IBM IBM 2212-40H, Installation And Initial Configuration Manual

Page: 19 / 90

Reset the 2212 by following the procedure in “Resetting the IBM 2212” on
page A-28. More information about the reset button is also available in “Reset
Button” on page 2-3.
If the box still does not boot, and if you have answered no to every question in
this list, contact your service representative.
Reset Button
You can use the reset button on the 2212 system card to reset the operational
software; however, it must be pressed and held for
at least 6 seconds. Otherwise,
if the reset button is pressed and held less than 6 seconds, the memory contents
will be dumped if dumping has been enabled via talk 6 in the command-line
interface. It will also reboot the 2212 if reboot has been enabled via talk 6 in the
command-line interface. If reboot has
not been enabled, the 2212 will hang until it
has been powered off and on. It is recommended that reboot always be enabled on
the 2212.
LED Indicators
The IBM 2212 has a number of light-emitting diodes (LEDs) that indicate how the
unit is functioning. The following sections describe what each LED indicates.
System Card LEDs
The PCI Mezzanine Card (PMC) adapter slot, each integrated WAN port, and the
service port on the system card have their own set of green and yellow LEDs.
Additionally, the system card has a green and yellow LED for overall system card
status.
During a power-on reset (POR), the green and yellow system card status and
service port LEDs turn on and blink in different combinations to reflect the
component that is being loaded and tested. Once the IBM 2212 has been loaded
and tested successfully, the system status card green LED is lit to indicate that the
device is operational
2 . The sections that follow reflect problems that can occur after
successful load and test.
For more information about problems that can occur before or during operational
code load, see page 2-1.
2 A simple configuration will load within 1.5 minutes. More complex configurations or those including APPN will take longer.
