♦
Brownout mode (A. nnn ) This mode indicates a temporary reduction or
even absence of the AC electric power. If full power is not restored after
approximately five seconds, Brownout mode will change to Battery mode.
If the battery charge is already low and power consumption is high, the
system may skip Battery mode altogether and jump to Power Fail mode.
But, if power is fully restored before the countdown reaches zero, system
functions will return to normal and the batteries will start to recharge.
♦
Battery mode (b. nnn ) This mode starts if power has not been restored
in Brownout mode. The system warns users to save their work,
terminate their applications and log off the network. System shutdown
is initiated in this mode. If power is fully restored before the countdown
reaches zero, the system will return to normal function and recharge the
batteries, otherwise Power Fail mode begins.
♦
Power Fail mode (F. nnn ) In this mode, power has not yet been restored;
system shutdown should be in progress to prevent deep battery discharge.
Shutdown continues even if power should be restored at this late stage.
Under normal conditions, the server deals with the power failure itself by
means of the Event Manager and, when necessary, initiates system shutdown.
However, if an AC power outage occurs and persists when the Event
Manager is
not loaded, then the server is not able to initiate system
shutdown. You, or some other person who is local to the server, will need to
do it yourself while the system is in Battery mode. The precise steps you need
to take to shut down the system, after instructing network users to close their
applications and log off, will depend on the operating system you are using.
When the operating system is at the point where it is safe to switch the
machine to Standby, press and hold the S
TANDBY
button on the front panel
until the system switches off.
System Management Controller (SMC) Error Codes
This section contains SMC error codes. These codes fall into two groups, the
range 0F01-0F0F and the range 0F10-0F4F.
0F01-0F0F
These are initialisation codes for the SMC which will only appear immediately
after power-up. If the system stops and the LCD flashes one of these codes, it
means that there is a serious hardware problem with the SMC board and it
probably needs replacing. The following table defines these codes:
Error Code Error Factor
0F01 80C186EB internal H/W (general purpose register) error
0F02 80C186EB internal H/W (flag register) error
0F03 80C186EB internal H/W (timer) error
0F04 SC’s SRAM write/read test error
0F05 SC’s EPROM checksum error
0F06 SC’s FLASH checksum error
0F07 Copy from FLASH to SRAM failed
0F08 Copy from EPROM to SRAM failed
0F09 RTC’s RAM write/read test error
0F0A A/D converter’s busy bit error
0F0B SC’s FLASH is not programmed
0F0D UART1 internal loop test failed
0F0E UART2 internal loop test failed
0F0F UART1 and UART 2 internal loop test both failed
