About CablesAbout Cables
• You will run one CAT-5 Ethernet cable from the Nortel Networks WLAN - Access Point to the
(UNUSED PRODUCT), another network device, or a PoE injector/hub.
When the Nortel Networks WLAN - Access Point will be mounted below the ceiling using the
ceiling mount or wall mount brackets, you may have to drill a hole into the ceiling plenum to
run the CAT-5 cable to the wiring closet. When the CAT-5 cable cannot be run through the ceil-
ing plenum, find another path to route the cable from the Nortel Networks WLAN - Access Point
to the wiring closet.
When the Nortel Networks WLAN - Access Point will be mounted above the ceiling using the
ceiling mount or wall mount brackets, run the CAT-5 cable to the wiring closet through the ceil-
ing plenum. When the CAT-5 cable cannot be run through the ceiling plenum, find another path
to route the cable from the Nortel Networks WLAN - Access Point to the wiring closet.
• When you are powering the Nortel Networks WLAN - Access Point from AC power, route the
power supply cable from the AC convenience outlet to the Nortel Networks WLAN - Access
Point. Make sure you secure the AC power plug so it will be difficult for people to pull on the
power cord or unplug the power supply from the AC power outlet.
• When you are powering the Nortel Networks WLAN - Access Point from a PoE source ((UNUSED
PRODUCT), another network device, or a PoE injector/hub), you do not need to route a
separate power cable to the Nortel Networks WLAN - Access Point, because the Nortel Networks
WLAN - Access Point will receive its power across the CAT-5 Ethernet cable. Return the power
supply to the wireless network planner/manager.
About External AntennasAbout External Antennas
• The AS-1200-BG-INT and AS-1200-ABG-INT Nortel Networks WLAN - Access Points are
designed to be used exclusively with the internal high-gain antennas, and have no provisions
for external antennas.
Note: As described in the External-Antenna Airespace Access Point Quick Installation Guide,
the AS-1200-BG-INT, and AS-1200-ABG-INT Nortel Networks WLAN - Access Points and
AS-1200-ABG-EXT-RE Remote Edge Access Points have jacks for external antennas.
About Mounting OptionsAbout Moun ting Options
Note: Because the Nortel Networks WLAN - Access Point internal antennas have been
designed to reduce inter-floor interference, it is strongly recommended that you mount the
Nortel Networks WLAN - Access Point standing or hanging straight up or down.
Note: You can mount the Nortel Networks WLAN - Access Points in the ceiling plenum or below
the ceiling using the ceiling mount base or wall mount brackets, but the Nortel Networks
WLAN - Access Points perform best when mounted below the ceiling.
Note: Plenum-mounted Nortel Networks WLAN - Access Points and Remote Edge Access Points
MUST BE powered using Power Over Ethernet (POE) to comply with safety regulations.
• When you are mounting the Nortel Networks WLAN - Access Point in the middle of a ceiling,
ceiling plenum, or hallway, you will typically use the color-coordinated ceiling-mount base to
stabilize the Nortel Networks WLAN - Access Point after it is mounted. Use the mounting base
to mark the sheet metal, drywall, or other screw locations.
The mounting base attaches to the bottom of the Nortel Networks WLAN - Access Point with
two supplied screws, and then the assembly slides and locks onto two sheet metal, drywall, or
other screws.
