D-Link xStack DXS-3350SR Installation & User Manual - Front-Panel Components

DXS-3350SR Gigabit Layer 3 Switch 

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.

Comprehensive LED indicators display the status of the Switch and the network. 

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. 

Figure 1- 3. LED Indicators 

LED                       Description 

Power 

This LED will light green after the Switch is powered on to indicate the ready state of the 

device. The indicator is dark when the Switch is powered off. 

Master 

This LED will light solid green when the Switch is configured to be a master Switch of a Switch 

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. 

Console 

This LED should blink during the Power-On Self Test (POST). When the POST is finished 

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. 

RPS 

This LED will be lit solid amber when the internal power has failed and the RPS has taken over 

the power supply to the Switch. Otherwise, it will remain dark. 

Port LEDs 

One row of LEDs for each port is located above the ports on the front panel. The first LED is 

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. 

Stacking Ports 

(SIO) 

There are two LEDs in the front of the Switch marked SIO, and they relate to the two 10-

gigabit stacking ports at the rear of the Switch. These LEDs are marked 1 and 2 and will light 

solid green to denote a valid link on the port, while a blinking light indicates packet activity on 

the port. 

Stack ID 

These two seven segment LEDs display the current Switch stack order of the Switch while in 

use. Possible numbers to be displayed range from 1-12.
