Mesh Network Components
• Port 0 (g0) is a Power over Ethernet (PoE) input port–PoE (in)
• Port 1 (g1) is a PoE output port–PoE (out)
• Port 2 (g2) is a cable connection
• Port 3 (g3) is a fiber connection
You can query the status of these four interfaces in the controller CLI and Cisco WCS.
In the controller CLI, the show mesh env summary command is used to display the status of the ports.
• The Up or Down (Dn) status of the four ports is reported in the following format:
– port0(PoE-in):port1(PoE-out):port2(cable):port3(fiber)
• For example, rap1522.a380 in the display below shows a port status of UpDnDnDn. This indicates
that:
– PoE-in port 0 (g0) is Up, PoE-out port 1 (g1) is Down (Dn), Cable port 2 (g2) is Down (Dn) and
Fiber port 3 (g3) is Down (Dn).

Multiple Power Options
Power options include:
• 90 to 480 VAC streetlight power
• 12 V DC
• Cable power
• PoE using a separate power injection system
– For details on the power injection, its specifications, and installation refer to
http://www.cisco.com/en/US/docs/wireless/access_point/1520/power/guide/1520pwrinj.html
• Internal battery backup power
• 802.3af-compliant PoE out to connect IP devices (such as a video cameras)
Battery Backup Module (Optional)
An optional battery backup module (part no. AIR-1520-BATT-6AH) is available for AP1520s.
The integrated battery can be used for temporary backup power during external power interruptions. The
battery run time for AP1520s is as follows:
• 3-hour access point operation using two radios at 77
o
F (25
o
C) with PoE output port off
• 2-hour access point operation using two radios at 77
o
F (25
o
C) with PoE output port on
The battery pack is not supported on the access point cable configuration.
