Function
On continuously or flashes when port is receiving or transmitting data. When traffic
on the network segment is heavy, the LED is on continuously; when traffic is light,
the LED flashes; when there is no traffic, the LED is off. The Network Activity LED on
the front panel also indicates traffic on the network segment.
On when a connection between the port and a workstation, hub, or repeater exists.
Flashes if the connection exists but polarity of the cable is reversed. The module
corrects automatically for polarity reversal.
Off when polarity is normal, on when polarity is reversed.
Figure 1-8 also shows a connector mounted directly on the board. This
connector mates with a connector on the motherboard.
For information on how to install the single-port RJ-45 module in the server
and cable it to a twisted-pair network, refer to Chapter 2, "Installation."
The power supply module is located on the left side of the server's back
panel. It includes a power switch, fuseholder, and power cord receptacle, as
shown in Figure 1-9. The switch is marked according to international I/O
convention. When the I side is pressed, the switch is on; when the O side is
pressed, the switch is off.
