Chapter 5. Installing Options for the pSeries 650
This chapter provides instructions to help you add options to your system. In case you need to remove
one option to install another, some option removal instructions are provided. If you have several internal
options to install, these instructions enable you to add them all at one time.
Before performing any of the installation or removal procedures in this chapter, read the following safety
considerations.
Safety Considerations
Observe the following safety precautions anytime you work with this system unit.
In the system you are about to set up or service:
v
The ac power interface connector is considered the main power disconnect device.
v
This system has redundant power supply capabilities, meaning that it has the capability of having two
power supplies running simultaneously in the same system unit. When you are instructed to disconnect
the power source, ensure that all power cords have been unplugged.
DANGER
An electrical outlet that is not correctly wired could place hazardous voltage on metal parts
of the system or the devices that attach to the system. It is the responsibility of the customer
to ensure that the outlet is correctly wired and grounded to prevent an electrical shock.
Before installing or removing signal cables, ensure that the power cables for the system unit
and all attached devices are unplugged.
When adding or removing any additional devices to or from the system, ensure that the
power cables for those devices are unplugged before the signal cables are connected. If
possible, disconnect all power cables from the existing system before you add a device.
Use one hand, when possible, to connect or disconnect signal cables to prevent a possible
shock from touching two surfaces with different electrical potentials.
During an electrical storm, do not connect cables for display stations, printers, telephones,
or station protectors for communications lines.
