Chapter 1 Network Interface Card (NIC)
Network Indicator
The NET LED displays the status of the network link. When the NET LED is
on, link integrity is confirmed. The NET LED flashes off for 1/3 second when a
data packet is being transferred. When the NET LED is off, the network
connection has been severed.
Dipswitches
On the back of the interface, you will find a small window where you can
access two dipswitches labeled 1 and 2 (see Figure 4). The functions of the
dipswitches are explained in Table 3.

OFF OFF Normal operation. With both dipswitches in the OFF
position, the NIC boots up using the settings in flash
memory rather than the default settings.
ON OFF Factory default settings. With the dipswitches in this
configuration, the NIC boots up and erases all settings
stored in flash memory except the Ethernet address
and key value.
OFF ON Default IP. With the dipswitches in this configuration,
the NIC boots up with factory default settings.
However, the stored settings in flash memory are
intact. Setting dipswitch 2 to ON does not clear any
settings stored in flash memory; instead, it boots the
unit with the IP settings in flash memory temporarily
ignored.
ON ON Reserved. This dipswitch setting is not for customer
use.
