PRODUCT INFORMATION

1. What is the Linksys LGS124P Business PoE+ Gigabit Unmanaged Switch? 

The Linksys LGS124P Business PoE+ Gigabit Unmanaged Switch is an unmanaged switch that offers a quick and easy solution to extend your office network with a plug-and-play installation.  It is also useful in transferring data across a local network at Gigabit speeds. 
 

2. What is PoE? 

Power over Ethernet (PoE) is a technology that enables an ethernet network cable to deliver both data and power.
 
3. What kind of devices can be connected to the switch? 

You can connect the following devices to your Linksys LGS124P switch:
  • Computers
  • Routers
  • Switches
  • Network printers
  • Other network devices   
4. What is the advantage of having a switch when it comes to data transfer? 

The switch acts as a repeater which regenerates data signals as they pass through it.  This feature acts as a safeguard to deter data loss and ensure that transmissions arrive securely at their destinations.  Moreover, a switch is capable of intelligent filtering of data based on source and destination as compared to the repeater which can only regenerate the signal without checking its recipients.
 
5. What is the maximum PoE power budget for each PoE switch?
 
The Linksys LGS124P has 120 Watts dedicated PoE power budget for the entire switch.
 
6. What are the protocols supported by the Linksys LGS124P?

The Linksys LGS124P switch is compliant with IEEE 802.3, 802.3u, 802.3x, 802.3ab, and 802.3az standards.
 
7. Can I wall-mount my switch?

No, the Linksys LGS124P can only be rack mounted.
 
8. Can I use a switch to share internet connection to all computers in the network? 

No.  The switch is not capable of sharing internet connection across the network.  However, what it does is it allows more computers to be connected to a local network. 
 
NOTE:  Only routers or modems with DHCP capabilities can allow sharing of internet connection between computers.  

 
9. Which ports on my PoE switch can I plug in a PoE device? 

You can plug the PoE device to Ports 1-6 and Ports 13-18 of the switch.
 
10. How is port PoE prioritization done?

The switch has a feature called PoE prioritization where power is provided based on port priority for PoE devices connected to the PoE ports.  This follows the criteria below:
 
a.  Port 1 has higher priority.
b.  The higher the port number, the lower the priority.
c.  Rebooting the switch reprioritizes PoE per port. 

NOTE:  This is only applicable for those ports that have a PoE device connected to it. 

An example is if all 11 PoE devices have maxed out the power budget on the switch.  When a twelfth PoE device connects, since it exceeds the power budget, the connection is declined and Port 18 will not provide power to a PoE device.  However unplugging Port 1 will then provide power to Port 18 for the PoE device connected to it.

QUICK TIP:  If the device is a non-PoE device this behavior does not apply.
 
If the PoE device is reconnected back to Port 1, Port 1 remains OFF.  In order to restore power to Port 1 for the PoE device either unplug PoE device from Port 18 or reboot the switch.  Rebooting the switch prioritizes PoE for each port all over again.

 
11. What is the warranty period for the Linksys LGS124P?
 
The Linksys LGS124P V1 has a limited lifetime warranty while the Linksys LGS124P V2 has a 5-year warranty.

12. What are the supported PoE standards? 

The switch only supports IEEE 802.3af and IEEE 802.3at.  Any PoE devices not supporting these standards will not be powered ON by the switch.

13. How much power does the Linksys LGS124P consume?

The total power consumption with POE is 155.86 W at 110 V AC (153.82 W at 220 V).

TROUBLESHOOTING

1. What should I do when my computer cannot connect to the internet while connected to the switch?

Follow the steps provided below to resolve this issue:
 
Step 1:
Verify if the indicator lights are properly lit on the switch.  

System Indicator Light – Blue
Link / Act / GB – Green-Orange
PoE Max - Orange
PoE - Green


Step 2:
Power down everything and power ON the switch first.  Next, power ON the computer. 

 
NOTE:  Only routers or modems with DHCP capabilities can allow sharing of internet connection between computers.  

2. What should I do if my switch experiences excessive data collisions?

Verify if your network cabling is securely crimped and installed properly.
 
3. My PoE device is not powering ON, what should I do? 

If your PoE device is not powering ON, do the following:
  • Verify with the vendor if it supports IEEE 802.3af and IEEE 802.3at.  The switch only supports these PoE standards. 
  • Make sure your PoE device is connected to a PoE port. 
  • If you have several PoE devices already connected to the switch, you may have exceeded the power budget of the switch.
