Identifying External Components

After the system’s initial check and power is on, this LED indicator is
ON (green) when a secured connection is established at the port,
otherwise it is OFF.

Console. This LED indicator is lit when the switch is being managed
via out-of-band/ local console management through the RS-232
console port using a straight-through serial cable. When a secured
connection is established, this LED indicator is lit green. Otherwise, it
is OFF.

100 M. These LED indicators are illuminated (green) when a 100
Mbps device is connected to any of the 8 ports or uplink port. If a 10
Mbps device is connected to any of the 8 ports or uplink port, these
LED indicators are OFF.

Link/Act. These LED indicators are lighted up (green) when there is
a secure connection (or link) to a device at any of the ports. The LED
indicators blink (green) whenever there is reception or transmission
(i.e. Activity--Act) of data occurring at a port.

FDX/Col. This LED indicator is green when a respective port is in
full duplex (FDX) mode. Otherwise, it is OFF for half duplex (HDX)
operations. It blinks yellow when collisions are occurring on the
respective port.

System Load. Indicates the current traffic load on the Switch. The
system load bar provides a quick reference of the current traffic load
relative to the capacity. It is a measure of the number of packets
traversing within the device. Only valid packet and transmit packet
are counted. The first six LED indicators are green; the last two LED
indicators are yellow.
