flashing amber on the inactive master card.
 Check to be sure that the operating parameters on the terminal or
the terminal emulation program have been set correctly. The
default settings for the RJ-45 serial terminal port are located in
“Using Local Management to Verify the Chassis” on page 214.
 Check to be sure that the terminal emulator application is
compatible with a VT-100 terminal.
Fault Condition 5: If the chassis has two AT-SBx31CFC960 Controller
Cards but the performance of the Ethernet line cards is slow or the SHOW
CARD command indicates that the inactive controller cards is not in the
Up-Up state, the chassis might have an old backplane that does not
support two controller cards. To determine whether this is the problem, try
the following:
 Examine the LEDs for slots 4 and 5 in the SBx Linecard Status
LEDs on the controller cards. The LEDs, which display the states
of the controller cards, should be solid or flashing green. If one of
the LEDs is solid amber, the corresponding controller card is not
functional. Try the next step.
 Start a local or remote management session with the switch, issue
the SHOW SYSTEM command, and examine the state of the “High
Speed Backplane” parameter. An example is shown in Figure 155.
If the parameter displays “Yes,” the backplane in the chassis
supports two AT-SBx31CFC960 Controller Cards. If the parameter
displays “No,” the chassis has an old backplane and does not
support two controller cards. If you see this, contact Allied Telesis
technical support or your sales representative for assistance.

Fault Condition 6: The controller card has an onboard battery that it uses
to maintain the date and time when the chassis is powered off or reset. If
you manually set the date and time but the card loses the information after
you power off or reset the unit, you may have forgotten to remove the
battery insulator when you installed the card in the chassis. The insulator
