  • Page 109 Mount the outer rails to the Scalar 218FC by placing each rail over the three studs on each side of the unit. Loosely secure the outer rails to the studs using three nylock nuts. Do not tighten the nuts completely. The following illustration shows the location of the rail-mounting studs.

    Scalar. With your assistant, lift the Scalar 218FC up and slide the slides into the rails. The slides will continue past the slide stops. It is not necessary to depress them when pushing the Scalar into the rails.

  • Page 113: Installing The Cable Channel

    Secure the power cord and SCSI cable to the cable channel using the attached cable ties. Be sure to leave enough slack in the cables to allow the Scalar 218FC to be pulled away from the rack as far as the slide stops permit. The illustration on the following page shows how the channel should be installed in your rack.
