Here’s a list of blinking leds on HP MSM accesspoints and HP 425 accesspoint.
I was tired of looking it up all the time, and since these are end-of-life I may well copy that information from HP to my site for my own purposes, and perhaps for yours too.
MSM Access Points Controlled mode Power light blinks every two seconds. The AP is starting up. Power light blinks once per second. The AP is looking for an IP address, or building the list of VLANs on which to perform discovery. The management tool is available until discovery occurs. Power, Ethernet, and Radio lights blink in sequence from left to right. The AP has obtained an IP address and is attempting to discover a controller. Power light is on. Ethernet and Radio lights blink alternately. The AP has found a controller and is attempting to establish a secure management tunnel with it. Power and Ethernet lights blink alternately and quickly. Radio lights are off. The AP has received a discovery reply from two or more controllers with the same priority setting. It is unable to connect with either controller until the conflict is resolved. Power and Radio lights blink slowly. The AP is attempting to establish a local mesh link to a master node. Power and Ethernet lights blink slowly. The AP is attempting to establish wired connectivity. All three blinking together rapidly The AP is in TFTP mode. This is a disaster recovery mode, and not used in normal operation. To put AP back to normal mode restore it to factory default settings. If this does not restore normal operation, contact Technical Support. Autonomous mode Power Off The AP has no power. Power Blinking 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. Power On The AP is fully operational. Ethernet Off The port is not connected or there is no activity. Ethernet Blinking The port is transmitting or receiving data. Radio Blinking The radio is transmitting or receiving data. All three Blinking together rapidly The AP is in TFTP mode. This is a disaster recovery mode, and not used in normal operation. To put AP back to normal mode restore it to factory default settings. If this does not restore normal operation, contact Technical Support.
HP 425 Green Flashing 1 flash/sec. The AP is booting. Fading in/out At least one client is connected to the 2.4 GHz radio. Blue Flashing 2 flashes/sec. The AP is updating its system software image. Blue Flashing 2 sec. on / 2 sec. off The AP is booted and is registered to the controller. There is no client connected. Blue Fading in/out At least one client is connected to the 5 GHz radio. Orange On for more than 20 sec. An initialization exception has occurred. Orange Flashing 1 flash/sec. There is a problem with the radio module. Orange Flashing 2 flashes/sec. Both radios are disabled or the Ethernet port is disabled while no local mesh peer exists. Green/Blue Alternately fading green and blue Clients are connected to both the 2.4 GHz and 5 GHz radios.
Hope this helps you.
