Selecting a site for the switch
You can install an AT-x220-28GS switch on a table or desktop, in a
standard 19-inch equipment rack, or on a wall.
Observe the following requirements when choosing a site for your switch:
If you are installing the switch on a table, verify that the table is
level and secure.
If you plan to install the switch in an equipment rack, verify that the
rack is safely secured and will not tip over. Devices in a rack should
be installed starting at the bottom, with the heavier devices near
the bottom of the rack.
If you are installing the switch on a wall, ensure that the wall is
sturdy enough to hold the switch’s weight. You may need to
position the switch so that it can be screwed into the wall’s framing
timber or an equivalent structural element.
The power outlet for the switch should be located near the unit and
should be easily accessible.
The site should provide for easy access to the ports on the front of
the switch. This will make it easier for you to connect and
disconnect cables, as well as view the switch’s LEDs.
The site should allow for adequate air flow around the unit and
through the cooling vents on the front and rear panels. (The
ventilation direction is from front to back.)
Do not place objects on top of the switch.
Do not expose the switch to moisture or water.
Ensure that the site is in a dust-free environment.
Do not install the switch in a wiring or utility box because it might
overheat and fail from inadequate airflow.
You should use dedicated power circuits or power conditioners to
supply reliable electrical power to the network devices.
Warning
Switches should not be stacked on a table or desktop. They could
present a physical safety hazard if you need to move or replace
switches. E91

Troubleshooting
This chapter contains information on how to troubleshoot the switch if a
problem occurs.
Note
For further assistance, please contact Allied Telesis Technical
Support at www.alliedtelesis.com/support.
Problem 1: The power LED on the front of the switch is off.
Solutions: The unit is not receiving power. Try the following:
Verify that the power cord is securely connected to the power
source and to the AC connector on the back panel of the switch.
Verify that the power outlet has power by connecting another
device to it.
Try connecting the unit to another power source.
Try a different power cord.
Verify that the voltage from the power source is within the required
levels for your region.
Problem 2: All of the port LEDs are off even though the ports are
connected to active network devices.
Solution: The switch is probably operating in low power mode. To toggle
on the LEDs, press the ecofriendly button on the front panel for 1 to 4
seconds.
Problem 3: The Link/Activity/Speed LED for an SFP transceiver is off.
Solutions: The fiber optic port on the transceiver is unable to establish a
link to a network device. Try the following:
Verify that the remote network device connected to the fiber optic
port is operating properly.
Verify that the fiber optic cable is securely connected to the port on
the media converter channel and to the port on the remote network
device.
Check that the SFP module is fully inserted in the slot.
Verify that the operating specifications of the fiber optic ports on
the SFP transceiver and the remote network device are
compatible.
Chapter 3: Troubleshooting
46
Verify that the correct type of fiber optic cabling is being used.
Verify that the port is connected to the correct fiber optic cable.
This is to eliminate the possibility that the port is connected to the
wrong remote network device, such as a powered off device.
Try connecting another network device to the fiber optic port using
a different cable. If the port is able to establish a link, then the
problem is with the cable or with the other network device.
Use the switch’s management software to verify that the port is
enabled.
If the remote network device is a management device, use its
management firmware to determine whether its port is enabled.
Test the attenuation on the fiber optic cable with a fiber optic tester
to determine whether the optical signal is too weak (sensitivity) or
too strong (maximum input power).
Problem 4: The switch functions intermittently.
Solutions: Check the system hardware status through the management
software:
Use the show system environment command in the Privileged
Exec mode to verify that the input voltage from the power source to
the switch is stable and within the approved operating range. The
unit will shut down if the input voltage fluctuates above or below
the approved operating range.
Use the show system environment command in the Privileged
Exec mode to verify that the fan is operating correctly.
Verify that the location of the switch allows for adequate airflow.
The unit will shut down if it is in danger of overheating.
Problem 5: A port’s Link/Activity/Speed LED is blinking.
Solutions: The link between the port and the network device is
intermittent. Try the following:
Connect another network device with a different cable to the port. If
the Link LED remains steady on, then the problem is with the
original cable or the network device.
If the problem is with an SFP transceiver, check that the
transceiver is fully inserted in the slot.
