16 3.3 Modes of Operat ion The module has the following FIP S approved modes of operations: • Remote AP (RAP) FIPS mode – W hen the module is configured as a Remote AP, it is intended to be deploy ed in a remote location (relative to the Mobility Controller ).
17 6. If the staging contro ller does not p rovide PoE, either ensure the presence of a P oE injector for the LAN connection bet ween the module and the co ntroller, or ensure t he presence o f a DC po wer supply appropriate to the particular model of the module.
18 7. Connect the module via an Ethernet cable to the sta ging controller; no te that this should b e a direc t connection, with no intervening net work or devices; i f Po E is being supplied by an inj ector, th is represents the o nly exception.

20 represents the o nly exception. That is, nothing o ther than a P oE injector should b e present b etween the module and the sta ging controller. 8. Once t he module is co nnected to the co ntroller by the Ethernet cable, navigate to the Configuration > Wireless > AP Installation page, where you sho uld see an entr y for the AP.
21 3.5 Logical Interfaces The ph ysical interfaces are d ivided into logical interface s defined b y FIP S 140 -2 as described in the following table. FI PS 140-2 Logical Interface Module Physical Interfa ce Data Input Interface 10/100/1000 Ethernet P orts 802.
22 4 Roles, A u thentication an d Services 4.1 Roles The module s upports the roles of Cr ypto Officer, User , and Wireless Client; no additio nal roles ( e.g., Maintenance) are suppo rted. Ad ministrative op erations car ried out by the Aruba Mobility C ontroller map to the Crypto Officer role.
23 4.1.2 User Authentication Authentication for the User role depends on the module configuration. When the module is configured as a Remote Mesh Portal FIP S mode and Re mote Mesh P oint FIP S mode, the U ser role is authenticated via t he WPA2 p re-shared ke y.
24 Authentication Mechanis m Mechanis m Strength Wireless Client WPA2-PSK (Wireless Client role) For WPA2 -PSK there are at least 95^1 6 (=4.4 x 10^31) possible combinations. In order to test a guessed key, the attac ker must complete the 4-way handshake with the AP.
25 4.2 Services The module provides vario us services depending o n role. These are descr ib ed below. 4.2.1 Crypto Officer Services The CO role in each of FIP S modes defi ned in section 3.
26 Service Description CSPs Accessed ( see secti on 6 below for complete descrip tion of CSPs) Creation/use of secure management session bet ween module and CO The module supports use of IPSec for securing the management channel.

34 7 Self T es t s The module perfor ms the follo wing Self Tests af ter being config ured into either Re mote AP mode or Remote Mesh P ortal mode. The module perfor ms both po wer-up and co nditional self -tests. In t he event an y self-test fails, the module enters an error state, lo gs the error, and reboo ts automatically.
35 Self-test results are written to the serial console. In the event of a K ATs failure, the AP logs different messages, dep ending on the error. For an ArubaOS OpenSS L AP module and ArubaOS c ryptog.
