Sun Enterprise 3500 System Reference Manual

Board Hot-Swapping Procedures

The CPU/Memory+ board and the I/O+ boards are hot-swappable under certain conditions. If the operating system detects a hardware failure in the board, the system powers down the corresponding board slot and turns off the left green status LED on the board. (There are three status LEDs on each board. See Table 9-2 for the board LED codes.)

When the left green LED is off, it is safe to remove the board.
