II. Equipment Startup
All of the instruments in the equipment rack will be connected to one or two PDUs (Power Distribution Units)
depending on configuration. They will be located at the bottom of the rack. If there are two, they will be mounted
back to back so that one would be located at the front of the cabinet and one at the back of the cabinet. If there is
only one, it will be located at the rear of the cabinet.
NOTE
Check that all line cords for the system cabinet are connected to AC power line
receptacles. Make sure the PDU (Power Distribution Unit) circuit breaker is in the
ON position. Also, make sure the monitor is turned on.
On the front of the system, turn the power switch to the ON position. The power switch will be located on a panel
on the front door of the cabinet or on the power panel near the top of the rack depending on which cabinet option is
selected. One cabinet option has a front door and one has no front door. For the remainder of this manual, when
referring to system cabinet power it refers to the power switch either on the cabinet door or the panel mounted in
the rack.
Emergency Off (EMO) button
An Emergency Off (EMO) button is provided either on the system cabinet door or mounted near the top of the rack
if the cabinet option without the door is selected. Pushing this button shuts down power to all system cabinet
equipment (computers mounted in the cabinet can bypass the EMO button). The EMO Tripped indicator light turns
on when the system has undergone an emergency shutdown. The power can only be turned back on by turning the
EMO button to release it and toggling the power switch from ON to OFF (EMO Reset), and then back to ON again.
This reset operation is the same for the EMO panel in the door or the EMO panel in the cabinet rack.
III. Maintenance
Hardware Replacement
WARNING
The information in this section is intended only for qualified service
personnel. Some of the procedures may expose you to hazardous voltages
that could result in personal injury or death. Do not attempt to perform these
procedures unless you are qualified to do so.
This section provides information on removal and installation of system cabinet components. Use this section to
replace components determined to be faulty.
Handling and cleaning precautions
CAUTION
Contamination will degrade the performance of the components. To avoid
contamination, always grasp cards by the side edges and shields. Do not
touch the connectors, the board surfaces, or components. On plugs and
receptacles, do not touch areas adjacent to the electrical contacts.
Because of high impedance areas, take care when handling or servicing to prevent possible contamination, which
could degrade performance. Take the following precautions when servicing any system component:
Do not store or operate the system in an environment where dust could settle on the components.
Use dry nitrogen gas to clean dust off the components, if necessary.
Handle cards only by the side edges and shields. Do not touch any board surfaces, components, or
connectors. Do not touch areas adjacent to electrical contacts.
