Physical Dimension

The physical dimension of 24 10/100TX + 2 10/100/1000T/ Mini-GBIC Combo Managed PoE Switch is 440mmx 280mm x 44mm (W x D x H)

Front Panel

The front panel of the 24 10/100TX + 2 10/100/1000T/ Mini-GBIC Combo Managed PoE Switch consists of 24x 10/100Base-TX RJ-45 ports (Auto MDI/MDIX), 2 auto-detected Gigabit Copper/Mini-GBIC ports, and one console port. The LED Indicators are also located on the front panel of the Switch.

Front panel of the 24 10/100TX + 2 10/100/1000T/ Mini-GBIC Combo Managed PoE Switch

 RJ-45 Ports (Auto MDI/MDIX): 24x 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.

 2 Giga port: Traditional RJ-45 ports can be used for uplinking wide-band paths in

short distance (< 100 m), or the appropriate replaceable mini-GBIC ports can be used for the application of wideband uplinking and long distance transmissions to fit the field request flexibly.

LED Indicators

The LED indicators display a real-time indication of systematic operation status. There are three LED-Indicators (Link/Activity, Full duplex, PoE) for each UTP port and one power LED for the system unit. The following table provides descriptions of the LED statuses and meaning.

The rear panel of the 24 10/100TX + 2 10/100/1000T/ Mini-GBIC Combo Managed PoE Switch

Desktop Installation

Set the switch on a sufficiently large flat space with a power outlet nearby. The surface where you put your 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 switch come with a rack-mounted 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 attaching both mounting brackets, position the 24 10/100TX + 2 10/100/1000T/ Mini-GBIC Combo Managed PoE 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.

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 of 50~60Hz. Check the power indicator on the front panel to see if power is properly supplied.

Network Application

This section provides a few samples of network topology in which the switch is used. In general, the 24 10/100TX + 2 10/100/1000T/ Mini-GBIC Combo Managed PoE Switch with its large address table (8K MAC address) and high performance are ideal for interconnecting networking segments.

PC, workstations, and servers can communicate each other by directly connecting with 24 10/100TX + 2 10/100/1000T/ Mini-GBIC Combo Managed PoE Switch. The switch automatically learns node addresses, which are subsequently used to filter and forward all traffic based on the destination address.

24 10/100TX + 2 10/100/1000T/ Mini-GBIC Combo Managed PoE Switch provides PoE injector function on every Ethernet port which can provide the power to the PD device, such as AP or switch. It can solve the problem of the PD device position limitation of power supply.

Using Uplink port, the Switch can connect with another switch or hub to interconnect other small-switched workgroups to form a larger switched network. Meanwhile, you can also use fiber ports to connect switches.

Small Workgroup

24 10/100TX + 2 10/100/1000T/ Mini-GBIC Combo Managed PoE Switch can be used as a standalone switch to which personal computers, server, printer server, are directly connected to form a small workgroup.

Small Workgroup Application

Segment workgroup

For enterprise networks where large data broadcasts are constantly processed, this switch is an ideal solution for department users to connect to the corporate backbone.

In the illustration below, two managed PoE switches with PCs, print server, local server, wireless AP (IEEE 802.3af compliant), and IP camera (IEEE 802.3af compliant) attached are both connect to the core switch. All the devices in this network can communicate with each other through the core switch.

Segment workgroup Application

Console Management

Connecting to the Switch

The console port is a female DB-9 connector that enables a connection to a PC or terminal for monitoring and configuring the Switch. Use the supplied RS-232 cable with a male DB-9 connector to connect a terminal or PC to the Console port. The Console configuration (out of band) allows users to set switch for remote terminal as if the console terminal were directly connected to it.

When the connection between switch and PC is ready, turn on the PC and run a terminal emulation program or Hyper Terminal and configure its communication

parameters to match the following default characteristics of the console port:

Baud Rate: 9600 bps Data Bits: 8 Parity: none Stop Bit: 1 Flow control: None

The settings of communication parameters

After finishing the parameter settings, click “OK“. When the blank screen shows up, press Enter key to bring out the login prompt. Key in the ‘root’ (default value) for the both User name and Password (use Enter key to switch), then press Enter key and

the Main Menu of console management appears right after as below. The figure shown below is a login screen:

Web-Based Management

This section introduces the configuration and functions of the Web-Based management.

About Web-based Management

On the CPU board of the switch there is an embedded HTML web site residing in flash memory, which offers advanced management features and allow users to manage the switch from anywhere on the network through a standard browser such as Microsoft Internet Explorer.

The Web-Based Management supports Internet Explorer 6.0. And, it is applied with Java Applets for reducing network bandwidth consumption, enhance access speed and present an easy viewing screen.

Preparing for Web Management

Before starting web management, user can use console to log in the switch for checking the default IP of the switch. Please refer to Console Management Chapter for console login. If user needs change IP address in first time, please use console mode to modify it. The default value is shown as below:

IP Address: 192.168.16.1 Subnet Mask: 255.255.255.0 Default Gateway: 192.168.16.254 User Name: root Password: root

System Login

1. Launch the Internet Explorer on the PC

2. Key in “http:// “+” the IP address of the switch”, and then Press “Enter”.

Uniform Resource Locator

3. The login screen appears right after.

4. Key in the user name and password. The default user name and password are the same as ‘root’

5. Press Enter or click OK button, and then the home screen of the Web-based management shows up.

once the device exceed the input data rate of another device as a result the receiving device will send a PAUSE frame which halts the transmission of the sender for a specified period of time. When disabled, the receiving device will drop the packet if too much to process.

 Back Pressure: Set Back Pressure as ON or OFF in Half Duplex mode.  Band Width: All ports support port ingress and egress rate control. For example,

assume the wire speed of port 1 is 100Mbps; users can set its effective egress rate as 2Mbps, ingress rate as 1Mbps. The switch will perform Flow Control or Back Pressure to confine the ingress rate to meet the specified rate. ¾ In: Key in the port effective ingress rate. The valid range is from 0 ~ 999. 0

means rate control is disabled. ¾ Out: Key in the port effective egress rate. The valid range is from 0 ~ 999. 0

means rate control is disabled.

 Priority: The static priority is based on port. If the port is set as high priority,

income frames from the port always are high priority frame.

 Security: When the port is in security mode, the port will be “locked” without

permission of address learning. Only the incoming packets with static MAC already existing in the address table can be forwarded normally. User can disable the port from learning any new MAC addresses, and then use the static MAC

addresses function to define a list of MAC addresses that can access to secure port.

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. Link aggregation lets you group up to 4 ports into one dedicated connections. 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.

 LACP: When enabled, the trunk group is using LACP. A port which joins an LACP

trunk group has to make an agreement with its member ports first. When disabled, the trunk group is a static trunk group. The advantage of having the LACP disabled is that a port joins the trunk group without any handshaking with its member ports. But member ports won’t know that they should be aggregated together to form a logic trunk group.

 Work ports: This column field allows the user to type in the total number of active

port up to four. With LACP trunk group, you create a trunk group by connecting two or more switches (e.g. you assign four ports to be the members of the trunk group whose work ports column field is set as two). The exceed ports are standby (the Aggregator Information tab will show standby status on the exceed ports) and can be aggregated if work ports fail. If it is a static trunk group, the number of work ports must equal the total number of group member ports.

Forwarding and Filtering

IGMP Snooping

The Internet Group Management Protocol (IGMP) is an internal protocol of the Internet Protocol (IP) suite. IP manages multicast traffic by using switches, routers, and hosts that support IGMP. Enabling IGMP allows the ports to detect IGMP queries, report packets, and manage IP multicast traffic through the switch. IGMP have three fundamental types of message shown as follows:

Message Description

Query

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

Report

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

The switch supports IP multicast. You can enable IGMP protocol via setting the IGMP Configuration page to see the IGMP snooping information. IP multicast addresses are in the range of 224.0.0.0 through 239.255.255.255.

VLAN configuration

A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain, which would allow you to isolate network traffic, so only the members of the same VLAN will receive traffic from the ones of the same VLAN. Basically, creating a VLAN from a switch is logically equivalent of reconnecting a group of network devices to another Layer 2 switch. However, all the network devices are still plugged into the same switch physically.

The switch supports Port-based and 802.1Q (tagged-based) VLAN. The default configuration of VLAN operation mode is “Disable”.

[NOTE] To reboot the switch when the VLAN mode is changed

Port-based VLAN

Packets can go among only members of the same VLAN group. Note all unselected ports are treated as belonging to another single VLAN. If the port-based VLAN enabled,

the VLAN-tagging is ignored.

In order for an end station to send packets to different VLAN groups, it itself has to be either capable of tagging packets it sends with VLAN tags or attached to a VLAN-aware bridge that is capable of classifying and tagging the packet with different VLAN ID based on not only default PVID but also other information about the packet, such as the protocol.

802.1Q VLAN

Tagged-based VLAN is an IEEE 802.1Q specification standard. Therefore, it is possible to create a VLAN across devices from different switch venders. IEEE 802.1Q VLAN uses a technique to insert a “tag” into the Ethernet frames. Tag contains a VLAN Identifier (VID) that indicates the VLAN numbers.

You can create Tag-based VLAN, and enable or disable GVRP protocol. There are 256 VLAN groups to provide configuration. Enable 802.1Q VLAN, all ports on the switch belong to default VLAN of VID 1. The default VLAN can’t be deleted.

GVRP (GARP VLAN Registration Protocol) is a protocol that facilitates control of virtual local area networks (VLANs) within a larger network. GVRP conforms to the IEEE

802.1Q specification, which defines a method of tagging frames with VLAN configuration data. This allows network devices to dynamically exchange VLAN configuration information with other devices. GVRP is based on GARP (Generic Attribute Registration Protocol), a protocol that defines procedures by which end stations and switches in a local area network (LAN) can register and de-register attributes, such as identifiers or addresses, with each other. Every end station and switch thus has a current record of all the other end stations and switches that can be reached.

Spanning Tree

The Spanning-Tree Protocol (STP) is a standardized method (IEEE 802.1d) for avoiding loops in switched networks. When STP enabled, to ensure that only one path at a time is active between any two nodes on the network. It’s recommended to enable STP on all switches to ensure only one active path on the network. The Rapid Spanning Tree Protocol (RSTP) is an evolution of the Spanning Tree Protocol and provides for faster spanning tree convergence after a topology change. The system also supports STP and the system will auto-detect the connected device that is running STP or RSTP protocol.

Troubleshooting

This section is intended to help solve the most common problems on the 24 10/100TX + 2 10/100/1000T/ Mini-GBIC Combo Managed PoE Switch.

Incorrect connections

The switch port can automatically detect straight or crossover cable when the user links the switch with other Ethernet device. For the RJ-45 connector should use correct UTP or STP cable, 10/100Mbps ports use 2 pairs twisted cable. If the RJ-45 connector is not correctly pinned on right position, 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.



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 shielded twisted-pair (STP)

cable for RJ-45 connections: 100Ω Category 3, 4 or 5 cable for 10Mbps connections, 100Ω Category 5 cable for 100Mbps connections, or 100Ω Category 5e/6 cable for 1000Mbps connections. Also be sure that the length of

any twisted-pair connection does not exceed 100 meters (328 feet).



Improper Network Topologies

It is important to make sure that the network topology is valid. Common topology faults include excessive cable length and too many repeaters (hubs) between end nodes. In addition, the user should make sure that the 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 the network performance.

Diagnosing LED Indicators

To assist in identifying problems, the switch can be easily monitored through panel indicators, which describe common problems the user may encounter and where the user can find possible solutions.

If the power indicator does turn on when the power cord is plugged in, the user may 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 solved, please contact the local dealer for assistance.
