Rear Panel Description

The AC power connector is a standard three-pronged connector that supports the power cord. Plug the female connector of
the provided power cord into this socket, and plug the male side of the cord into a power outlet. The Switch automatically
adjusts its power setting to any supply voltage in the range from 100 ~ 240 VAC at 50 ~ 60 Hz.
The rear panel also includes an outlet for an optional external power supply. When a power failure occurs, the optional
external RPS will immediately and automatically assume the power supply for the Switch.
The rear panel of the DWS-3024/DWS-3024L contains an AC power connector, a system fan vent, and a redundant power
supply connector.

Description
You can change the mode of the LEDs over each port to display the information about the link,
activity, and speed of a port or whether 802.3af Power Over Ethernet (PoE) is supporting
devices attached to the port.
To change the LED mode from Link/Act/Speed to PoE and vice versa, press the LED Mode
Select Button.
One row of LEDs for each port is located above the ports on the front panel. The indicator
above the left side of a port corresponds to the port below the indicator in the upper row of
ports. The indicator above the right side of a port corresponds to the port below the indicator
in the lower row of ports. The port LEDs show information about link, activity, and speed on
the port or Power over Ethernet usage on the port, depending on the LED mode you select.
For Link/Act/Speed Mode:
• Solid Green—Indicates a valid 1000Mbps link on the port, while a blinking green light
indicates activity on the port (at 1000Mbps).
• Solid Amber—Indicates a valid 10 or 100Mbps link on the port.
• Blinking Amber—Indicates activity on the port (at 100Mbps).
• Off—No link/activity on the port.
For PoE Mode:
• Solid Green—Power feeding (802.3af-compliant PD was detected).
• Blinking Amber—PoE port ERROR (non-standard PD connected, Under load state according
to 802.3af (current is below I min), Overload state according to 802.3af (current is above I
cut), hardware problems preventing port operation, power budget exceeded, short condition
was detected at a port delivering power, temperature overload at the port, succession of
Underload and Overload states caused port shutdown (may be caused by a PD's DC/DC
fault)...etc.)
• Off—No power feeding (no PD detected, or no connection)
(DWS-3026 only) A steady green light denotes a valid link on the port while a blinking green
light indicates activity on the port. These LEDs remain dark if there is no link/activity on the
port.
The LED indicators for the Combo ports are located above the ports and numbered 1 – 4 for
Combo 1, Combo 2, Combo 3, and Combo 4 ports. A steady green light indicates a valid link
on the port while a blinking green light indicates activity on the port. These LEDs remain dark
if there is no link/activity on the port.
