VDSL Solution

The VDSL IP DSLAM networking solution delivers cost-effective, high-performance broadband access to multiunit buildings (hotels, apartment, and multi-tenant unit office buildings) and enterprise campus environments such as manufacturing, educational campuses, and medical facilities. VDSL technology dramatically extends Ethernet over existing Category 1/2/3 wiring at speeds from 4/1,5/10/15 Mbps (full duplex) and distances up to 1900/1500/1200/1000 meters. The VDSL technology delivers broadband service on the same lines as Plain Old Telephone Service (POTS), digital telephone, and ISDN system. In addition, VDSL supports modes compatible with symmetric digital subscriber line, allowing service providers to provision VDSL to buildings where broadband services already exist.

The VDSL solution includes 8+2E Managed IP DSLAM (CO side), and VDSL converter as CPE device.

The VDSL solution delivers everything needed to quickly deploy an Ethernet-based network with the performance required to deliver high-speed Internet access at much greater distances and drive services like IP telephony and audio/video streaming. With this technology, a broad range of customers can benefit from lower operating costs and rapid deployment. The VDSL solution provides multicast, Layer 2 quality of service (QoS), Link Aggregation (LACP) dynamic trunking group, security, GVRP, IGMP for VOD (Video on demand) and SNMP RMON management and Web-based Switch network management.

The VDSL IP DSLAM is a bridge between external Internet backbone through a router for IP sharing and the building 110D telephone rack or telephone box. It utilizes the available telephone wire to enable high-speed Internet access to building residents.

The IP DSLAM uses the phone line networking technology endorsed by the VDSL (Very High Data Rate DSL), and the IP DSLAM utilizes the already existing telephone wire to deliver 4/1,5/10/15 Mbps Internet access on each RJ-45 port. This gives users a low-cost, end-to-end solution and eliminates the need to train installation teams on multiple systems.

8+2E Managed 4/1, 5/10/15M VDSL + 2 10/100M Fast Ethernet

The IP DSLAM has 8x 4/1, 5/10/15M VDSL ports and 2 x 10/100M Ethernet ports. The switches is one rack-unit (1RU) high, 10-inches deep. It is a standard Rack mounted size.

IP DSLAM deliver dedicated bandwidth per port at rates of 4/1,5/10/15 Mbps. VDSL transmissions coexist with POTS and ISDN, and can be compatible with ADSL/HomePNA traffic in the same building. The switches can be configured on a per-switch basis to support the following modes:

•

4/1 Mbps asymmetrical rate (up to 1900 meters)

•

5 Mbps symmetrical rate (up to 1500 meters)

•

10 Mbps symmetrical rate (up to 1200 meters)

•

15 Mbps symmetrical rate (up to 1000 meters)

The VDSL IP DSLAM and VDSL Modem provide fast and easy connectivity into building patch panels with RJ-45 connector. The 10/100 Ethernet ports can be used to connect servers, Ethernet switches. These connectivity options provide multiple price/performance options to meet building and budget requirements.

3.Installation Hardware Installation

This chapter describes how to install the IP DSLAM. To established network connection. You may install the IP DSLAM on any level surface (table, shelf, 19 inch rack or wall mounting). However, please take note of the following minimum site requirements before you begin.

Pre-Installation Requirements

Before you start actual hardware installation, make sure you can provide the right operating environment, including power requirements, sufficient physical space, and proximity to other network devices that are to be connected. Verify the following installation requirement:

•

Power requirements: AC 100V to 240 V at 50 to 60 Hz.

The Switch power supply automatically adjusts to the input voltage level.

•

The IP DSLAM should be located in a cool dry place, with at least 10cm/4in of space at the front and back for

ventilation.

•

Place the IP DSLAM out of direct sunlight, and away from heat sources or areas with a high amount of

electromagnetic interference.

•

Check if network cables and connectors needed for installation are available.

General Rules

Before making any connections to the IP DSLAM, note the following rules:

Ethernet Port (RJ-45)

All network connections to the IP DSLAM Ethernet port must be made using Category 5 UTP for 100Mbps and Category 3,4 UTP for 10Mbps. No more than 100 meters (about 328 feet) of cabling may be use between IP DSLAMs or with HUB or an end node.

•

VDSL Port (RJ-45)

All home network connections to the VDSL Port made using 18 ~ 26 Gauge phone wiring.

•

We do not recommend using 28 Gauge or above phone line.

Connecting the IP DSLAM

The IP DSLAM has 2 10/100 Mbps N-way ports which support connection to 10Base-T Ethernet or 100Base-TX Fast Ethernet. Support full or half-duplex operation. The transmission mode is using auto-negotiation. Therefore, the devices attached to these ports must support auto-negotiation unless they will always operate at half duplex. If transmissions must run at full duplex, but the attached device does not support auto-negotiation, then you should upgrade this device to a newer version that supports auto-negotiation. Use “T” port to connect to devices such as a cable modem, server, bridge or router. You can also cascade to another compatible MUX or hub by connecting the UP-Link port to an “MDI” port (e.g., port TX on this switch) on the other device.

Connecting “MDI-X” Station Port

1. You can connect the “T” port on the IP DSLAM to any device that uses a standard network interface such as a Cable modem, ADSL modem, Ethernet Switch, workstation or server, or also to a network interconnection device such as

a bridge or router (depending on the port type implemented).

2. Prepare the network devices you wish to connect. Make sure you have installed suitable VDSL Modem before making a connection to any of the IP DSLAM (1-8) station ports. You also need to prepare 18 ~ 26 gauge one twist pair phone Line wiring with RJ-45 plugs at both ends.

3. Connect one end of the cable to the RJ-45 port of the Home Access network adapter, and the other end to any

available (1~8) station port on the VDSL. Every port supports 10 Mbps connections. When inserting an RJ-45 plug, be sure the tab on the plug clicks into position to ensure that it is properly seated.

Do not plug a RJ-11 phone jack connector into the Ethernet port (RJ-45 port). This may damage the VDSL.

Instead, use only twisted-pair cables with RJ-45 connectors that conform the FCC standards.

Note:

1. Be sure each twisted-pair cable (RJ-45) is not over by 100 meters (328 feet).

2. RJ-45 port use 18 ~ 26 gauge phone wiring, 28 gauge or above is not recommended.

3. We advise using Category 5 cable for Cable Modem or router connections or to attach to any high bandwidth device to avoid any confusion or inconvenience.

Connecting “MDI” Port (TX)

Prepare straight through shielded or unshielded twisted-pair cables with RJ-45 plugs on both ends. Use 100Ω Category

5 cable for connections. Connect one end of the cable to “TX” port of the IP DSLAM, and the other end to a standard RJ-45 station port on cable modem, ADSL router, wireless bridge, etc. When inserting an RJ-45 plug, be sure the tab on the plug clicks into position to ensure that it is properly seated.

Note:

Make sure the length of the twisted-pair cable is not over by 100 meters (328 feet).

2-4-2-2.Advanceed

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. This valid value are 1sec, 2 sec, 4 sec and off. Default is 2 seconds.

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 are 5%, 10%, 15%, 20%, 25% and off.

Priority Queue Service settings:

First Come First Service: The sequence of packets sent is depend on arrive order. All High before Low: The high priority packets sent before low priority packets. 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 packet.

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 1~255 ms.

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.

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

Protocol Enable Setting:

Enable Spanning Tree Protocol: Default recommend to enable STP Enable Internet Group Multicast Protocol: enable IGMP protocol VLAN Protocol: 802.1Q(Tagging Based) without GVRP VLAN mode

802.1Q(Tagging Based) with GVRP VLAN mode

GVRP (GARP [Generic Attribute Registration Protocol] VLAN Registration Protocol)

GVRP allows automatic VLAN configuration between the switch and nodes. If the switch is connected to a device with GVRP enabled, you can send a GVRP request using the VID of a VLAN defined on the switch, the switch will automatically add that device to the existing VLAN.

•

Assign management IP address to specific VLAN

Can limit management system only for specific VLAN, This function must enable 802.1Q.

•

Auto Speed SNR margin value setup: Maximum Minimum

VDSL Speed auto adaptive function is based on SNR value, you can specify target SNR margins. Maximum: When SNR value bigger than Maximum value, VDSL speed will increase. Minimum: When SNR value smaller than Minimum value, VDSL speed will decrease. Priority of Minimum setup is higher than Maximum setup.

•

Interleaver depths

The Interleaving function reorganizes the bytes of the VDSL frames, dispersing them throughout the frames over the line. As a result, impulse noise that would normally appear sequentially, is spread over several frames. This enables correction of a greater number of errors than would be possible if the bytes had been concentrated in a single frame. The protected portion of the VDSL frame can be passed through a convolutional interleaver/deinterleaver. This protects the data, together with the RS coding, from impulse noise with a duration of up to 300 µs at full rate. The total latency of the device consists of the latency caused by the RS encoding and the delay caused by interleaving. The parameter M is used to define the length of protection supported by the interleaving function. The value of if0le defines no use of the interleaver and the maximum value of 16 defines the maximum protection. The values 0,1,2,8 and 16 are valid. The registers M_TX and M_RX are used for the depth of the interleaver.

4.2.2-4-3. Console Port Information

1. 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

4.2.2-4-4. VDSL Speed Control and port Enable/Disable

This section shows you how to change every port status and speed mode State: You can disable or enable VDSL port control Auto Negotiation: You can set enable or disable VDSL port Speed: You can change VDSL Speed mode by 4/1Mbps, 5Mbps, 10Mbps or 15Mbps Speed Default Value: 10 Mbps Distance between VDSL & VDSL modem when standard 24 Gauge 0.5mm cable is used: 4/1Mbps -> 1.9 Km. 5 Mbps -> 1.5 km. 10 Mbps -> 1.2 km. 15 Mbps -> 1.0 km. Duplex: User can set full-duplex or half-duplex mode of per port. Flow Control: Full: User can set flow control function is enable or disable in hull mode.

Half: User can set backpressure is enable or disable in half mode.

Change Speed procedures:

a. Confirm the VDSL port is linking which you want to change the speed mode. b. Make sure VDSL port has been connecting to VDSL Modem and Link up OK. c. Select the port(there are 8+2E Managed available) d. Select the speed mode e. Click “Apply” to confirm the settings f. The VDSL port will link down

g. Await 20 seconds the VDSL port will link up again with the new speed mode. When the VDSL is linked up with the VDSL modem, both speed modes will be changed correspondingly. If the VDSL is not linked up with the VDSL modem, only the speed mode of the port selected from VDSL will be changed.

*Note: We do not suggest to change speed, unless necessary. Both VDSL IP DSLAM & VDSL modem must be in the

same speed mode in order to be linked up successfully.

4.2.2-4-5. Link Aggregation

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.

full-duplex mode, more detail information refer to IEEE 802.3ad.

2-4-5-1. Aggregator setting

LACP operation requires

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.

1.Group ID: you can create a link aggregation across two or more ports, choose the "group id" and click "Get".

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

3. Work ports: The max number of 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 the same as group ports.

4. Select the ports to join the trunking group

5. If LACP enable, you can configure LACP Active/Passive status in each ports

6. Click Apply.

2-4-5-2. Aggregator Information

When you are setting LACP aggregator, you can see relation information in here. This page is Actor and Partner trunking one group with port 1 to port 1.

2-4-5-3. State Activity

Active (select): The port automatically sends LACP protocol packets. Passive (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 having either two active LACP ports or one active port can perform dynamic LACP trunking. A link has two passive 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.

4.2.2-4-6. Filter Database

2-4-6-1. IGMP Snooping

The IP DSLAM support IP multicast, you can enable IGMP protocol on web management’s switch setting advanced page, then display the IGMP snooping information in this page, you can view difference multicast group, VID and member port in here, 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. IP manages multicast traffic by using switches, routers, and hosts that support IGMP. Enabling IGMP allows the ports to detect IGMP queries and report packets and manage IP multicast 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

Report

Leave Group

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

2-4-6-2. Static MAC Address

When you add a static MAC address, it remains in the switch's address table, regardless of whether the device is physically connected to the switch. This saves the switch from having to re-learn a device's MAC address when the disconnected or powered-off device is active on the network again.

1. To add a static MAC address

2. From the main menu, click administrator, then click Filter Database.

3. Click Static MAC Addresses. In the MAC address box, enter the MAC address to and from which the port should permanently forward traffic, regardless of the device's network activity.

4. In the Port Number box, select a port number.

5. If tag-based (IEEE 802.1Q) VLANs are set up on the switch, static addresses are associated with individual VLANs. Type the VID (tag-based VLANs) to associate with the MAC address.

6. Click “add”

2-4-6-3. 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 Submit to apply the changes on this page.

2-4-6-4. MAC filtering

MAC address filtering allows the switch to drop unwanted traffic. Traffic is filtered based on the destination addresses. For example, if your network is congested because of high utilization from one MAC address, you can filter all traffic transmitted from that MAC address, restoring network flow while you troubleshoot the problem.

4.2.2-4-7. VLAN configuration

A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows you to isolate network traffic so only members of the VLAN receive traffic from the same VLAN members. 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 plug into the same switch physically.

The IP DSLAM supports port-based and protocol-base VLAN in web management page, In the default configuration, VLAN support is enable and all ports on the switch belong to default VLAN, VID is 1.

Support Multiple VLAN (IEEE 802.1Q VLAN)

Port-based Tagging rule 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.

Support Protocol-based VLAN

In order for an end station to send packets to different VLAN, 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.

IP DSLAM will support protocol-based VLAN classification by means of both built-in knowledge of layer 2 packet formats used by selected popular protocols, such as Novell IPX and AppleTalk’s EtherTalk, and some degree of programmable protocol matching capability.

2-4-7-1. Basic

Create a VLAN and add tagged member ports to it.

1. From the main menu, click administrator -- VLAN configuration.

2. Click “Add”

3. Type a name for the new VLAN.

4. Type a VID (between 2-4094). The default is 1.

5. From the Available ports box, select ports to add to the switch and click Add.

6. Click “Apply”.

2-4-7-2. Port VID

Configure port VID settings

From the main Tag-based (IEEE 802.1Q) VLAN page, click Port VID Settings.

Port VID (PVID)

Sets the Port VLAN ID that will be assigned to untagged traffic on a given port. For example, if port 10's Default PVID is 100, all untagged packets on port 10 will belong to VLAN 100. The default setting for all ports is VID 1. This feature is useful for accommodating devices that you want to participate in the VLAN but that don't support tagging. Only one untagged VLAN is allowed per port.

Ingress Filtering

Ingress filtering lets frames belonging to a specific VLAN to be forwarded if the port belongs to that VLAN. IP DSLAM has two ingress filtering rule as follows: Ingress Filtering Rule 1:Forward only packets with VID matching this port's configured VID Ingress Filtering Rule 2:Drop Untagged Frame

4.2.2-4-8. 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. You can enable Spanning-Tree Protocol on web management’s switch setting advanced item, select enable Spanning-Tree protocol. We are recommended that you enable STP on all switches ensures a single active path on the network.

1. You can view spanning tree information about the Root bridge as following screen:

value, you must reboot the switch.

4.2.2-4-9. Port Sniffer

The Port Sniffer is a method for monitor traffic in switched networks. Traffic through ports can be monitored by one specific port. That is, traffic goes in or out monitored ports will be duplicated into sniffer port.

Roving Analysis State: Enable or disable the port sniffer function. Analysis Port: Analysis port can be used to see all monitor port traffic. You can connect sniffer port to LAN Analysis,

Session Wall or Netxray.

Monitor Ports: The ports you want to monitor. All monitor port traffic will be copied to sniffer port. You can select max 9

monitor ports in the switch. If you want to disable the function, you must select monitor port to none.

Monitor Rx: Monitored receive frames from the port. Monitor Tx: Monitoring sent frames from the port.

4.2.2-4-10. SNMP

Any Network Management running the Simple Network Management Protocol (SNMP) can management the switch, Provided the Management Information Base (MIB) is installed correctly on the management station. The SNMP is a Protocol that governs the transfer of information between management and agent. The VDSL SWITH support SNMP V1.

5. Applications

The VDSL provides home network architecture. Transforming an apartment into a Multiple-Family Home network area, sharing a single internet account for multiple users via Router & Cable Modem, it can provide unlimited access time in the internet at a reasonable low price.

Bridging Functions – The IP DSLAM provides full transparent bridging function. It automatically connects node

addresses, that are later used to filter and forward all traffic based on the destination address. When traffic passes between devices attached to the shared collision domain, those packets are filtered from the IP DSLAM. But when traffic must be passed between unique segments (i.e., different ports of the IP DSLAM), a temporary link is set up between the IP DSLAM’s port in order to pass this traffic, via the high-speed VDSL fabric.

T ransceiver function

The IP DSLAM support Ethernet to VDSL convert, It can be transmit or receive packet from Ethernet port to the RJ11 port. Or VDSL port to Ethernet port.

Flexible Configuration–The IP DSLAM is not only Designed to segment your network, but also to provide a wide

range of options in the configuration of Home network connections. It can be used as a simple stand-alone IP DSLAM; or can be connected with another IP DSLAM, Cable modem, Router, XDSL, ISDN, gateway or other network interconnection devices in various configurations. Some of the common applications of the IP DSLAM are described in this chapter.

*Application for Video on demand and Vi deo confere nc e

Used as apartment for Internet access

The IP DSLAM provides a high speed, 10Mbps transmission over existing home telephone wiring over a single Internet account to provide simultaneous independent Internet access to multiple users. No matter ISDN Telephone system nor POTS Telephone system you have, the VDSL Technology let you can use the telephone system and VDSL network system in the same time.

Figure Chapter 4.1

Application for Sharing a single internet account

If multiple users would like to share a single internet account using the IP DSLAM, which is to be connected to a IP sharing device, then to a xDSL or Cable Modem.

Note:

For network applications that actually require Router (e.g., Interconnecting dissimilar network types), attaching the IP DSLAM directly to a router can significantly improve overall home networking performance.

High bandwidth backbone ready

The IP DSLAM provides 10/100Mbps auto sensing for external trunk device (Fiber optics, Wireless Bridge, xDSL & other WAN services)

Appendix A: Troubleshooting

Diagnosing VDSL Indicators

The VDSL can be easily monitored through its comprehensive panel indicators. These indicators assist the network manager in identifying problems the IP DSLAM may encounter. This section describes common problems you may encounter and possible solutions

1. Symptom: POWER indicator does not light up (green) after power on.

Cause: Defective power outlet, power cord, internal power supply

Solution: Cheek the power outlet by trying another outlet that is functioning properly. Check the power cord with

another device. If these measures fail to resolve the problem, have the unit power supply replaced by a qualified distributor.

2. Symptom: Link indicator does not light up (green) after making a connection.

Cause: Network interface (e.q., a network adapter card on the attached device), network cable, or switch port is

defective.

Solution: 2.1 Verifies the switch and attached device are powered on.

2.2 Be sure the cable is plug into both the switch and corresponding device.

2.3 Verify that the proper cable type is used and its length does not exceed specified limits.

2.4 Check the adapter on the attached device and cable connections for possible defects.

2.5 Replace the defective adapter or cable if necessary.

3. Symptom: VDSL Link can not be established.

Cause: Rusted phone wire, not standard 24 gauge phone wire, not twisted-pair phone wire, wrong speed mode.

Solution: Check if speed of CO and CPE is in the same speed mode else please increase interleaver depth value

to 8 or above. ve.

System Diagnostics

Power and Cooling Problems

If the POWER indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply as explained in the previous section. However, if the unit should turn itself off after running for a while, check for loose power connections, power loss or surges at the power outlet, and verify that the fan on back of the unit is unobstructed and running prior to shutdown. If you still cannot isolate the problem, then the internal power supply may be defective. In this case, contact your supplier for assistance.

Installation

Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (e.g., the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.

T ransmission Mode

The selections of the transmission mode for the RJ-45 ports are auto-negotiation using the default method. Therefore, if

the Link signal is disrupted (e.g., by unplugging the network cable and plugging it back in again, or by resetting the power), the port will try to reestablish communications with the attached device via auto-negotiation. If auto-negotiation fails, then communications are set to half duplex by default. Based on this type of industry-standard connection policy, if you are using a full-duplex device that does not support auto-negotiation, communications can be easily lost (i.e., reset to the wrong mode) whenever the attached device is reset or experiences a power fluctuation. The best way to resolve this problem is to upgrade these devices to version that will support auto-negotiation.

Cabling

1. Verify that the cable type is correct. Be sure RJ-45 cable connectors are securely seated in the required ports. Use

100Ω straight-through cables for all standard connections. Use Category 5 cable for 100Mbps Fast Ethernet

connections, or Category 3, 4 or 5 cables for standard 10Mbps Ethernet connections. Be sure RJ-11 phone wiring, use 18~26 gauge.

2. Make sure all devices are connected to the network. Equipment any have been unintentionally disconnected from the network.

3. When cascading two devices using RJ-45 station ports at both ends of the cable (i.e., not an MDI port), make sure a crossover cable is used. Crossover cable should only be used if a MDI port is not available.

Physical Configuration

If problems occur after altering the network configuration, restore the original connections, and try to track the problem down by implementing the new changes, one step at a time. Ensure that cable distances and other physical aspects of the installation do not exceed recommendations

System Integrity

As a last resort verify the switch integrity with a power-on reset. Turn the power to the switch off and then on several times. If the problem still persists and you have completed all the preceding diagnoses, contact your dealer for assistance.
