IBM 9009-41A Manual page 84

The ESD wrist strap must be connected to an unpainted metal surface until the service procedure is
completed, and if applicable, until the service access cover is replaced.
Attention:
• Attach an electrostatic discharge (ESD) wrist strap to the front ESD jack, to the rear ESD
jack, or to an unpainted metal surface of your hardware to prevent the electrostatic
discharge from damaging your hardware.
• When you use an ESD wrist strap, follow all electrical safety procedures. An ESD wrist strap
is used for static control. It does not increase or decrease your risk of receiving electric
shock when using or working on electrical equipment.
• If you do not have an ESD wrist strap, just prior to removing the product from ESD packaging
and installing or replacing hardware, touch an unpainted metal surface of the system for a
minimum of 5 seconds. If at any point in this service process you move away from the
system, it is important to again discharge yourself by touching an unpainted metal surface
for at least 5 seconds before you continue with the service process.
15. Remove the service access cover.
For a rack-mounted system, complete the following steps. Refer to Figure 52 on page 71.
Attention: Operating the system without the service access cover on for more than 10
minutes when the system power is turned on might damage the system components.
a. Release the service cover latch by pushing the release latch (A) in the direction shown.
b. Slide the cover (B) off the system unit. When the front of the service access cover clears the upper
frame ledge, lift the cover up and off the system unit.
