Using Hot Standby Mode
Step 15 Also on the AP Radio Data Encryption page, select the same Authentication Types that are on the root
access point.
Step 16 On the AP Radio Advanced page, enter the root access point’s MAC address in the Specified access point
1 entry field.
Step 17 On the Express Setup page, select Repeater Access Point as the Role in Radio Network. The access
point reboots when you apply this setting.
Step 18 The status LED on the root access point should be steady green, indicating that at least one client device
is associated to it. The status LED on the repeater access point is steady green when it is associated to
the root access point and has client devices associated to it. The repeater’s status LED is steady for 7/8
of a second and off for 1/8 of a second when it is associated to the root access point but has no client
devices associated to it. The repeater access point should also appear as associated to the root access
point in the root access point’s Association Table.
Using Hot Standby Mode
Hot Standby mode designates an access point as a backup for a root access point. The standby access
point is placed near the access point it monitors and, with the exception of its IP address, it is configured
exactly the same as the monitored access point. The standby access point associates to the monitored
access point as a client and queries the monitored access point regularly through both the Ethernet and
the radio. If the monitored access point fails to respond, the standby access point takes the monitored
access point’s place in the network.
Except for the settings specified below, the standby access point’s settings should be identical to the
settings on the monitored access point. The standby access point must also be able to associate to the
root access point as a client. You use the Hot Standby page to set up the standby access point. Figure 12-2
shows the Hot Standby page.
