Chapter 4. Installing Options for the Model 6C4 and Model 6E4
This chapter provides instructions to help you add options to your system. Some option
removal instructions are provided, in case you need to remove one option to install
another. 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 notice.
Safety Considerations
Observe the following safety precautions anytime you work with this system unit.
In the system you are about to setup 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 ability
to have two power supplies running simultaneously in the same system unit. When
instructed to disconnect the power source, ensure that all power cables have been
unplugged.
DANGER
An electrical outlet that is not correctly wired could place hazardous voltage
on metal parts of the system unit or the devices that attach to the system unit.
It is the responsibility of the customer to ensure that the outlet is correctly
wired and grounded to prevent an electric shock.
Before installing or removing signal cables, ensure that the power cables for
the system drawer and all non hot-plug 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 unit 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.
CAUTION:
This system drawer uses 3-wire power cables and plugs for the user’s safety. Use
these power cables with properly grounded electrical outlets to avoid electrical
shock.
