Front-Panel Components; Led Indicators - D-Link dxs-3350sr Installation & User Manual

Front-Panel Components

The front panel of the Switch consists of LED indicators for Power, Master, Console, RPS, SIO (stacking) and for Link/Act
for each port on the Switch. The front panel also includes a seven-segment LED indicating the Stack ID number, as well as
4 SFP ports, 48 1000BASE-T gigabit Ethernet ports.

LED Indicators

The Switch supports LED indicators for Power, Master, Console, RPS, SIO (stacking indicators) and Port LEDs. The
following shows the LED indicators for the Switch along with an explanation of each indicator.
LED Description
This LED will light green after the Switch is powered on to indicate the ready state of the
Power
device. The indicator is dark when the Switch is powered off.
This LED will light solid green when the Switch is configured to be a master Switch of a Switch
Master
stack in a ring topology or when it is in use as a stand-alone Switch. This LED will remain dark
if the Switch is not configured to be a master Switch of a Switch stack.
This LED should blink during the Power-On Self Test (POST). When the POST is finished
Console
successfully, the LED goes dark. This indicator will light solid green when the Switch is being
logged into via out-of-band/local console management through the RS-232 console port in the
front of the Switch using a straight-through serial cable.
This LED will light solid amber if the Power-On-Self-Test has failed.
This LED will be lit solid amber when the internal power has failed and the RPS has taken over
RPS
the power supply to the Switch. Otherwise, it will remain dark.
One row of LEDs for each port is located above the ports on the front panel. The first LED is
Port LEDs
for the top port and the second one is for the bottom ports. A solid light denotes a valid link on
the port while a blinking light indicates packet activity on the port. These LEDs will remain dark
if there is no link/activity on the port.
There are two LEDs in the front of the Switch marked SIO, and they relate to the two 10-
Stacking Ports
gigabit stacking ports at the rear of the Switch. These LEDs are marked 1 and 2 and will light
(SIO)
solid green to denote a valid link on the port, while a blinking light indicates packet activity on
the port.
These two seven segment LEDs display the current Switch stack order of the Switch while in
Stack ID
use. Possible numbers to be displayed range from 1-12.
