1000Base-T Copper Gigabit Module; Led Indicators - D-Link DES-3225G Series User Manual

1000BASE-T Copper Gigabit Module

♦ One-port, rear-panel module.
♦ Connects to 1000BASE-T devices at 1000M/full duplex, 100M/full duplex, 100M/half duplex, and Auto.
♦ Supports Category 5+ or higher cable connections of up to 100 meters.

LED Indicators

The LED indicators of the Switch include Power, Console, Slot2, Giga, Speed, and Link/Act. The following
shows the LED indicators for the Switch along with an explanation of each indicator.
♦ Power This indicator on the front panel should be colored amber during the Power-On Self Test
(POST). It will light green approximately 2 seconds after the switch is powered on to indicate the ready
state of the device. The LED will blink green while downloading new software for the switch, or if the
system's configuration has changed and will light yellow when an error occurs.
♦ Console This indicator is lit green 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.
♦ Slot 2 This indicator is lit green when a Gigabit Ethernet slide-in module is present in the rear panel
of the Switch.
♦ Giga This indicator is lit green when a link is established. It blinks green when the Gigabit port is
active.
♦ 100M These indicators are illuminated green when a 100 Mbps device is connected to any of the 24
ports or uplink port. If a 10 Mbps device is connected to any of the 24 ports or uplink port, these LEDs
remain dark.
♦ Link/Act These indicators are lit when there is a secure connection (or link) to a device at any of the
ports. The LEDs blink whenever there is reception or transmission (i.e. Activity--Act) of data occurring
at a port.
