800 Switch.
Incorrect connections
The switch port can auto detect straight or crossover cable when you link switch
with other Ethernet device. For the RJ-45 connector should use correct UTP or
STP cable, 10/100Mbps port use 2 pairs twisted cable and Gigabit 1000T port use
4 pairs twisted cable. If the RJ-45 connector is not correct pin on right position
then the link will fail.
For fiber connection, please notice that fiber cable mode
and fiber module should be match.
Faulty or loose cables
Look for loose or obviously faulty connections. If they appear to be OK, make sure
the connections are snug. If that does not correct the problem, try a different
cable.
6
Non-Standard cables
Non-Standard and miss-wired cables may cause numerous network collisions
and other network problem, and can seriously impair network performance. A
category 5-cable tester is a recommended tool for every 100Base-T network
installation.
RJ-45 ports: use unshielded twisted-pair (UTP) or shield twisted-pair ( STP )
cable for RJ-45 connections: 100
connections or 100
Category 3, 4 or 5 cable for 10Mbps
Category 5 cable for 100Mbps connections. Also be sure
that the length of any twisted-pair connection does not exceed 100 meters (328
feet). Gigabit port should use Cat-5 or cat-5e cable for 1000Mbps connections.
The length does not exceed 100 meters.
Improper Network Topologies
It is important to make sure have a valid network topology. Common topology
faults include excessive cable length and too many repeaters (hubs) between end
nodes. In addition, you should make sure that your network topology contains no
data path loops. Between any two ends nodes, there should be only one active
cabling path at any time. Data path loops will cause broadcast storms that will
severely impact your network performance.
Diagnosing LED Indicators
The switch can be easily monitored through panel indicators to assist in
identifying problems, which describes common problems user may encounter and
where you can find possible solutions.
If the power indicator does turn on when the power cord is plugged in, you may
7
have a problem with power outlet, or power cord. However, if the switch powers
off after running for a while check for loose power connections, power losses or
surges at power outlet. If the problem still cannot be resolved, please contact the
local dealer for assistance.
