Chapter 7
Disassembly and Reassembly
This chapter contains step-by-step instructions for disassembling and reassembling all Field
Replaceable Units (FRUs) in the server system. For reassembling the system, follow the
disassembly procedures in reverse order. When you disassemble any part of the server, note the
orientation and placement of any cables or shielding that you remove.
This chapter also describes the internal optional devices available for the server, procedures for
install or removing such optional devices, and notes on using them.
IMPORTANT:
!
The server management logic on the system board monitors and logs
system voltage changes. When powering down the system you may
experience a 1–5 second delay from the time you press the push-
button power on/off switch on the front panel and the system
powering down. This is normal system operation and is required by
the server management logic.
!
Make sure to use only optional devices and cables authorized by NEC.
Repair of the server due to malfunctions, failures, or damage resulted
from installing such devices or cables will be charged.
!
When you make changes to the hardware configuration, make sure to
update the system configuration information.
