(UTP) or shielded twisted pair (STP) cabling systems compliant
with the IEEE 802.3u 100Base TX standard for Category 5. The
cable between the switch and the link partner device (router , hub,
workstation, etc.) must be less than 100 metres long.
2. The 100 Fx fibre link on the optional multi-mode module must use
either 50 or 62.5/125 micron multi-mode fibre cable. You can link
two devices over a distance of up to 2 Km. ST or SC connector
types are supported.
3. The 100 Fx fibre link on the optional single mode module must
use 8/125 or 9/125-micron single-mode fibre cable. You can link
two devices over a distance of up to 30 Km in full duplex mode or
412 m (1,352 ft.) in half-duplex. The single mode module uses
the SC type connector.
4. The dual Gigabit fibre Sx or Lx complies with IEEE802.3z. The
SC type connector is used.
Sx: Module must use either 50 or 62.5/125 micron multimode
fibre cable. Supports distances up to 500 metres.
Lx: Module must use either 8/125 or 9/125-micron single mode
fibre cable. Supports distances up to 10 Km.
5. The console port is an RS232 port and should not be used for
cable distances greater than 20 m.

Desktop Installation
1. Locate the switch in a clean, flat and safe position that has easy
access to AC power. Ensure that there is sufficient clearance
around the switch to enable air circulation.
2. Fit the self-adhesive rubber feet to the underside of the switch.
Installing The Switch Into a 19” Rack
1. Identify the required locations and ensure that there is at least
10cm clearance at the front and rear of the switch to allow cables
to be accommodated.
2. Fit the supplied rack mount bracket on both side plates of the
switch using a screwdriver.
3. Locate the switch into the rack and align the holes in the brackets
with holes in the rack vertical strips. Secure the switch using the

24 and 16 Port Smart Switch II – User Manual Page7
Completing the Installation
When the switch has been installed as specified above, then the unit
can be configured as detailed below: -
1. Apply AC power to the switch. The green Power LED on the front
panel should light.
2. Connect the Cat. 5/5e twisted pair cables from the network
partner devices to the RJ-45 ports on the front panel of the switch.
When a connection is obtained, the green LK/ACT LED
associated with the port will light.
3. If the fibre uplink is used, then connect the fibre link to the partner
device (media converter , fibre NIC card or fibre switch etc). V erify
that the green Link LED on the fibre module is lit which indicates
that the optical link is valid.
4. If advanced modes such as port-based VLANs are needed, then
use the console port to configure the switch.
5. If legacy devices that do not support auto-negotiation are
connected to the RJ45 ports then it may be necessary to
configure the switch to match the speed and duplex modes of the
partner devices.
6. Note that auto-negotiation can take up to 30 seconds to complete
depending on the partner device.

Optical Link Wavelength
The 100 Fx optional modules operate at the 1310nm optical
wavelength. The Gigabit Lx Singlemode module operates at
1310nm and the Gigabit Sx multimode module operates at 850nm
optical wavelength.
Optical Link Calculations
The maximum distance between any two fibre optic devices is
determined by a number of factors including optical link loss, the
type and number of patch cords and joints in the link, the launch
power of the transmitter and the sensitivity of the receiver. These
variables make calculating the maximum working distance between
two units quite difficult and so it is best to design networks using
optical loss budgets rather than using just working distance.
Dual Gigabit 1000BaseT copper module
The RJ-45 will auto-negotiate 100Base-TX and Gigabit 1000T
connections. Support for Auto MDI/MDIx is also provided.
It should be noted that Gigabit 1000T (1000Mbps) connection must
use Cat-6 or Cat5-E twisted cable pair cable. If use cat-5 cable is
used then support 100Mbps link speed is available only. The
available link distance is up to 100Meters.

priority than the traffic arriving at ports that have not been assigned
high priority.
The Priority Weighted Ration (High: Low) field is used to set the
precedence ratio between the high and low prioritised traffic.
There are 4 different ratios that can be allocated: -
1:0 -This will force the switch to process all high-prioritised traffic
before it starts to process traffic that has been prioritised as low.
4:1 -This will force the switch to give high priority traffic 4 times more
precedence to that of low priority packets. For every low priority
packet that is processed 4 high priority packets will be processed.
8:1 - This will force the switch to give high priority traffic 8 times
more precedence to that of low priority packets.
16:1 - This will force the switch to give high priority traffic 16 times
more precedence to that of low priority packets.
