Cisco Systems 1240AG manual Power Sources

Chapter 1 Overview

Hardware Features

Power Sources

The access point can receive power from an external power module or from inline power using the Ethernet cable. The access point supports the IEEE 802.3af inline power standard and Cisco CDP Power Negotiation. Using inline power, you do not need to run a power cord to the access point because power is supplied over the Ethernet cable.

Warning This product must be connected to a Power over Ethernet (PoE) IEEE 802.3af compliant power source or an IEC60950 compliant limited power source. Statement 353

Caution Be careful when handling the access point; the bottom plate might be hot.

The access point supports the following power sources:

•Power module

•Inline power:

–Cisco Aironet Power Injector (AIR-PWRINJ3 or AIR-PWRINJ-FIB)

–An inline power capable switch, such as the Cisco Catalyst 3550 PWR XL, 3560-48PS, 3570-48PS, 4500 with 802.3AF PoE module, or the 6500 with 802.3AF PoE module

–Other inline power switches supporting the IEEE 802.3af inline power standard

Note Some switches and patch panels might not provide enough power to operate the access point with both 2.4-GHz and 5-GHz radios. At power-up, if the access point is unable to determine that the power source can supply sufficient power, the access point automatically deactivates both radios to prevent an over-current condition. The access point also activates a Status LED low power error indication and creates an error log entry (refer to the “Checking the Autonomous Access Point LEDs” section on page 3-2and the “Checking Basic Settings” section on page 3-3).

UL 2043 Certification

The access point has adequate fire resistance and low smoke-producing characteristics suitable for operation in a building's environmental air space, such as above suspended ceilings, in accordance with Section 300-22(c) of the NEC, and with Sections 2-128, 12-010(3) and 12-100 of the Canadian Electrical Code, Part 1, C22.1.

Caution Only the fiber-optic power injector (AIR-PWRINJ-FIB) has been tested to UL 2043 for operation in a building’s environmental air space; the AIR-PWRINJ3 power injector and the power module are not tested to UL 2043 and should not be placed in a building’s environmental air space, such as above suspended ceilings.

Anti-Theft Features

There are three methods of securing the access point:
