Label Color Function
HOT-SWAP
Blue
Indicates that the board can be extracted from the chassis.
When a board is inserted into a system, the LED is lit
automatically until the hardware connection process is
completed
The LED then remains off until the extraction is once again
enabled when opening the extractors
There are two recessed pushbutton switches on the front-panel of the SC:
WARNING
DO NOT use these pushbuttons to shutdown or reset the Sun™ Solaris™
operating system. Doing so can cause file corruption and loss of system
serviceability. Use the correct shutdown procedure described in Shutdown
Procedures. These pushbuttons are for use by Avaya Technical Support
personnel only.
ABORT - Pressing the ABORT pushbutton halts the normal
operation of the SC software back to the “OK Prompt” of the
OpenBoot monitor, thereby re-initializing internal programming.
RESET - When the RESET pushbutton switch is pressed, it
generates a Power-On-Reset (POR) signal.
2.5.3 SA Synchronization and Alarm RTM
The SA alarm rear termination modules (SA/RTMs) provide the chassis management
capabilities for the SC boards, by controlling the fans operation, monitoring the correct
operation of the power supply modules, monitoring the midplane voltages, controlling
the chassis LEDs and Telco alarm relays. It functions as an I/O extension of the SC
functionality and it interconnects with all of the chassis elements. Each SA board is
hot swappable, allowing replacement during maintenance operation. In addition to the
console port on the SB board itself, the SA/RTM provides an RS-232 console serial
port for interconnection with the SC board. The terminal block connector connects
external electrical connections for triggering external devices according to Critical,
Major, and Minor alarms.
The following list summarizes the SA functionality:
„
Monitoring all midplane voltages
„
Monitoring correct operation of all power supplies
„
Controlling chassis temperature by changing fans’ speed
