5-4CHAPTER 5: POWER-ON

System Power-onThis section describes the stages of system power-on of the CoreBuilder 7000 family ATM switch.

Software Loading Apply electrical power to the system by inserting the power cord in the and Diagnostics power supply unit. The power supply indicator lights and the CoreBuilder

7000 family ATM switch automatically runs diagnostic software. This software verifies that every component in the system is fully functional before the system becomes active on the network. Diagnostics should take sixty seconds or less.

If any component fails power-on diagnostics, the system either fails to power on or it keeps faulty modules off-line. Once the system comes up, you can check to see which modules, if any, have failed diagnostics by checking the LED panels; in-depth information is available by viewing the system configuration screens on the administration console.

Indicators All interface and switching unit indicators light at the start of the power-on diagnostic sequence, then go out briefly. General activity LEDs light up as the system checks the switching and interface modules. Finally, individual port indicators go on as the system discovers active connections residing on the interface modules. The 10BaseT indicator on the interface module is on during normal function, even if there is no active 10BaseT management link.
