LED Indicators
The LED indicators of the Switch include Power, 100M, Link/Act
(Link/Activity), and Slot. The LED indicators are used to facilitate monitoring
and troubleshooting of the Switch. The following shows the LED indicators for
the Switch along with an explanation of each indicator.
◆
Power This indicator operates when the Switch is turned on. If this indicator
is not lit, check the AC power connector to ensure proper insertion of the
power cord.
◆
100M The LED indicator lights green when a 100 Mbps device is connected
to a respective port. If a 10 Mbps device is connected to a respective port,
the LED indicator is OFF.
◆
Link/Act These LED indicators are lighted 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.
◆
Slot This LED indicator is lighted green when there is a secure connection
(or link) to an optional two-port 100BASE-FX (SC type) module is installed
in the front panel. Each port has its own LED, designated as I and II. See
