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 Installing an Optional SFP Transceiver Module
NOTE: If you do not plan to install SFP fiber transceivers in the switch’s ports 7–8, 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.
Figure 3-1. Installing the optional SFP fiber transceiver module.
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.
1.
Verify that the SFP module is the right model and conforms to the chassis.
2.
Slide the module into the slot. Make sure that the module is properly seated against the slot socket/connector.
3.
Connect the fiber optic network cable to the connector(s) on the module.
If you want to install a second module in the LPB4008A switch or second, third, and fourth module in the LPB4024A switch, repeat
steps 1–3.
3.1.2
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; 1, 2, 3, 4, 5, 6, 7, 8 to 1, 2, 3, 4, 5, 6, 7, 8 in Gigabit TP) and cross-over (Cable
pin-outs for RJ-45 jack 1, 2, 3, 6 to 3, 6, 1, 2).
2.
Use CAT5 RJ-45 TP cable to connect to one of the switch’s TP port and a network-aware device such as a workstation or a server.
3.
Repeat the above steps, as needed, for each RJ-45 port you want to connect to a Gigabit 10/100/1000 TP device.
4.
The switch is now ready to operate.
