Expansion Module Notes
• AT-View Plus Device Manager cannot distinguish between the AT-A45/xx, AT-A47, and
AT-STACKM expansion modules. All are displayed with the same GIF image.
• When both the AT-A45 and AT-A46 expansion modules are present on a device, the AT-
A45 port image may show up as green and its Port Speed parameter may reflect the value "1
Gbps" even if there is no connection established on the port. To reflect the correct port image
color and port speed, restart the device. This applies to the following devices:
AT-8016F/xx
AT-8024M
AT-8088/xx
• Connection cannot be established on the AT-A46 expansion module port if the Port Speed
and Mode parameter is set to "auto 1Gbps".
• When the Port Speed and Mode parameter of the AT-A46 expansion module port is set to
"auto 10/100Mbps" and the port is connected to a 10/100Mbps full-duplex port on another
device, its corresponding Duplex LED on the device image turns orange instead of green.
• The Spanning Tree Protocol (STP) does not work for the AT-A46 expansion module when it
is installed on an AT-8016F/ST device. As a result, the Port State parameter of the AT-A46
expansion module port will never be set to 'blocking' and the port image will never turn
yellow.
• Connection between an AT-A47 expansion module port that is configured to operate at
1Gbps full duplex and a port on another device can only be established if the port on the
other device is configured to auto-negotiate.
• For the AT-A47 expansion module, AT-View Plus Device Manager will only display the
AT-A45/AT-A47/AT-STACKM shared GIF image if a GBIC module is present in the GBIC
slot.
