Status lights
The status lights provide different information depending on whether the AP is operating in
autonomous mode or controlled mode. For more information on these modes, see “About controlled
mode and autonomous mode” (page 12).
6 Preparing for installation
Autonomous mode
In autonomous mode, the status lights indicate the following:
DescriptionStateLight
The AP has no power.OffPower
The AP is fully operational.On
The AP is starting up. If the Power light continues to blink after several minutes, it indicates
that the software failed to load. Reset or power cycle the AP. If this condition persists,
contact HP Support.
Blinking
The AP is fully operational.OnInfo
The port is not connected or there is no activity.OffEthernet
The port is transmitting or receiving data.Blinking
The radio is transmitting or receiving data.BlinkingRadio 1, 2
Controlled mode
During startup/discovery in controlled mode, the status lights indicate the following:
DescriptionStatus light behavior
The AP is starting up.Power light blinks every two seconds.
The AP is looking for an IP address, or building the list of
VLANs on which to perform controller discovery. The
management tool is available until discovery occurs.
Power light blinks once per second.
The AP has obtained an IP address and is attempting to
discover a controller.
Power, Info, and Ethernet lights blink in sequence from left
to right.
The AP has found a controller and is attempting to establish
a secure management tunnel with it.
Power light is on. Info and Ethernet lights blink alternately.
The AP has received a discovery reply from two or more
controllers with the same priority setting. The AP is unable
to connect with either controller until the conflict is resolved.
Power and Info lights blink alternately and quickly. Radio
lights are off.
The AP is attempting to establish a local mesh link to a
master node.
Power light and one Radio light blink slowly. (This will be
the light for the radio on which the local mesh link is being
established.)
The AP is attempting to establish wired connectivity.Power and Ethernet lights blink slowly.
Once the discovery process is complete, and the AP has established a secure management tunnel
to a controller, the Power light remains on and the Ethernet and Radio lights blink to indicate the
presence of traffic.
Ports
• Ethernet port: Auto-sensing 10/100/1000 BaseT Ethernet port with an RJ-45 connector. The
port supports Power over Ethernet (PoE) 802.3af.
• Console port: Standard console (serial) port with a DB-9 (female) connector. To connect to a
computer, use a standard (straight-through) serial cable (male-to-female). For details, see
Console Ports in the MSM3xx / MSM4xx APs Configuration Guide. There is no need to use
the Console port for initial configuration.
WARNING! Never connect the Console port to an Ethernet switch or PoE power source. This may
damage the AP. Connect it only to other serial ports via a DB-9 to serial port adapter.

Radio and antenna
The AP has two radios. The lower flap contains three antennas (MIMO) for Radio 1, which by
default is set to 802.11n (5 GHz) mode. The upper flap contains two antennas for Radio 2, which
by default is set to 802.11b/g mode. Optional external antennas are available from HP.

For 802.11n on Radio 1, always install three antennas (MIMO) on the Radio 1 antenna connectors
(A, B, C).
Reset button
• Press and quickly release the button to reset the AP.
• To reset the AP to factory defaults, press the button until the status lights blink three times, then
release. Following a reset to factory defaults, the AP starts up in controlled mode with a an
option to switch it to autonomous mode.
Important information to read before installing
For indoor installation only.
Professional installation required
WARNING! Prior to installing or using the AP, consult with a professional installer trained in RF
installation and knowledgeable in local regulations including building and wiring codes, safety,
channel, power, indoor/outdoor restrictions, and license requirements for the intended country. It
is the responsibility of the end user to ensure that installation and use comply with local safety and
radio regulations.
Surge protection and grounding
WARNING! If you plan on connecting an outdoor antenna to the AP, make sure that proper
lightning surge protection and grounding precautions are taken according to local electrical code.
Failure to do so may result in personal injury, fire, equipment damage, or a voided warranty. The
HP hardware warranty provides no protection against damage caused by static discharge or a
lightning strike.
Cabling
You must use the appropriate cables, and where applicable, surge protection, for your given
region. For compliance with EN55022 Class-B emissions requirements, use shielded Ethernet
cables. Cat 5e (or better) cabling is required.
Plenum installation
The AP can be installed in a plenum (UL2043 rating). The AP is suitable for use in environmental
air space in accordance with Section 300-22(C) of the National Electrical Code, and Sections
2-128, 12-010(3) and 12-100 of the Canadian Electrical Code, Part 1, CSA C22.1.
