8.Place the Netfinity EXP300 into its new home, rack, Netbay or tower.

9.If internal switch 3 on the switch card of your Netfinity EXP300 is set on (split bus or dual bus mode), then ensure that the SCSI cable, if plugged into the left side of the Netfinity EXP300, is now plugged into the right side and vice versa. If internal switch 3 is off, you do not have to switch the SCSI cable.

Installing the EXP300 in a rack

The EXP300 expansion unit requires 3U (5.25 in) of Electronic Industries Association (EIA) rack-mounting space.

Important: Review the documentation that comes with your rack enclosure for safety and cabling considerations. When installing your server in a rack, the following considerations should be made:

•Install the expansion unit in a maximum 35 degree C environment.

•To ensure proper air flow, do not block the air vents; usually 15 cm (6 inches) of air space is sufficient.

Note: Because of the limited space in some racks, it might be easier to connect and route cables before you install the mounting brackets and hardware devices.

•To ensure stability, take precautions to prevent uneven loading of the rack. Loading of the rack should begin at the bottom.

•Turn off the power to your rack.

•When multiple components are installed in a rack, take precautions to prevent overloading of the power outlets.

•The expansion unit should always be connected to a properly grounded outlet.

•Refer to the rack documentation for instructions on removing the rack enclosure doors and side panels.

Use the rack-mounting template that comes with the expansion unit to locate the rack- mounting holes and install the unit in a rack cabinet. If you do not have the template, you can use the following steps to install your expansion unit:

1.Use the following illustration of the front and rear rack mounting flanges to determine the appropriate rack-mounting holes for installing cage nuts or clip nuts to secure the Netfinity EXP300 rails. From left to right, the illustration shows the front and rear flanges respectively.
