PURE NETWORKING RS-232/422/485 TO TWISTED-PAIR DEVICE SERVER

4. Operation

Once the server is installed, its four front-panel LED indicators (Lnk/Act, Act, Sys,
and 100) and its rear-panel Pwr LED give you status at a glance. The first time you
use the server, you must configure it by following the instructions in 

Chapter 5

.

When the Pwr LED is on, the server is operating in normal power mode. When this
LED is off, the power is off or has failed.

The Lnk/Act LED lights when the switch’s respective port is connected to the
network. This LED blinks when the port is transmitting or receiving data on the
Ethernet network. The Link/Act LED is off when no link is connected.

The Act LED lights when the server is receiving data packets. When it’s off, the
server is transmitting or receiving RS-232/422/485 data packets.

The Sys LED blinks when the CPU is working. When this LED is continuously on
or off, the CPU is not working.

The 100 LED is on when the switch’s respective twisted-pair port is connected to a
Fast Ethernet network. This LED is off when the switch’s respective port is
connected to a 10-Mbps Ethernet port.
