1. Introduction

24+2G switch is a high performance web-managed SNMP Layer 2 switch that provides users with 24

10/100Mbps Ethernet and 2 1000Mbps Gigabit ports. This Switch has SNMP management and
remote control capabilities such as “Web Cluster”. The Gigabit module, which can be copper or fiber
media, supports 1000BASE-SX, 1000BASE-LX or 1000BASE-T, allowing users to increase their
network response time at gigabit speeds and with great flexibility. A RS-232 serial port provides an
easy way for installation and initial set-up.

Non-blocking and maximum wire speed performances are designed on all ports. The Switch not only

supports Auto-Negotiation, but also Auto-MDIX function on all switched 24 10/100M RJ-45 ports
and two Gigabit Copper ports in both half or full duplex mode. The Auto-MDIX function makes it
convenient for the user, because it eliminates cabling on straight-line or cross-line issues.

24+2G switch provides a convenient way to operate Layer 2 management through the browser. The

User-friendly drop-down menu allows the user to easily learn, control and monitor. It supports not
only traditional SNMP function, but also RMON 1,2,3,9 groups for advanced network analysis. A
new management tool called “Single IP” is implemented here to provide the administrator an access
right to enter private IP domain through a single real IP. By this management tool, network manager
can remotely control his far-side servers in private IP domain without being there.

The Switch also supports both port-based VLAN and Tag-based. To increase bandwidth application,
it supports 7 groups with up to 4 ports Trunk, and moreover, these trunk ports provide fair-over
function to provide back up when one or more ports malfunction. A stacking mode is introduced
here to enhance the ability of VLAN. An integrated UI not only displays the link status of the
stacking sets, but also gives the easy way to set up their VLAN.

Totally front access design and full LED status display ease user’s installation and inspection and

maintenance efforts at rack mount environments. The extra LED display reflecting the fan status
allows for quick diagnosis of over-heat issues.

1.1 Unpacking

Open the shipping carton of the Switch and carefully unpack its contents, the carton should contain
the following items:

z One 24+2G, 24 port Fast Ethernet Layer 2 Switch.
z Mounting Kit: 2 mounting brackets and screws
z Four rubber feet with adhesive backing.
z One AC power cord.
z One RS-232 cable
z This User’s Guide (Disk or CD).

Note: to get the “Stacking” feature, please install th e optional Gigabit Module (purchased separately).

1.2 Installation

You can use the following guidelines when choosing a place to install the Switch.

z The surface must support at least 3 Kg of weight. Do not place heavy object on the Switch.
z Visually inspect the power cord and AC power connector.
z Make sure that there is proper heat dissipation form and adequate ventilation around the Switch.

Desktop or Shelf Installation:

When installing the Switch on the desktop of shelf, the rubber feet included with the device should
first be attached. Attach these cushioning feet on the bottom at each corner of the device. Allow
adequate space for ventilation between the device and the objects around it.

Rack Installation:

The 24+2G switch can be mounted in an ELA standard-sized, 19-inch rack, which can be placed in a
wiring closet with other equipment. To install, attach the mounting brackets on the switch side panels
(one on each side) and secure them with the screws provided. Then, use the screws provided with the
equipment rack to mount the switch on the rack.

- 8 -

Power on:

The 24+2G switch can be used with an AC power supply 90-260V AC, 50-60Hz. The AC power
connector is located at the rear of the unit. The switch’s power supply will adjust to the local power
source automatically and may be turned on without having any or all LAN segment cables connected.

After the power switch is turned on, the LED indicators should respond as fallows:

z All LED indicators will momentarily blink. This blinking of the LED indicators represents a

reset of the system.

z The power LED indicator will blink while the Switch loads onboard software and performs a

self-test. After approximately 20 seconds, the LED will light again to indicate the switch is in a
ready state.

z The Speed, Link/Activity LED indicator may remain ON or OFF depending on every port’s

situation.

z The fan LED will be vanished if fan works normally, or LED goes RED if fan stop

or failed.

1.3 Initial set up for management

There are two management ways can be chosen, one is out-of-band management, you work this way
with a PC and connect your PC and switch through RS232 cable. The other way is
in-band-management, you also work with a PC but connect your PC and switch through Ethernet
network no matter local or remotely, or simply directly connect your PC and switch through an
Ethernet cable. Before you activate the management function with the Switch, you have to read the
instructions below carefully and do some proper setting to insure you can access the switch through
your PC, then the switch devices will be replied or responded correctly as you wish.

1.3.1 out-of-band Terminal-mode Management

First, turn on your PC and execute with terminal mode program, such as, if you are in Microsoft
Window environment, you may choose “super terminal “from programs that are listed for
communication. Then follow the steps below:

Step 1: Set Hyper Terminal parameters on your PC

Bits Rate per second = 9600
Parity = None
Data Bits = 8

Stop Bit = 1

Flow Control = None

Step 2:

After setting the above on the PC, then connect your switch device with RS 232 cable, then type the
“enter” key, then, the device will response the Main Menu to you and ask you answer the username
and password. Then, Type the default value for the username and password to get further service, the
default username is” admin” and default password “123 “. To know more about operation in this
mode, please refer the instructions in chapter 4 of this manual to perform all function you want.

- 10 -

1.3.2 In-band management through Ethernet

In addition to terminal mode operation, 24+2G switch also supports in-band management through
browser, this function is much more user-friendly than terminal mode, because it can be operated
through mouse on the PC screen and moreover it can be performed either locally or remotely through
Ethernet.

Before you can access the switch, you have to know following things.

First you have to know the IP Address and Subnet Mask of both your switch and your PC. The
default value of the IP Address and Subnet Mask within the switch can be got through terminal
mode operation described in chapter 4, while the IP Address and Subnet Mask of PC can be found
in your PC system.

Second, in general, within a network, the members in the same network domain must have the same
Subnet IP unless there are routers between them, or, members in the same network domain can’t talk
to each others, so make sure the communication members in the same domain must have

different IP Addresses and same Subnet Mask.

Third, If there is a DHCP server in the network domain, be sure to enable the DHCP function both

on your PC and the switch, then save the setting and reboot the switch again (power-off-and–on once),
DHCP server and its protocol will automatically assign IP address and related IP Subnet Mask and
Default gateway, under this condition, you can execute your browser program in your PC and simply
type http:// IP-Address-of-switch to access the switch through Ethernet or over Internet. But if
there is no DHCP in the network, then you must follow the steps instructed below:

- 11 -

When there is no DHCP server in your network domain, according to the concept described above,
you must modify either the PC side or switch side to match the rule “the communication members
in the same domain must have different IP Addresses and same Subnet Mask. “, below, we try to
state the steps if we modify the content of IP configuration within the switch to match the domain
requirement of the PC:

Step 1: Get the IP configuration information in your PC

Step 2: Get IP configuration value used for switch from your network manager.

Get an IP Address for your switch, get IP Subnet Mask, and get default gateway IP address (if needed)
from your network manager.

Step 3: Modify the IP configuration value within the switch to match the rule

In the step 3, you must use the data that get from step 2 to modify the default value within the switch,
to achieve this, use terminal mode operation mentioned in 1.3.1. After modifying the IP address,
Subnet Mask, Default Gateway in the switch, then save the setting and execute the browser program
with http:// IP_Address_ of_ switch, then you may access the switch with following dialogue below.
Then type user name and password to get further service. To find out more operation in this mode,
please refer the instructions in chapter 3 of this manual.

- 12 -

1.3.3 Telnet management

In addition to local terminal mode operation, 24+2G switch supports remote management through
Telnet over network or even over Internet for that environment without browser. In this mode, user
also has to do the same setting as required in in-band management to the IP Configuration before
executing the Telnet program. Again, after proper setting to the switch, save the setting and connect
your Ethernet cable from your PC to any port of the Ethernet Switch, then you can simply typing as
following at the command line to access the switch:

Telnet IP_Address_of_Switch

The following dialogue below appears, type in user name and password to login. To find out more
operation in this mode, please refer the instructions in chapter 3 of this manual.

- 13 -

1.4 LED indicators information

There are many LEDs on the front panel of switch, after the power on, these LEDs will reflect the
current status truly within the switch, we explain below:

There is one power LED on the left side of front panel, whenever power is applied, it lights with
green, below it, there is Diagnostic LED, it will go blinking during the power-on diagnostics. There
are two more FAN status LEDs aside the power LEDs, the upper one indicate the left fan status inside
the switch, it vanishes when fan works normally, and will goes RED while fan is stop or with
malfunction, the lower one indicates the same for the fan at right side within the switch.

Each RJ-45 of 10/100M is with two LEDs built-in on its upper corner, left one indicates link status
and activity, while the right one indicates the speed information.

Each RJ-45 of 10/100/1000M for gigabit module (optional) is somewhat different. Upper yellow LED
indicates for 10M LINK, middle green LED indicates for 100M LINK, but for 1000M, or Gigabit,
both upper and middle LEDs are lit when gigabit port is link with other Gigabit port.

2.5.1. IP and Management mode

User can modify the switch IP Settings by filling with the new value, then clicks “apply” button to
confirm (save) his setting, then he/she must reboot switch, then new IP configuration value will be
activated.

The Management mode indicates which role this switch is currently playing. “Agent Slave” means it
is treated as a normal switch. “Agent Master” means the "Single IP" is activated and the switch is
treated as agent manager. ”Stacking slave” is used only when this switch is going to be a member of
stacking set. This setting will force the switch to activate spanning tree protocol and some VLAN
settings for preparation of stacking switches. “Stacking Master” does the same tasks too, but it
plays the role of manager of the whole stacking switches. Only the “Stacking Slave” can be added
into the members of a stacking set under one “Stacking master”. The default management mode is
"Agent Slave".

The extra “Agent IP” setting is necessary for the “Single IP” management. It defines the IP and the
subnet mask the master switch will be assigned, which are in the same IP domain as the managed

- 20 -

hosts’ one.

User can confine the “Single IP” function to local management by assigning the agent IP to the same
one as switch IP. Different from original IP forwarding method, it uses a method like webpage link
and won’t increase the loading of switch.

”Agent IP “setting and “Agent management” in the main menu will not show up if the agent mode is
set as “Slave”.

[Note] If any of the value is changed in this field, reboot is necessary.

2.5.2 Switch Setting

2.5.2.1 Advanced

 Miscellaneous Setting:

MAC Address Age-out Time: Type the number of seconds that an inactive MAC address remains in the

switch's address table. The valid range is 300~765 seconds. Default is 300 seconds.

Max bridge transit delay bound control: Limit the packets queuing time in switch. If enable, the
packets queued exceed will be drop. These valid values are 1sec, 2 sec, and 4 sec and off. Default is 1
seconds.

NOTE: Make sure of “Max bridge transit delay bound control” is enabled before enable Delay Bound,
because Enable Delay Bound must be work under “Max bridge transit delay bound control is enabled”
situation.

Broadcast Storm Filter: To configure broadcast storm control, enable it and set the upper threshold for
individual ports. The threshold is the percentage of the port's total bandwidth used by broadcast traffic.
When broadcast traffic for a port rises above the threshold you set, broadcast storm control becomes
active. The valid threshold value is 5%, 10%, 15%, 20%, 25% and off.

 Priority Queue Service settings:

First Come, First Serve: The sequence of packets sent is depending on arrive orders.

- 22 -

All High before Low: The high priority packets sent before low priority packets.

WRR: Weighted Round Robin. Select the preference given to packets in the switch's high-priority

queue. These options represent the number of high priority packets sent before one low
priority packet is sent. For example, 5 High：2 Low means that the switch sends 5 high-priority

packets before sending 2 low- priority packets.

Enable Delay Bound: Limit the low priority packets queuing time in switch. Default Max Delay

Time is 255ms. If the low priority packet stays in switch exceed Max Delay
Time, it will be sent. The valid range is 1-255ms.

Qos Policy: High Priority Levels: 0~7 priority level can map to high or low queue.

2.5.2.2 Misc Config

Collisions Retry Forever:

Disable – In half duplex, collision-retry maximum is 48 times and packet will be

dropped if collision still happen.

Enable – In half duplex, if happen collision will retry forever.

Hash Algorithm: Choose algorithms, CRC-Hash or DirectMap, to maintain MAC address table.
IFG Compensation: Enable or disab le inter-frame gap (IFG) compensation.

802.1x Protocol: Enable or disable 802.1x protocol.

- 23 -

2.5.3 Console Port Information

Console is a standard UART interface to communicate with Serial Port.

User can use windows HyperTerminal program to link the switch. Connect To -> Configure:

Bits per seconds: 9600
Data bits: 8
Parity: none
Stop Bits: 1
Flow control: none

2.5.4 Port Controls

User may modify or change mode operation in this page.

1. State: User can disable or enable this port control.

2. Auto Negotiation: User can set auto negotiation mode is Auto, Nway (specify the speed/duplex on

this port and enable auto-negotiation), Force of per port.

3. Speed:
User can set 100Mbps or 10Mbps speed on Port1~Port24.

User can set 1000Mbps, 100Mbps or 10Mbps speed on Port25~Port26 (depend on module card

mode).

4. Duplex: User can set full-duplex or half-duplex mode of per port.

5. Flows control:

Full: User can set flow control function is enable or disable in full mode.
Half: User can set backpressure is enable or disable in half mode.

6. Rate Control: port1 ~ port 24, supports by-port ingress and egress rate control. For example, assume

port 1 is 10Mbps, users can set its effective egress rate at 1Mbps and ingress rate at 500Kbps. Device
will perform flow control or backpressure to confine the ingress rate to meet the specified rate.

Ingress: Type the port effective ingress rate. The valid range is 0 ~ 1000. The unit is 100K.

0: disable rate control.
1 ~ 1000: valid rate value

Egress: Type the port effective egress rate. The valid range is 0~1000. The unit is 100K.

- 25 -

0: disable rate control.
1 ~ 1000: valid rate value.

7. Port Priority: Enable or disable the port priority function. There are two priorities (high or low)

provided if port priority is enabled.

8. Port Security: A port in security mode will be “locked” without permission of address learning. Only

the incoming packets with SMAC already existing in the address table can be forwarded normally.
User can disable the port from learning any new MAC addresses, then use the static MAC addresses
screen to define a list of MAC addresses that can use the secure port. Enter the settings, then click
Apply button to change on this page.

2.5.5 Trunking

The Link Aggregation Control Protocol (LACP) provides a standardized means for exchanging
information between Partner Systems on a link to allow their Link Aggregation Control instances to reach
agreement on the identity of the Link Aggregation Group to which the link belongs, move the link to that
Link Aggregation Group, and enable its transmission and reception functions in an orderly manner. In
conclusion, Link aggregation lets you group up to eight consecutive ports into a single dedicated
connection. This feature can expand bandwidth to a device on the network. LACP operation requires
full-duplex mode, more detail information refers to IEEE 802.3ad

2.5.5.1 Aggregator setting

1. System Priority: A value used to identify the active LACP. The switch with the lowest value has the

highest priority and is selected as the active LACP. Valid value is 1~65535.

2. Group ID: There are seven trunk groups to provide configure. Choose the "group id" and click

"Get".

3. LACP: If enable, the group is LACP static trunking group. If disable, the group is local static

trunking group. All ports support LACP dynamic trunking group. If connecting to the device that also

- 27 -

supports LACP, the LACP dynamic trunking group will be created automatically.

4. Work ports: Allow max four ports can be aggregated at the same time. If LACP static trunking

group, the exceed ports is standby and able to aggregate if work ports fail. If local static trunking
group, the number must be as same as the group member ports.

5. Select the ports to join the trunking group. Allow max four ports can be aggregated at the same time.

6. If LACP enable, you can configure LACP Active/Passive status in each port on State Activity page.

7. Click Apply.

2.5.5.2 Aggregator Information

When you are setting LACP aggregator, you can see relation information in here.

1. This page is no group active. LACP don’t working.

2. This page is Static Trunking groups.

3. This page is Actor and Partner trunking one group.

- 28 -

2.5.5.3 State Activity

Active (select): The port automatically sends LACP protocol packets.
N/A (no select): The port does not automatically sends LACP protocol packets, and responds only if it

receives LACP protocol packets from the opposite device.

1. A link that has either two active LACP ports or one active port can perform dynamic LACP trunking.

A link has two N/A LACP ports will not perform dynamic LACP trunking because both ports are
waiting for and LACP protocol packet from the opposite device.

2. If you are active LACP’s actor, when you are select trunking port, the active status will be created

automatically.

2.5.6 Filter Database

2.5.6.1. IGMP Snooping

The 24+2G switch supports multicast IP. One can enable IGMP protocol on this web page, and then
display the IGMP snooping information on this page. There are all multicast groups, VIDs and member
ports in the list. IP multicast addresses range from 224.0.0.0 through 239.255.255.255.

The Internet Group Management Protocol (IGMP) is an internal protocol of the Internet Protocol (IP)
suite.
IGMP can manage the multicast traffic if the members (switches, router or other network devices) of
group support IGMP. With IGMP enable, the member ports will detect IGMP queries, report packets and
manage the IP mu lticast traffic through the switch.
IGMP have three fundamental types of message as follows:

Message Description

Query

A message sent from the queries (IGMP router or switch) asking for a
response from each host belonging multicast group.

Report

A message sent by a host to the queries to indicate that the host wants to be or
is a member of a given group indicated in the report message.

Leave Group

A message sent by a host to the queries to indicate that the host has quit being
a member of a specific multicast group.
