7.6 Testing the RLB Module

During Bench Configuration, you can quickly test your MS RLB Modules to verify that they are working properly.

THINNET

By default, the BNC connector on the RLB Module is active. ThinNet Ethernet can connect directly to the back of the RLB Module. No external transceiver is necessary.

The first step is to connect the Local Multiserver to the local Ethernet LAN. See Figure 7-5.

•Attach a BNC Coaxial T Connector (FC115) to the BNC connector on the RLB Module.

•Attach the Ethernet backbone directly to the T Connector.

•If necessary, use a BNC Resistor Terminator Cap (FC135) on the other end of the

T Connector.

Using the Remote Multiserver’s RLB Module and another Ethernet device, create a two-node Ethernet LAN. In the example shown in

Figure 7-5, a PC with an Ethernet card is used as the second node.

•Attach a BNC Coaxial T Connector (FC115) to the BNC connector on the RLB Module. Terminate one end with a BNC Resistor Terminator Cap (FC135).

•Attach a BNC Coaxial T Connector (FC115) to the Ethernet card on the PC. Terminate one end with a BNC Resistor Terminator Cap (FC135).

•Connect the two units with ThinNet Coaxial Cable (LCN300).

After all cable are correctly attached, power up your Multiservers. From the device connected to the Remote Multiserver, you should be able to access any device on the LAN that is connected to the Local Multiserver. In the example shown in Figure 7-5, the PC should be able to access the file server (assuming that they are using the same Ethernet protocol).

THICKNET, 10BASE-T, AND FIBER

If you are using ThickNet, 10BASE-T, or fiberoptic Ethernet, you will need to move the jumper on the RLB from W21 to W20 to enable the AUI port and disable the BNC connector. Refer to the MS RLB Module User’s Manual for more information.

After the AUI port is enabled, connect the Local Multiserver to the local Ethernet LAN. The RLB Module connects to the Ethernet backbone just like any other node on the LAN.

•ThickNet. Attach a Thick Ethernet Transceiver (LE003A) to the Ethernet backbone. You will need to run PVC Transceiver Cable (LCN200A) between the transceiver and the RLB Module’s AUI port.

•10BASE-T and Fiberoptic. Attach an appropriate transceiver to the Ethernet backbone: 10BASE-T Transceiver (LE2010A) for 10BASE-T or Mini-FOIRL (LE027A) for fiberoptic. You can either attach the transceiver directly to the RLB module’s AUI port or use PVC Transceiver Cable (LCN200A) in between the transceiver and the AUI port.

Use the Remote Multiserver’s RLB Module and another Ethernet device to create a two-node Ethernet LAN. The Local Multiserver and Remote Multiserver can be connected to different types of Ethernet cabling—the RLB Modules will pass any standard Ethernet packet. A PC with an Ethernet card can be connected to the Remote Multiserver using ThinNet (see Figure 7-5).

After all cables are correctly attached, power up your Multiservers. From the device connected to the Remote Multiserver, you should be able to access any device on the LAN that is connected to the Local Multiserver (assuming that both devices are using the same Ethernet protocol).

FURTHER CONFIGURATION

After the quick test has verified that the MS RLB Modules are working correctly, consult the MS RLB Module User’s Manual and continue to configure the RLB Modules to your requirements. If your remote offices will not be using ThinNet, be sure to change the jumper to enable the AUI port on the Remote Multiserver’s RLB Module.
