Choosing a Site for the Switch
Review these site recommendations and requirements.
Before installing the switch in an equipment rack, verify that the
rack is safely secured so that it will not tip over. Devices in a rack
should be installed starting at the bottom of the rack, with the
heavier devices near the bottom.
Before installing the switch on a table, verify that the table is level
and stable.
Before installing the switch on a wall, verify that the wall’s material
is strong enough to hold the switch’s weight. You should position
the device so that it can be screwed into the wall’s framing timber
or equivalent structural element.
The power outlet should be located near the switch and be easily
accessible.
The site should allow for easy access to the ports on the front of
the switch so that you can easily connect and disconnect cables,
and view the port LEDs.

The site should allow for adequate air flow around the unit and
through the cooling vents on the side panels.
Do not place objects on top of the switch.
The site should not expose the switch to moisture or water.
The site should be a dust-free environment.
The site should use dedicated power circuits or power
conditioners to supply reliable electrical power to the network
devices.
Do not install the switch in a wiring or utility box without adequate
airflow and cooling. The switch might overheat and shutdown.
Direction of Ventilation in the Switches
The GS950/18PS V2, GS950/28PS V2, and GS950/52PS V2
Switches have internal ventilation fans. Airflow is from left to right,
when facing the front of the switch.
Note: The GS950/10PS V2 Switch does not have ventilation fans.
The site must provide sufficient airflow to prevent overheating of the
device.
Installing the Switch
Installing the Switch on a Desk or Table
To install the switch on a desk or table, perform the following
procedure:
1. Place the switch upside down on the table.
2. Affix the bumper feet to the four corners on the bottom panel of
the switch.
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

anchors.
Cross-head screwdriver (not provided)
Flat-head screwdriver (not provided)
Stud finder for a wooden wall, capable of identifying the middle of
wall studs and hot electrical wiring (not provided)
Drill and 1/4” carbide drill bit for a concrete wall (not provided)
To install the switch on a wall, perform the following procedure:
1. Place the switch on a table.
2. If the four bumper feet are attached to the bottom of the switch,
remove them with a flat-head screwdriver.
3. Install the two brackets to the sides of the unit with the eight
screws included with the switch.
Warning: The device should be installed on the wall by
a qualified building contractor. Serious injury to yourself
or others or damage to the equipment may result if it is
not properly fastened to the wall.  E105
Caution: The supplied screws and anchors might not be
suitable for all walls. A qualified building contractor
should determine the hardware requirements of your
wall before installing the switch.  E88

12 GS950PS V2 Series Quick Installation Guide
Note: If you need to drill holes in the wall for the screws, perform
steps 4 to 8. Otherwise, go to step 9.
4. Have a person hold the switch on the wall at the selected location
while you use a pencil to mark the wall with the locations of the
four screw holes in the two brackets.
5. Place the switch on a table.
6. Use a stud finder to check for hot electrical wires at the locations
of the screw holes.
7. Use an appropriate drill to drill the holes. The dimensions of the
supplied anchors are 4x22.2mm. The dimensions of the supplied
screws are 3.5x16mm.
8. If the wall material requires anchors, insert the anchors into the
screw holes.
9. Have another person hold the switch at the selected wall location
while you secure it to the wall with four screws.
Warning: Do not install the switch on a wall near hot
electrical wires.

10. Go to “Ports” next.
Ports
Ethernet Copper Cable Specifications
The minimum cable requirements for the copper Ethernet ports are.
10Mbps or 100Mbps: Standard TIA/EIA 568-B-compliant
unshielded Category 3 cabling.
1000Mbps: Standard TIA/EIA 568-A-compliant Category 5 or TIA/
EIA 568-B-compliant unshielded Enhanced Category 5 (Cat 5e)
cabling.
Cabling Ethernet Copper Ports
Observe the following guidelines when connecting Ethernet copper
cables to the ports on the switch:
The connectors on the cables should fit snugly into the ports, and
the tabs should lock the connectors into place.
The default speed setting for the ports is Auto-Negotiation. This
setting is appropriate for ports connected to network devices that
also support Auto-Negotiation.
The ports must be set to Auto-Negotiation, the default setting, to
operate at 1000Mbps.
The ports support half- and full-duplex at 10Mbps and 100Mbps.
The ports support only full-duplex at 1000Mbps.

14 GS950PS V2 Series Quick Installation Guide
Do not attach cables to ports of static or LACP port trunks until
after configuring the switch trunks. This is to prevent the ports
from forming network loops that can adversely affect network
performance.
PoE+ is enabled by default on the ports on the switches.
Installing SFP Transceivers
Here are general installation guidelines:
You can install SFP transceivers while the switch is powered on.
For a list of supported transceivers, refer to the product’s data
sheet on the Allied Telesis web site at www.alliedtelesis.com.
The operational specifications and fiber optic cable requirements
are included with the transceivers.
Install the transceivers before connecting their fiber optic cables.
Fiber optic transceivers are dust sensitive. Always keep the dust
cover in the optical ports when a fiber optic cable is not installed.
Unnecessary removal and insertion of transceivers can lead to
premature failures.
To install SFP transceivers, perform the following procedure:
1. To install a transceiver in a top port, position it with the Allied
Telesis label facing up. To install it in a bottom port, position it
with the label facing down.
Warning: Transceivers can be damaged by static
electricity. Be sure to observe all standard electrostatic
discharge (ESD) precautions, such as wearing an
antistatic wrist strap, to avoid damaging the devices. 
E86

GS950PS V2 Series Quick Installation Guide 15
2. Slide the transceiver into the port until it clicks into place.
To attach the fiber optic cable to the transceiver, continue with
the next step. Otherwise, repeat steps 1 and 2 to install the
remaining transceivers in the switch.
3. Remove the dust cover from the transceiver.
4. Connect the fiber optic cable to the transceiver. The connector
should fit snugly into the port, and the tab should lock the
connector into place.
5. Repeat this procedure to install additional transceivers.
6. Go to “Powering On the Switch” next.
Powering On the Switch
1. Install the power cord retaining clip on the AC power connector
on the rear panel of the switch, and raise the clip.
2. Connect the power cord to the connector and lower the retaining
clip to secure the power cord.
Warning: Power cord is used as a disconnection device.
To de-energize equipment, disconnect the power cord.
 E3

16 GS950PS V2 Series Quick Installation Guide
3. Plug the other end of the power cord into an appropriate AC
power source.
4. Wait two minutes for the switch to start its management software.
5. Verify that the POWER LED is green. If the LED is off, see
“Troubleshooting” on page 22.
Starting the First Management Session
This procedure explains how to start the first management session on
the switch. The procedure assumes that your network has a DHCP
server.
Note: For instructions on how to start the first management session
in a network without a DHCP server, refer to the GS950PS V2
Gigabit Ethernet Switch Series Installation Guide. The guide is
available at www.alliedtelesis.com/us/en/services-support.
1. Assign the switch an IPv4 address on the DHCP server on the
network. (The MAC address of the switch is provided on a label
on the rear panel.)
2. Connect at least one port on the switch to a network device, such
as another Ethernet switch.
3. Power on the switch. Refer to “Powering On the Switch” on
page 15.
4. Wait two minutes. The switch start its management software and
obtains its IPv4 address from the DHCP server.
5. Start the web browser on your workstation.
6. Enter the IPv4 address of the switch in the URL field of the
browser. This is the IPv4 address you assigned the switch on the
DHCP server.
