PRODUCT INFORMATION
Power over Ethernet (PoE) is a technology that enables an ethernet network cable to deliver both data and power. PoE+ is simply the upgrade for PoE and the more current standard for this technology.
You can connect the following devices to the Linksys LGS124P:
- Computers
- Routers
- Switches
- Network printers
- Other network devices
The switch acts as a repeater that regenerates the data signals as they pass through it. This feature acts as a safeguard to deter data loss and ensures that transmissions arrive securely at their destinations. Moreover, a switch is capable of intelligent filtering of data based on the source and destination as compared to a repeater which can only regenerate the signal without checking the recipients.
The Linksys LGS124P has a dedicated PoE+ power budget of 120W.
The Linksys LGS124P switch is compliant with IEEE 802.3, 802.3u, 802.3x, 802.3ab, 802.3az, 802.3af, and 802.3at standards.
No. The Linksys LGS124P can only be mounted on a rack.
No, the switch does not have this capability. Only routers or modems with DHCP capabilities can allow sharing of internet connection between computers. However, a switch can allow more computers to connect to a local network. For the computers to have internet access, the switch should be connected to a router or modem.
You can plug a PoE device into any one of the 12 PoE ports on the switch, which are Ports 1 to 6 and Ports 13 to 18. These ports have PoE+ support.
The switch has a feature called PoE prioritization where power is provided based on port priority for the PoE devices that are 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 the PoE device per port
An example of this is if there are PoE devices in Ports 1 to 3 that have maxed out the power budget on the switch, if a PoE device is connected to Port 4, the connection will be declined and the switch will not be able to provide power to the PoE device. You can then unplug the device in Port 1 to provide power to Port 4 for the PoE device connected to it.
If the PoE device is reconnected back to Port 1, Port 1 will remain turned OFF. To restore power to Port 1, you can either unplug the PoE device from Port 4 or reboot the switch. Rebooting the switch reprioritizes the PoE devices on each of the ports.
This feature is only applicable to ports that have PoE devices connected to them. If a connected device is non-PoE, this behavior will not apply.
The Linksys LGS124P v1 and v2 have a 5-year warranty.
The switch only supports IEEE 802.3af (PoE) and IEEE 802.3at (PoE+). Any PoE devices not supporting these standards can't be powered up by the switch.
The total power consumption with PoE is 155.86W at 110V AC (153.82W at 220V).
Yes, the switch has a QoS feature. However, Linksys LGS124P is not a manageable switch; therefore, the QoS setting is predefined and can't be configured or customized.
TROUBLESHOOTING
Follow the steps provided below to resolve this issue:
1. Verify if the switch and the computer are connected properly and the indicator lights on the switch are properly lit as outlined below:
- System - Solid blue when the switch is powered up
- Link/Act/GB - Solid green or orange depending on the speed link-up
- PoE - Solid green if the power is up for the PoE device
- PoE Max - Solid orange if nearing 85% of the maximum power budget
2. Power down everything then power up the switch then do the same to the computer.
Only routers or modems with DHCP capabilities can allow sharing of internet connection between computers. For a computer on a switch to have internet access, the switch should be connected to a router or modem.
When this happens, make sure that the network cabling is crimped securely and installed properly.
If your PoE device is not powering up, you can 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.
- Check if the power budget has been maxed out. If there are several PoE devices already connected to the switch, they may have exceeded the power budget of the switch.
