Note: APs do not support daisy-chain configurations. Do not connect one AP to another AP.
Note: The solid surface mounting option requires Cat 5 cable that does not have strain relief. The
other mounting options can use Cat 5 cable with or without strain relief.

Table 1-1 Access Point LEDs
LED Appearance Meaning
Health Solid green All the following are true:
• Management link with a switch is operational.
• AP has booted.
• AP has received a valid configuration from a switch.
• At least one radio is enabled or is in sentry mode.
Solid amber AP is waiting to receive boot instructions and a configuration
file from a switch.
Alternating green and
amber
AP is booting and receiving its configuration file from a switch.
Radio 1
Radio 2
Solid green A client is associated with the radio.
Blinking green Associated client is sending or receiving traffic.
Blinking amber Non-associated client is sending or receiving traffic.
Alternating green and
amber
Radio is unable to transmit. This state can occur due to any of
the following:
• Excessive radio interference in the environment is preventing
the radio from sending beacons.
• The radio has failed.
Unlit Means one of the following:
• Radio is disabled.
• Radio is enabled, but no clients are associated with the radio
and there is no traffic activity.
Note: Install the Cat 5 cables for the access point at the installation site before installing the access
point itself. During installation, you will insert the Cat 5 cable(s) into the access point port(s) before
attaching the access point to the bracket.
