Operational Notes
The following operational notes are relevant to this release.
Battery Charge Information is not Available for AP1510s with Power Supply 1.01d Firmware
An AP1510 with an Alpha FlexNet MPS30-48C-SL power supply must have firmware version 1.02d or
greater to supply information about its remaining charge to the controller and Cisco WCS. Otherwise,
the controller and WCS display incorrect battery information.

To upgrade your power supply to 1.02d (or greater) firmware, return the power supply to an Alpha
service center (Argus).

Monitoring Port LED Status on an AP1520
When physically disconnecting a cable from an AP1520, the port LED associated with that connection
might remain lit for up to 3 seconds.

AP1520 Support for Four Gigabit Ethernet Ports
The AP1520 supports four Ethernet interfaces (g0–PoE in, g1–PoE out,g2–Cable, g3–Fiber). Refer to
the
the
for details how the CLI and GUI displays are
modified to report status on the four Ethernet ports.
Parent Selection Differences Between AP1520 and AP1510
When operating as a MAP, the AP1520 generally prefers to select a parent that shares the same bridge
group name (BGN), rather than a wired interface (uplink) to the controller. This approach is different
from the AP1510 which always places a higher priority on selecting a parent with a wired connection.

from the AP1510 which always places a higher priority on selecting a parent with a wired connection.
Additionally, when an AP1520 connects to a parent with a default (null) BGN, the AP1520 disables the
Ethernet Bridging feature to prevent a potential bridge loop. An AP1510 does not disable Ethernet
Bridging.

To ensure smooth operation, configure a bridge group name for the AP1520 and verify that the mesh
access point is connecting to a parent on the same bridge group to allow Ethernet bridging.
