(Quality of Service), Spanning Tree, VLAN, Port Trunking, Bandwidth ontrol, Port
Security, SNMP/RMON, IGMP Snooping capability via the intelligent software. It is
suitable for both metro-LAN and office application.
In this switch, Port 45 to Port 48 include two types of media --- TP and SFP
Fiber (L , BiDi L ...); this port supports 10/100/1000Mbps TP or 1000Mbps SFP
Fiber with auto-detected function. 1000Mbps SFP Fiber transceiver is used for high-
speed connection expansion.

10/100/1000Mbps TP is a standard Ethernet port that meets all IEEE
802.3/u/x/z Gigabit, Fast Ethernet specifications. 1000Mbps SFP Fiber transceiver
is a Gigabit Ethernet port that fully complies with all IEEE 802.3z and 1000Base-
SX/LX standards.
1000Mbps Single Fiber WDM (BiDi) transceiver is designed with an optic
Wavelength Division Multiplexing (WDM) technology that transports bi-directional
full duplex signal over a single fiber simultaneously.
For upgrading firmware, please refer to the Section 3-22 for more details.
The switch will not stop operating while upgrading firmware and after that, the
configuration keeps unchanged.

information when happened.
RMON is the abbreviation of Remote Network Monitoring and is a branch of
the SNMP MIB.
The device supports MIB-2 (RF 1213), Bridge MIB (RF 1493), RMON
MIB (RF 1757)-statistics Group 1,2,3,9, Ethernet-like MIB (RF 1643),
Ethernet MIB (RF 1643) and so on.
IGMP Snooping:
Support IGMP version 2 (RF 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.

The optional SFP modules are hot swappable, so you can plug or unplug it
before or after powering on.
1. Verify that the SFP module is the right model and conforms to the chassis
2. Slide the module along the slot. Also be sure that the module is properly
seated against the slot socket/connector
3. Install the media cable for network connection
4. Repeat the above steps, as needed, for each module to be installed into
slot(s)

T TP Port and Cable Installation T
⇒ In the switch, TP port supports MDI/MDI-X auto-crossover, so both types of
cable, straight-through ( able 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 ( able 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 at. 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.
• T Power On T
The switch supports 100-240 VA , 50-60 Hz power supply. The power
supply will automatically convert the local A power source to D 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 immediately
and then all off except the power LED still keeps on. This represents a reset of the
system.
• Firm
T ware Loading T
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. Installing Chassis to a 19-Inch Wiring Closet Rail
Caution: Allow a proper spacing and proper air ventilation for the cooling fan
at both sides of the chassis.
⇒ Wear a grounding device for electrostatic discharge.
⇒ Screw the mounting accessory to the front side of the switch (See Fig. 2-2).
⇒ Place the hassis into the 19-inch wiring closet rail and locate it at the proper
position. Then, fix the hassis by screwing it.
2-1-3. Cabling Requirements
To help ensure a successful installation and keep the network performance
good, please take a care on the cabling requirement. ables with worse
specification will render the LAN to work poorly.

2-1-3-1. Cabling Requirements for TP Ports
⇒ For Fast Ethernet TP network connection
 The grade of the cable must be at. 5 or at. 5e with a maximum length of
100 meters.
⇒ Gigabit Ethernet TP network connection
 The grade of the cable must be at. 5 or at. 5e with a maximum length of
100 meters. at. 5e is recommended.
2-1-3-2. Cabling Requirements for 1000SX/LX SFP Module
It is more complex and comprehensive contrast to TP cabling in the fiber
media. Basically, there are two categories of fiber, multi mode (MM) and single
mode (SM). The later is categorized into several classes by the distance it supports.
They are SX, LX, LHX, XD, and ZX. From the viewpoint of connector type, there
mainly are L and BIDI L .
 Gigabit Fiber with multi-mode L SFP module
 Gigabit Fiber with single-mode L SFP module
 Gigabit Fiber with BiDi L 1310nm SFP module
 Gigabit Fiber with BiDi L 1550nm SFP module
The following table lists the types of fiber that we support and those else not
listed here are available upon request.

2-1-3-3. 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 ontrol (MA ) and PHY, and timer from some
OSI layer 2 protocols such as 802.1d, 802.1q, LA P 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
at. 5 TP Wire:
11.12/m at. 5 TP Wire:
1.12/m
Fiber able: 1.0/m
Fiber able : 10.10/m TP to fiber onverter: 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.

ase1: All switch ports are in the same local area network. Every port can access
each other (See Fig. 2-3).
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.
