HARDWARE INFORMATION
 
1.  What is the Linksys LGS318P?
 
The Linksys 18-Port Smart PoE Gigabit Switch, LGS318P offers a quick and easy solution to extend your office network and connect the wired devices together at up to Gigabit speeds.  Through its web-based setup page, the Smart Switch also provides simple configuration and management to users.  For more information about this, click here.
 
2.  Is running a setup CD needed for this device to work?
 
No.  You don't have to configure any since the Smart Gigabit Switch is a plug-and-play device.  Setting up the device though, requires you to access its web-based setup page.  For more information, click here.
 
3.  Can I wall or rack-mount my switch?
 
Yes, the Linksys LGS318P can be wall or rack-mounted.  For instructions on how to rack mount your switch, click here.

4.  What is the Linksys Smart Gigabit Switch, LGS318P’s IP address?
 
The switch is acting as a DHCP client by default.  If there is no DHCP server on your network, the default IP address of the switch is 192.168.1.251/255.255.255.0.
 
5.  What is PoE?
 
Power over Ethernet (PoE) is a technology that enables an Ethernet network cable to deliver both data and power.
 
6.  What kind of devices can be connected to the switch?
 
The device’s PoE+ support allows networking device such as hubs, IP phone, IP cameras, computers, routers, switches, and network printers to be connected to it.
 
7.  What is the advantage of having a switch when it comes to data transfer?
 
The switch's Gigabit speed ports provide high bandwidth capabilities.  It also acts as a repeater which regenerates data signals as they pass through the device.  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.
 
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 but it allows more computers to be connected to a local network. 
 
9. Does the LGS318P support QoS?
 
The Smart Gigabit Switch does not support QoS advance mode, only QoS basic mode.
 
10. Does the LGS318P support Port Mirroring?
 
Yes, up to four (4) sources to one (1) target.
 
11. What are the package contents of the Linksys LGS318P?
 
The Linksys LGS318P package contains the following items:
  • Linksys SMB Smart Switch
  • Quick Start Guide
  • Power cord and adapter
  • CD with documentation
  • Rack mount kit or wall mount kit
12. What is the PoE power budget for the Linksys LGS318P?
 
The PoE power budget of Linksys LGS318P is 125 W, up to 16 PoE+ ports.
 
13. What are the supported PoE standards?
 
The switch supports both IEEE 802.3af and IEEE 802.3at (PoE+).
 
14. Does the LGS318P have fan support?
 
Yes, the Linksys LGS318P has one (1) fan.
 
NOTE:  Fan failure is indicated by System LED blinking amber.
 
LEDs
 
1.  What do the LEDs in the Smart Gigabit Switch, LGS318P mean?
 
System LED - Indicates the device’s status and activities.
  • OFF - System is powered OFF.
  • Solid Blue - System is ON and operative.
  • Blinking Blue:
? Booting/System Self-Test
? Device is using the factory default IP address of 192.168.1.251
  • Blinking Yellow - Failure detect (e.g. Fan)  
PoE MAX - Indicates the PoE power budget status of the switch (for PoE models only).
  • OFF - Total power feeding does not reach 85% of total power budget.
  • Solid Amber - Total power feeding is reaching over 85% of total power budget. 
Combo port LED’s
  • Left - Link/Activity
? OFF - No link detected
? Solid - Link is detected/established
? Blinking - Transmitting/receiving Data 
  • Right - Speed
? OFF - 10/100 Base-TX link detected or link down
? Solid - 1000 M Link detected 

RJ-45 Port LEDs
  • Left - Link/Activity
? OFF - No link detected
? Solid - Link is detected/established
? Blinking - Transmitting/receiving Data 

NOTE:  For more information about the Smart Gigabit Switch LEDs, click here.

2.  Why do the System LED keep blinking?
 
The System LED flashes when the device is acquiring an IP address and when currently using the factory default IP address 192.168.1.251.  The system status LED changes to solid blue when a new unique IP address is received from the DHCP server or a static IP address has been set.
 
3.  When will the PoE MAX LED turn ON?
 
The PoE MAX LED turns ON when the switch is providing more than 85% of its total PoE budget.  The LED gives the user a warning that only 15% of the total PoE budget is available.

TROUBLESHOOTING
 
1.  How do I upgrade the Smart Switch’s firmware?
 
The Linksys Smart Switches’ firmware upgrade can be done through HTTP/HTTPs mode or TFTP mode in their web-based setup page.  For instructions, click here.

2.  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:
  • Verify if LEDs are properly lit on the switch. 
SYSTEM - Blue
LINK/ACT - Green
PoE MAX - Amber
  • Power down everything and power ON the switch first.  Next, power ON the computer.
3.  What should I do to ensure that I can re-access my switch if I would change the VLAN management?
 
To access your device, the computer’s access port has to be a member of management VLAN.  Before changing the management VLAN, ensure that the access port of your computer must also be a member of the new Management VLAN.  Otherwise, you may not be able to re-access your switch and you will have to reset the system to default.
 
4.  What can I do if I forgot my login password?
 
The switch can be set to factory default by pressing the reset button for over 10 seconds.  The username/password will revert to admin/admin.
 
5.  Can I configure my switch through its web-based setup page?
 
Yes, the Smart Switches can be configured using their web-based setup page.  To know how, click here.
 
6.  Can I back up the configuration file and save configuration changes on my switch?
 
Yes.  You can perform these on the switch’s web-based setup page.
 
7. How do I configure the switch’s QoS?
 
The QoS configuration options are as follows:
  • CoS settings
  • Queue settings
  • Bandwidth
  • Basic Mode QoS
You can configure these options through web-based setup page.  To know more, click here.
 
8.  How do I restart the Smart Switch?
 
You can restart the switch by pressing the reset button or perform a restart through web-based setup page.  For more information in restarting the switch, click here.
 
9.  How can I reset my Switches to factory default?
 
The switch can be set to factory defaults by pressing the reset button for over 10 seconds or through its web-based setup page.
