36 Brocade Mobility 7131 Access Point Product Reference Guide

53-1002517-01

When users purchase a WLAN solution, they often need to place access points in obscure

locations. In the past, a dedicated power source was required for each access point in addition to

the Ethernet infrastructure. This often required an electrical contractor to install power drops at

each access point location. The Power Injector merges power and Ethernet into one cable, reducing

the burden of installation and allowing optimal access point placement in respect to the intended

coverage area.

The Power Injector (Part No. AP-PSBIAS-1P3-AFR) is a high power POE Injector delivering up to 30

watts. The access point can only use a Power Injector when connecting the unit to the access

point’s GE1/POE port. The Power Injector is a separately ordered component and not shipped with

an existing access point SKU.

A Mobility 7131 Access Point and Mobility 7131N Access Point can also be used with the 3af power

injector (AP-PSBIAS-1P2-AFR). However, AP functionality is limited when powered by an

AP-PSBIAS-1P2-AFR, since the AP has Ethernet connectivity limited to only the GE1 port.

The Brocade Mobility access point Power Supply (Part No. 50-14000-247R) is not included with the

access point and is orderable separately as an accessory. If the access point is provided both POE

power over the GE1/POE connection, as well as the 50-14000-247R power supply concurrently, the

access point will source power from the 50-14000-247R supply only. Disconnecting AC power from

the

50-14000-247R, causes the AP to re-boot before sourcing power from the POE power injector. If the

AP is operating using injector supplied power, the AP will not automatically reboot if an AC adapter

is connected. The AP continues to operate with power supplied from the AC adapter without change

to the AP operating configuration. If using AC adapter supplied power and a change to the AP’s

operating configuration is warranted (for example, if needing to access the GE2 port), the AP needs

to be manually rebooted by the customer.

CAUTION

The access point supports any standards-based compliant power source (including non-Brocade

Mobility power sources). However, using the wrong solution (including a POE system used on a

legacy Brocade Mobility access point) could either limit functionality or severely damage the

access point and void the product warranty.
