2.6.6 Connecting to an Ethernet Network at the DESQA
Module
Your system may also have a DESQA Ethernet controller. Two types
of DESQA modules are available. They are the same except one has
an external Ethernet connector switch. Both modules can accommodate
either ThinWire or standard Ethernet cabling. Figure 2–31 shows the
location of the external Ethernet connector switch.
If your module does not have the connector switch, you can still connect
to the ThinWire Ethernet. To connect to the standard Ethernet port, you
must call a Digital service representative.
CAUTION
Turn off the system before you select a connector to
avoid disrupting the network.
With the Ethernet connector switch you can select either a ThinWire or
a standard Ethernet connection. When the Ethernet connector switch is
set to the out position, the ThinWire connector is selected. When the
switch is set to the in position, the standard connector is selected. An
indicator next to the connector lights when the system is powered on to
indicate which port is selected.
2.6.6.1 Making a ThinWire Network Connection at the DESQA Module
To Make a ThinWire network connection at the DESQA module perform
the following:
1. Find the DESQA module.
2. Make sure the Ethernet connector switch is in the out position (see
Figure 2–31).
3. Push in and turn the T-connector plug on the DESQA module coun-
terclockwise until it unlocks. Figure 2–32 shows a ThinWire cable,
T-connector, and terminator.
