2. Overview

2.1 Introduction

LPB708A/LPB716A/LPB724A, is a standard 8-Port/16-Port/24-Port 10/100 PoE PSE Web Smart Switch that meets all IEEE 802.3u/x Ethernet specifications. The switch includes 8-, 16-, or 24-Port 10/100Mbps TP ports. LPB724A also features two combo UTP/SFP Gigibit ports. Manage the switch through an Ethernet port using Web-based management. The switch also features QoS (Quality of Service), Spanning Tree, VLAN, Port Trunking, and IGMP Snooping capability via the intelligent software. It is suitable for smalland medium-sized office applications.

This PSE switch also complies with IEEE 802.3af. Its advanced autosensing algorithm enables power devices (PD) discovery, classification, current limit, and other necessary functions. Safety features include short-circuit protection and power-out auto-detection to PD.

2.2 Features

Power-over-Ethernet: Provides built-in 802.3af Power over Ethernet for network sites that need to run power over the network cables. Each of the 10/100BASE-TX Ethernet ports on this switch provides up to 15.4 watts power for connected wireless access points, IP phones and other PoE-supported devices, enabling them to be deployed at difficult places such as on high walls and ceilings, where AC power outlets are not readily available.

QoS: Supports Quality of Service by the IEEE 802.1P standard. There are four priority queues enabling users to run bandwidth-sensitive applications such as streaming multimedia and VoIP in network.

Spanning Tree: Supports IEEE 802.1D, IEEE 802.1w (RSTP: Rapid Spanning Tree Protocol) standards to prevent network loops that could cause a broadcast storm.

VLAN: Supports Port-based VLAN and IEEE802.1Q Tag VLAN. Also supports 256 active VLANs and VLAN ID 1– 4094.

Port Trunking: Supports static port trunking and port trunking with IEEE 802.3ad LACP.

IGMP Snooping: Establishes the multicast groups to forward the multicast packet to the member ports, and avoids wasting the bandwidth while IP multicast packets are running over the network.

Security: Support MAC Address and TCP/UDP filtering to prevent unknown users or un-authorized actions connected to network.

3. Installation

3.1 Hardware and Cable Installation

CAUTION: Wear a grounding device to avoid damage from electrostatic discharge. Be sure that the power switch is OFF before you connect the power cord to the power source.

3.1.1 TP Port and Cable Installation

1.The switch’s TP port supports MDI/MDI-X auto-crossover, so you can use 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) and cross-over (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 3, 6, 1, 2). Simply plug in the cable.

2.Connect one end of a CAT5 grade RJ-45 TP cable or above to a TP port on the switch and connect the other end to a network-aware device such as a workstation or a server.

3.Repeat the above steps, as needed, for each RJ-45 port that you want to connect to a 10/100 TP device.

The switch is now ready to operate.

3.1.2 Installing an Optional SFP Transceiver Module

NOTE: If you do not plan to install SFP fiber transceivers in the LPB724A switch’s ports 25–26, skip this section.

Slide the fiber transceiver module into one of the two open module slots in the switch as shown in Figure 3-1. Connecting the SFP Module to the Chassis

The optional SFP modules are hot-swappable, so you can plug or unplug them before or after powering on the switch. Verify that the SFP module is the right model and conforms to the chassis.

Slide the module into the slot. Make sure that the module is properly seated against the slot socket/connector. Connect the fiber optic network cable to the connector(s) on the module.

If you want to install a second module in the switch, repeat steps 1–3.

SFP transceiver module

Chapter 3: Installation

3.1.3 Power On

The switch supports a 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 is plugged into the switch or not when powering on. After the power is on, all LED indicators will light immediately and then all go off except the power LED, which stays on.

3.2 Installing Switch 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 switch. Wear a grounding device for electrostatic discharge.

1.Using two screws (included), attach the rackmount ears to the switch’s left and right sides. See Figure 3-2.

2.Line up the mounting holes on the switch assembly (the switch with rackmount ears installed) with the mounting holes on a 19" wiring closet rack. Install two screws (included) to hold the switch in place in the rack.

Figure 3-2. Install the switch chassis in a 19"rack.

3.3 Cabling Requirements

To ensure a successful installation and maintain proper network performance, use the required cable types. Cables with lesser specification will cause the LAN to work poorly.

For a Fast Ethernet TP network connection, the cable grade must be CAT5 or CAT5e that‘s up to 328 feet (100 meters) long.

8-/16-/24-Port 10/100 PoE PSE Web Smart Switch

3.4 Switch Cascading in Topology

Theoretically, the switch partitions the collision domain for each port in switch cascading so that you may uplink an unlimited number of switches. In practice, the network extension (cascading levels and overall diameter) must comply with the IEEE 802.3/802.3u and other 802.1 series protocol specifications, which limit the timing requirement from physical signals defined by the Media Access Control (MAC) and PHY802.3 series specification, and the timer from some OSI layer 2 protocols such as 802.1d, 802.1q, and LACP.

The TP cables, and devices’ bit-time (round-trip) delay are as described in Table 3-1.

100Base-TX TP

Round trip Delay: 512

Cat. 5 TP Wire: 1.12/m

TP to fiber Converter: 56

Bit Time unit: 0.01 s (1sec./100 Megabits)

Table 3-1. Cable’s bit-time (round-trip) delay.

Sum up all elements’ bit-time delay and the overall bit-time delay. They must be within Round Trip Delay (bit times) requirements in a half-duplex network segment (collision domain). For full-duplex operation, this doesn’t apply.

3.5 Typical Network Topology in Deployment

A hierarchical network with minimum switch levels may reduce the timing delay between server and client station. This will minimize the number of switches in any one path, lower the possibility of network loops, and 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. We recommend connecting the Server/Host to the Level 1 switch if no VLAN or other special requirements are used.

Case1: All switch ports are in the same local area network. Every port can access each other (See Figure 3-3).

Figure 3-3. No VLAN Configuration Diagram.

If VLAN is enabled and configured, each node in the network that can communicate each other directly is bound 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 differences are.
