2 Preparing for Installation

It is advisable to connect the power (if using an external power supply) and check the Ethernet cables

and LEDs before installing the access

point in a hard-to-reach location. Additionally, observe the

following before mounting or connecting the access point:

• Cabling Make sure that standard Category 5 cable with straight-through signaling is

installed at the site before you install the access point.

Make sure that the cable is highly flexible and that there is no extra covering

on the RJ-45 connector that could prevent the cable from being routed

through the mounting bracket

• Power Power must be supplied via an 802.3af Power Over Ethernet (PoE)-compliant

device. Removal of the Ethernet cable is the only method of disconnecting

power from the access point.

• MAC Address Record the access point MAC address in a safe place before the access point

is installed in a hard-to-reach location. The MAC address is printed on the

back of the access point. Additional MAC address labels are shipped with the

access point.
