Shutting Down the ETEP
ETEP Installation Guide 45
When the appliance powers up, all of the front panel LEDs illuminate (see Figure 33). The Alarm LED
illuminates briefly and the diagnostic code LED displays 88 to verify that the diagnostic display segments
are functioning. The power LED remains lit until the unit is powered off. The Power Supply LEDs
illuminate for each operational power supply.
During the boot process the ET1000A cycles through its startup tests, and the corresponding diagnostic
codes are displayed (see “Diagnostic Codes: ET0100A and ET1000A” on page 64). After the tests
execute successfully, the diagnostic code display is solidly illuminated with code 00.
NOTE
During the boot process the ET1000A discards all traffic on its data ports. Once the appliance is
operational, the default mode of operation passes all packets in the clear until you deploy security policies.

Shutting Down the ETEP
It is important that a proper system shutdown is performed prior to powering off the appliance. The
shutdown command halts all running tasks on the ETEP and prepares it for being powered off. Failure to
perform a shutdown may lead to file system corruption and potential appliance failure.
The ETEP remains in a shutdown state until the power is cycled. The shutdown state is indicated with an
operational code on the status/diagnostic display as shown in Table 17.
