2.4 Optional SFP Fiber Transceiver Modules

Ports 7–8 on the LGB2008A-R2 include two types of media: twisted-pair (TP) and optional small form factor pluggable (SFP) fiber (LC, BiDi LC, etc.) modules. The twisted-pair ports are the switch’s two rightmost RJ-45 twisted-pair connectors (ports 7–8). For the fiber option, 1000-Mbps fiber transceiver modules slide into the switch’s two fiber module slots (located to the right of the twisted-pair connectors on the switch’s front panel). The fiber transceiver modules are used for high-speed connection expansion. The two fiber ports auto detect 10/100/1000-Mbps TP or 1000-Mbps SFP fiber.

Five 1000-Mbps transceiver modules are available. These modules are described below and shown in Figures 2-2 and 2-3.

3.1 Installation Instructions

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 INSTALLING THE OPTIONAL MODULES

NOTE

If you are not installing modules in Ports 7–8, skip this section.

1. Verify that the SFP module is the right model and conforms to the chassis.

2. Slide the module into the slot as shown in Figure 3-1. Make sure that the module is properly seated against the slot socket/connector.

3. Install the fiber optic cable (see Section 3.1.2) for network connection.

4. Repeat the above steps for the second module and slot, if needed.

5. Power on the switch.

CHAPTER 3: Installation

3.1.2 C

The switch’s twisted-pair ports support MDI/MDI-X auto-crossover, so you can use either straight-through or cross-pinned UTP cable.

Use Category 5 or 5e grade RJ-45 twisted-pair cable to connect up to 24 network devices (such as workstations or servers) to the switch’s UTP ports.

Use 1310-µm single-mode, or 1550-µm single-mode fiber optic cable to connect the fiber module to the

network.

3.1.3 P

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 doesn’t matter whether any devices are plugged into the switch or not when you power on the switch (including modules). Once the power is on, all LEDs (except for the Power LED) will light immediately and then turn off. The Power LED will remain on.

After resetting, the boot loader will load the firmware into memory. This takes approximately 30 seconds. After that, all LEDs will flash once and the switch will automatically run a self-test.

3.1.4 I

Attach the four included rubber feet to the switch’s bottom. Then place the switch on a desktop.

3.2.3 S

WITCH CASCADING

Theoretically, the switch partitions the collision domain for each port in switch cascading so that you may up-link an unlimited number of switches. In practice, the network extension (cascading levels and overall diameter) must comply with the IEEE 802.3/802.3u/802.3z 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 timer from some OSI layer 2 protocols such as 802.1d, 802.1q, and LACP.

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

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

1000BASE-X TP, Fiber 100BASE-TX TP 100BASE-FX Fiber

Round-Trip Delay: 4096 Round-Trip Delay: 512

Cat. 5 TP Wire: 11.12/m Fiber Cable: 10.10/m Bit Time Unit: 1 ns (1 sec./1000 Mega bit)

The sum of all elements’ bit-time delay and the overall bit-time delay of wires/devices must be within the bit-time (round-trip) delay in a half-duplex network segment (collision domain). For full-duplex operation, this will not apply. Use the TP-Fiber module to extend the TP node distance over fiber optic cable and to provide the long-haul connection.

Cat. 5 TP Wire: 1.12/m Fiber Cable: 1.0/m TP to Fiber Converter: 56 kbps Bit Time Unit: 0.01 ms (1 sec./100 Mega bit)

Typical Network Topology in Deployment

A hierarchical network with minimum switch levels may reduce the timing delay between the server and the client station. This approach will minimize the number of switches in any one path. It will also lower the network loop possibility and will improve network efficiency. If more than two switches are connected in the same network, select one switch as the Level 1 switch and connect all other switches to it at Level 2. We recommend that you connect a server/host to the Level 1 switch.

Example 1: Same LAN.

All switch ports are in the same local area network. Every port can access each other (see Figure 3-2).
