Ethernet and Console Ports
The AP121 and AP141 models have one RJ-45 10/100/1000Base-T/TX Ethernet port and an RJ-45 console
port.
The pin assignments in the 10/100/1000Base-T/TX Ethernet port follow the TIA/EIA-568-B standard (see
Figure 2
on page 66 ). The port accepts standard types of Ethernet cable—cat3, cat5, cat5e, or cat6—and can
receive power over the Ethernet cable from PSE (power sourcing equipment) that is 802.3af-compatible.
Such equipment can be embedded in a switch or router, or it can come from purpose-built devices that
inject power into the Ethernet line en route to the AP. Because the PoE port has autosensing capabilities, the
wiring termination in the Ethernet cable can be either straight-through or cross-over. Aerohive provides
several PoE injectors as accessories that you can order: AH-ACC-INJ-20W-EU, AH-ACC-INJ-20W-UK,
AH-ACC-INJ-20W-US, AH-ACC-INJ-20W-AU, and AH-ACC-INJ-20W-IL.
If an AP is connected to both an AC power source and PSE, the AC power source takes priority. If the device
loses power from that source, it automatically switches to PoE. If the AC power comes back online, the AP
automatically switches back to AC. Each time the AP switches from one power source to another, it must
reboot.
Through the RJ-45 console port, you can make a serial connection between your management system and
the AP. The pin-to-signal mapping of the RJ-45 console port is the same as that for the AP340, which is shown
in Figure 2 on page 66 . Similarly, cabling and connection details for the AP121 and AP141 are the same as
those for the AP340 (see Figure 2 on page 11 )
Status Indicator
The AP121 and AP141 have a triangular status indicator light on the top left corner of the chassis. The colors
of this light indicate the following states of activity:
• Dark : There is no power or the status indicator is disabled.
• Amber (flashing): This is an alert that indicates that the device is performing a firmware upgrade. Do
not power off the device during this process.
• Amber (steady): This is an alert that indicates that the CAPWAP connection has not been
successfully established, or the device is booting or shutting down.
• White : The device is powered on, a successful CAPWAP connection has been made, and the
firmware is operating normally.
Port LEDs
The ETH0 port has two status LEDs to indicate port operation (yellow for 10/100 Mbps and green for 1000
Mbps). The meanings of the LED colors and patterns are described here:
• Dark : No link is detected for this port.
• Yellow (steady): This port has made a successful 10/100 Mbps link.
• Yellow (flashing): This port is sending and receiving traffic at 10/100 Mbps.
• Green (steady): This port has made a successful 1000 Mbps link.
• Green (flashing): This port is sending and receiving traffic at 1000 Mbps.
