• Key Features in the Device
QoS:
The switch offers powerful QoS function. This function supports 802.1p
VLAN tag priority and DSCP on Layer 3 of network framework.
VLAN:
Supports Port-based VLAN, IEEE802.1Q Tag VLAN. And supports 24 active
VLANs and VLAN ID 1~4094.
Port Trunking:
Allows one or more links to be aggregated together to form a Link
Aggregation Group by the static setting.
IGMP Snooping:
Support IGMP version 2 (RFC 2236): The function IGMP snooping is used
to establish the multicast groups to forward the multicast packet to the
member ports, and, in nature, avoid wasting the bandwidth while IP
multicast packets are running over the network.
Q-in-Q VLAN for performance & security:
Limiting the broadcast traffic to within the same VLAN broadcast domain
also enhances performance. Q-in-Q, the use of double VLAN tags is an
efficient method for enabling Subscriber Aggregation. This is very useful in
the MAN.
SNMP:
SNMP agent In the device, SNMP agent is a client software which is
operating over SNMP protocol used to receive the command from SNMP
manager (server site) and echo the corresponded data, i.e. MIB object.
Besides, SNMP agent will actively issue TRAP information when happened.
Power Saving:
The Power saving using the "ActiPHY Power Management" and
"PerfectReach Power Management" two techniques to detect the client idle
and cable length automatically and provides the different power. It could
efficient to save the switch power and reduce the power consumption.
PoE:
24-PoE ports allow power to be supplied to end devices, such as Wireless
Access Points or VoIP Phones, directly through the existing LAN cables,
eliminating costs for additional AC wiring and reducing Installation Cost. It
was compliant with IEEE802.3af standard. It provides the endpoint with
48VDC power through RJ-45 pin 1, 2, 3, 6. SM24P-POEprovides 185 watts

• TP Port and Cable Installation
⇒In the switch, TP port supports MDI/MDI-X auto-crossover, so both types of
cable, straight-through (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 1, 2, 3, 6 in
10/100M TP; 1, 2, 3, 4, 5, 6, 7, 8 to 1, 2, 3, 4, 5, 6, 7, 8 in Gigabit TP) and
crossed-over (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 3, 6, 1, 2) can be used.
It means you do not have to tell from them, just plug it.
⇒Use Cat. 5 grade RJ-45 TP cable to connect to a TP port of the switch and the
other end is connected to a network-aware device such as a workstation or a
server.
⇒Repeat the above steps, as needed, for each RJ-45 port to be connected to a
Gigabit 10/100/1000 TP device.
Now, you can start having the switch in operation.
• Power On
The switch supports 100-240 VAC, 50-60 Hz power supply. The power
supply will automatically convert the local AC power source to DC power. It does not
matter whether any connection plugged into the switch or not when power on, even
modules as well. After the power is on, all LED indicators will light up and then all off
except the power LED still keeps on. This represents a reset of the system.
• Firmware Loading
After resetting, the bootloader will load the firmware into the memory. It will
take about 30 seconds, after that, the switch will flash all the LED once and
automatically performs self-test and is in ready state.
2-1-2. Cabling Requirements
To help ensure a successful installation and keep the network performance
good, please take a care on the cabling requirement. Cables with worse
specification will render the LAN to work poorly.

2-1-2-1. Cabling Requirements for TP Ports
For Fast Ethernet TP network connection
⎯The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of
100 meters.
Gigabit Ethernet TP network connection
⎯The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of
100 meters. Cat. 5e is recommended.
2-1-2-3. Switch Cascading in Topology
• Takes the Delay Time into Account
Theoretically, the switch partitions the collision domain for each port in switch
cascading that you may up-link the switches unlimitedly. In practice, the network
extension (cascading levels & overall diameter) must follow the constraint of the
IEEE 802.3/802.3u/802.3z and other 802.1 series protocol specifications, in which
the limitations are the timing requirement from physical signals defined by 802.3
series specification of Media Access Control (MAC) and PHY, and timer from some
OSI layer 2 protocols such as 802.1d, 802.1q, LACP and so on.
The fiber, TP cables and devices’ bit-time delay (round trip) are as follows:
1000Base-X TP, Fiber 100Base-TX TP 100Base-FX Fiber
Round trip Delay: 4096 Round trip Delay: 512
Cat. 5 TP Wire: 11.12/m Cat. 5 TP Wire: 1.12/m Fiber Cable: 1.0/m
Fiber Cable : 10.10/m TP to fiber Converter: 56
Bit Time unit : 1ns (1sec./1000 Mega bit) Bit Time unit: 0.01µs (1sec./100 Mega bit)
Table 2-2
Sum up all elements’ bit-time delay and the overall bit-time delay of
wires/devices must be within Round Trip Delay (bit times) in a half-duplex network
segment (collision domain). For full-duplex operation, this will not be applied. You
may use the TP-Fiber module to extend the TP node distance over fiber optic and
provide the long haul connection.
• Typical Network Topology in Deployment
A hierarchical network with minimum levels of switch may reduce the timing
delay between server and client station. Basically, with this approach, it will
minimize the number of switches in any one path; will lower the possibility of
network loop and will improve network efficiency. If more than two switches are
connected in the same network, select one switch as Level 1 switch and connect all
other switches to it at Level 2. Server/Host is recommended to connect to the Level
1 switch. This is general if no VLAN or other special requirements are applied.

Case1: All switch ports are in the same local area network. Every port can access
each other (See Fig. 2-2).
Fig. 2-2 No VLAN Configuration Diagram
If VLAN is enabled and configured, each node in the network that can
communicate each other directly is bounded in the same VLAN area.
Here VLAN area is defined by what VLAN you are using. The switch
supports both port-based VLAN and tag-based VLAN. They are different in practical
deployment, especially in physical location. The following diagram shows how it
works and what the difference they are.
Case2a: Port-based VLAN (See Fig.2-3).
Fig. 2-3 Port-based VLAN Diagram
1. The same VLAN members could not be in different switches.
2. Every VLAN members could not access VLAN members each other.
3. The switch manager has to assign different names for each VLAN groups
at one switch.
