3 Standard Component Installations and
Upgrades
3.1 Before You Begin
Before working with your server product, pay close attention to the safety
instructions provided in this manual. See Appendix A, “Appendix A: Safety Information ”
Warning: Electrostatic discharge (ESD) and ESD protection: ESD can damage disk drives,
boards, and other parts. We recommend that you perform all procedures in this
chapter only at an ESD workstation. If one is not available, provide some ESD
protection by wearing an antistatic wrist strap attached to chassis ground (any
unpainted metal surface) on your server when handling parts.
Tools and Supplies Needed
• #1 and #2 Phillips (cross-point) screwdrivers (or interchangeable tip screwdriver
with #1 and #2 Phillips bits)
• Personal grounding device such as an anti-static wrist strap and a grounded
conductive pad
System References
All references to left, right, front, rear, top, and bottom assume that you are facing
the front of the server, as it would be positioned for normal operation.
3.2 General Installation Procedures
The following sections present general installation and removal procedures that are
required before removing or installing internal components that are not hot-swappable
from the front or rear panels.
Removing the Chassis Covers
The NSN2U server must be operated with the top covers in place to ensure proper
cooling. You will need to remove one or both top covers to add or replace components
inside the chassis that are not hot-swappable from the front or rear panels.
CAUTION: 5V standby power is present inside the chassis whenever the power supply
module(s) are connected to a power source. Before removing either top cover, power
down the server and unplug all peripheral devices and the power cable.
A non-skid surface or a stop behind the server may be needed to prevent the server
from sliding on your work surface.
1. Observe the safety and ESD precautions in Appendix A, “Appendix A: Safety
Information”.
2. Turn off all peripheral devices connected to the server.
Turn off the server.
3. Disconnect the power cord(s).
Figure 10 shows the top covers and how they are removed.
Removing the Front Cover
1. Remove the shipping screw on the left side edge of the cover, if it is still
attached, and save it for future use.
