7.6 Testing the RLB Module
During Bench Configuration, you can quickly test
your MS RLB Modules to verify that they are
working properly.
T HIN N ET
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).
T HICK N ET , 10BASE-T, AND F IBER
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).
F URTHER C ONFIGURATION
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.
