Caution – Please read the sections that apply to Class A equipment in the
"Regulatory Compliance Statements" at the beginning of this document. There are
several measures you can take to correct interference problems. For additional
correction details, see the FCC Class B Notice in the "Regulatory Compliance
Statements."

Upper Blower Assembly

The upper blower assembly (part number 540-3023) is no longer a part of the
Sun Enterprise 450 server; however, the procedures contained in the Ultra Enterprise
450 Server Owner's Guide and ShowMe How Multimedia application assume that this
part is present. For any procedure that involves removal of the main logic board, the
instructions say to disconnect the upper blower cable from the main logic board
before removing the board. Since your system does not include an upper blower
assembly, you can safely ignore this step.

Power Interlock

The Sun Enterprise 450 server features a power interlock safety mechanism.
Removing either of the system side panels activates the system power interlock
switches. This safety mechanism prevents DC voltages from reaching any internal
component when either side panel is removed and the AC power switch is left on.
Do not remove either side panel while the system is running. Doing so will cause the
system to power off abruptly.
