Safety: Before Top Cover Or Module Removal; Warnings And Cautions - Intel SR870BN4 - Server Platform - 0 MB RAM Product Manual

Safety: Before Top Cover or Module Removal

Before removing the top cover or system modules, observe these safety guidelines:
1. Turn off all peripheral devices connected to the system.
2. Power down the system by pressing and holding the power button on the front of the chassis for
several seconds.
3. After the server shuts down, unplug both AC power cords to remove standby power from the
server.
4. Provide some electrostatic discharge (ESD) protection by wearing an antistatic wrist strap
attached to chassis ground of the system—any unpainted metal surface—when handling
components.

Warnings and Cautions

These warnings and cautions apply whenever covers of the system are removed. Only a technically
qualified person should integrate, configure, or service the system.
WARNINGS
Power button: Shutting down the server with the power button (a
convex button) on the front of the chassis DOES NOT remove all power
from the system. To remove all power from system, you must also
unplug both AC power cords from the wall outlets or the system.
Unplugging the power cords removes the +12 Volt standby power that is
present when the server is powered down.
Hazardous conditions, power supply: Hazardous voltage, current,
and energy levels are present inside the power supply. There are no
user-serviceable parts inside the power supply; technically qualified
personnel should do servicing.
Hazardous conditions, devices, and cables: Hazardous electrical
conditions may be present on power, telephone, and communication
cables. Turn off the system and disconnect the power cords,
telecommunications systems, networks, and modems attached to the
system before opening it. Otherwise, personal injury or equipment
damage can result.
Hazardous conditions, processors and power pods: Thermal
conditions may be present in the processor/memory module. Allow all
fans to continue to run until they shut down on their own after power
has been turned off. After the fans stop, remove the power cords.
CAUTIONS
Electrostatic discharge (ESD) and ESD protection: ESD can
damage disk drives, boards, and other parts. We recommend that all
procedures in this chapter only be done at an ESD-protected workstation. If
