Installation Precautions
WARNING ■Wall-mount the switches with network ports facing up (away from
the floor) or down (toward the floor). Do not wall-mount any of
the switches with the ventilation ducts facing up or down.
Cautions ■Use only the AC/DC power adapter supplied with the switch for
connection to an AC power source.
■If your installation requires a different power cord than the one supplied
with the switch, ensure the cord is adequately sized for the switch’s
current requirements. In addition, be sure to use a power cord displaying
the mark of the safety agency that defines the regulations for power cords
in your country. The mark is your assurance that the power cord can be
used safely with the switch. If the supplied power cord does not fit,
contact HP networking support.
■When installing the switch, the AC outlet should be near the switch and
should be easily accessible in case the switch must be powered off.
■Ensure the switch does not overload the power circuits, wiring, and
over-current protection. To determine the possibility of overloading the
supply circuits, add together the ampere ratings of all devices installed on
the same circuit as the switch and compare the total with the rating limit
for the circuit. Maximum ampere ratings are usually printed on the devices
near the AC power connectors.
■Do not install the switch in an environment where the operating ambient
temperature might exceed 40°C (104°F). This includes a fully-enclosed
rack. Ensure the air flow around the sides and back of the switch is not
restricted. Leave at least 7.6 cm (3 inches) for cooling.
■For indoor use only. For safe and reliable operation, do not install the
switch or LAN cables outdoors.

Installing the Switch
Installation Procedures
Note The switches do not have a power switch. They are powered on when the
external AC/DC power adapter is connected to the switch and the adapter
power cord to a power source. The external AC/DC power adapter
automatically adjusts to any voltage between 100-240 volts and either 50 or
60 Hz.
If your installation requires a different power cord than the one supplied with
the switch, be sure the cord is adequately sized for the switch’s current
requirements. In addition, be sure to use a power cord displaying the mark of
the safety agency that defines the regulations for power cords in your country.
The mark is your assurance that the power cord can be used safely with the
switch. If the supplied power cord does not fit, contact HP networking
support.
Caution Use only the AC/DC power adapter and power cord, supplied with the switch.
Use of other adapters or power cords, including those that came with other
HP networking products, may result in damage to the equipment.
2. Check the LEDs on the switch as described below.
Figure 2-2. Checking the LEDs

Installation Procedures
LED Behavior
After Initialization:
• The Power LED remains on.
• The port Link/Act LEDs on the front of the switch go into their normal
operational mode:
– If the ports are connected to active network devices, the Link/Act
LEDs stay on or may be blinking to indicate port activity.
– If the ports are not connected to active network devices, the
Link/Act LEDs will stay off.
If the LED display is different than what is described above, the self test
has not completed correctly. Refer to chapter 4, “Troubleshooting” for
diagnostic help.
3. Mount the Switch
After the switch passes self test, it is ready to be mounted in a stable location.
The switch can be mounted in these ways:
■on a horizontal surface
■on a wall
Wall Mounting
You can mount the switch on a wall. A special kit for wall mounting is included
with the switch.
Caution The switch should be mounted only to a wall or wood surface that is at least
1/2-inch (12.7 mm) plywood or its equivalent.
1. In the required location, mark the position for the mounting screws.
2. Use a Phillips #2 (cross-head) screwdriver and two of the included
∅3.5mm tapping screws to mount the switch on the wall or wood surface.
