NetPerformer Hardware Installation Guide
3-32 Memotec Inc.
NOTE: You only need one power connector for normal operation. The second connector
is to connect a redundant power source. When using only one hot-swap power
source, the second slot should have a power supply slot cover.
3.9.2 System Status on Power-Up
On power-up, the SDM-9XXX Series unit executes program decompression, Signaling
Engine software load and system test, which takes less than one minute to complete. You
can follow the status of the initialization sequence from the console (see next section), or
by watching the front or rear panel LEDs.
Table 3-4
shows the various front panel LED states that occur during the NetPerformer
startup sequence (after a power-on or software reset).
NOTE: The entire startup sequence is executed within 30 seconds. Some of its stages
are brief, and may be difficult to distinguish from the rest. Refer also to “System
Status LEDs” on page 4-11.
