Note - Please refer to Uplink Modules for the operations and behaviour of the expansion
modules installed on these devices.
Note - When connecting to a slave switch, Device Manager does not automatically replace
the master switch image in the main window with the slave switch image. The same is true
when returning to the master switch from the slave switch. To view the updated image,
click on the Refresh option under the Agent menu.
Note - AT-8550SP: If a copper SFP is inserted in either of the SFP module expansion slots,
status information will be reflected on its corresponding redundant RJ-45 port image
regardless of whether it is the RJ-45 or the SFP port that is actually in operation.
Note - The SNMP Client on the device may take a while to respond or may stop responding
altogether after several SNMP commands have already been issued. When this happens, it
may take a while for device information to be displayed in Device Manager. Error messages
may also be encountered during Get MIB Value and Set MIB Value operations.
Agent Menu
From the Agent menu, you can view and edit the system information for the device, or log
into the CLI using Telnet.
System Info
Displays basic system information, including system name, location, contact and
description.
Note - The current firmware version allows the user to enter up to 38 characters
for the System Location parameter.
Note - Configuring the System Contact, System Name and System Location
parameters may sometimes result in the error message: "The error occurred with
'Set' operation. Error: gen Error." However, the values are still set successfully.
