3.3.3 System Status on Power-up
On power-up, the SDM-8400 executes hardware initialization, program decompression
and system test, which take less than one minute to complete. Follow the system status
from the console (see next section) or by watch the system status LEDs on the rear panel.
Table 3-1 shows the various states that the system status LEDs go through during a normal
NetPerformer power-up sequence after a power-on or software reset.
NOTE: Some of the stages of the power-up sequence are very brief, and may be diffi-
cult to distinguish from the others using the system status LEDs. Refer also to
“System Status LEDs” on page 4-3.
NOTE: If the PWR LED does not light up or the ST LED is red at the end of this
sequence, the unit may be faulty. Contact Technical Support for assistance
(see “Technical Support” on page 1-6). See also “Troubleshooting” on
page 5-1.
