Servicing the System (basic knowledge)
A Warning and Cautions
Before Top Cover or Module Removal
Before removing the top cover or system modules, follow all safety guidelines given below.
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 electrostatic discharge (ESD) protection by wearing an antistatic wrist strap
attached to chassis ground of the system—any unpainted metal surface—when handling
components.
CAUTION
The NovaScale 4020 Server exceeds the 240 VA energy hazard limits
that define an operator-accessible area. As a result, only qualified
technical individuals should access the processor, memory, and non-hot-
swap areas while the system is energized.
NOTE
When replacing hot-swap components, it is not necessary to turn off all
peripheral devices, power down the server, or unplug the AC power
cords. It is necessary to provide ESD protection. See the instructions for
the specific hot-swap component for any other safety guidelines.
