3.2.5 LAN Port LEDs
A shielded Ethernet cable must be used to connect the RJ-45 Ethernet port
to a hub on a network after you assign a permanent IP to the A16F-R/S2221.
This enables you to manage your subsystem via the web. Two (2) LEDs
located on the Ethernet port indicate the Ethernet connection status. See
Figure 3-4
for the locations of the two (2) LED indicators. Refer to
Table
