Network Connections
Your system supports various Ethernet network options. You can connect to
ThinWire, AUI, or 10Base-T Ethernet networks as shown in Figure 2-5. With the
correct option, you can also connect to FDDI and token ring networks.
Setting Network Configuration
Any new network device is initially set to AUI mode, which is preserved in memory
until the network type is changed using the following command:
set ewx0_mode mode_name
In this command, x identifies the controller, and
mode_name
is the mode to be
selected. To determine the controller ID, use the
show config
command (see
Example 6-1) or the
show device
command (see Example 6-2). Refer to the
following configuration command examples to set the network configuration for the
network option card:
>>> set ewa0_mode twisted-pair
(10BASE-T/twisted-pair network)
>>> set ewa0_mode full
(full duplex, twisted-pair network)
>>> set ewa0_mode aui
(AUI/standard network)
>>> set ewa0_mode bnc
(ThinWire network)
Mode names can be abbreviated; the system prompts you with correct names if you
enter an invalid name. To verify the network setting, use the
show
command:
>>> show ew*
CAUTION: Modes for all network devices should be
reassigned whenever a network device is moved, installed, or
removed because associations between devices and the device
names and modes they are set to may be altered.
Power Supply
The system has a single power supply that provides all the power your system needs.
For added reliability, you can add a second power supply, which provides redundant
power for a fully loaded system. Refer to "Installing and Removing Components" for
instructions on adding a second power supply to your system.
