H ARDWARE I NSTALLATION
1. Select the Site – Choose a location for your SMC2655W Wireless
Access Point. Usually, the best location is at the center of your wireless
coverage area, if possible within line-of-sight of all wireless devices.
2. Place the Access Point in a position that gives it maximum coverage.
Normally, the higher you place the antenna, the better the
performance.
3. Position the antennas in the desired positions. For more effective
coverage, position one antenna along the vertical axis and the other
antenna along the horizontal axis (the antennas emit signals along the
toroidal plane - and thus provide more effective coverage when
positioned along alternate axis).
4. Connect the Ethernet cable – The SMC2655W can be wired to an
Ethernet network through an Ethernet device such as a hub or a
switch using category 3, 4, or 5 UTP Ethernet cable and an RJ-45
connector.
5. Connect the power cable – Connect the power adapter cable to the
9 VDC power socket on the rear panel.
Warning: Use only the power adapter supplied with the SMC2655W.

SMCPWR-INJ P OWER
I NJECTOR
The SMCPWR-INJ* Power Injector allows the SMC2655W Access Point
to receive power from the connected Ethernet hub or switch and is used
with an Access Point that does not have access to a standard power outlet.
Follow these steps to install the Power Injector:
1. Connect the power adapter cable to the Power Injector.
2. Plug the power cord into a power outlet. The LED on the Power
Injector will light.
3. Connect an Ethernet cable from your Ethernet hub/switch to the
network port on the Power Injector.
4. Connect another Ethernet cable from the Access Point port on the
Power Injector to your Access Point.
*Sold separately
Note: The SMCPWR-INJ is designed for use with the SMC2655W
Access Point only. Using the Power Injector with any other
Ethernet device may damage the device.

S YSTEM C ONFIGURATION
Your SMC2655W is a plug and Play device. This means that, in most cases,
you will not need to configure it.
The SMC2655W Access Point includes an SNMP agent that is accessible
through an SNMP manager application (EZ Connect Wireless AP
Manager.) The SNMP agent supports read-write and read-only modes.
The diskette labeled “Utility Diskette” contains a utility program for the
EZ Connect Wireless Access Point. The latest version may be downloaded
from the download site specified on the back cover of this manual.
Warning: Back up your utility diskette and use the copy as the working
diskette to protect the original from accidental damage.
The SMC2655W can be configured over an Ethernet network. Connect
the SMC2655W to a network device such as a hub or switch. Install and
run the utility program as described in the following section.
