Jumper Setting
==============

J9 and J10 Terminators
-----------------------
All single-drive systems have terminators J9 and J10 installed. For
multi-drive systems, terminators J9 and J10 may only installed in the
last drive of a daisychain configuration. All drives are shipped with
the terminators installed.

J18 Grounding Connector
------------------------
The frame grounding connector (J18) is a Faston AMP P/N 61761-2 tap
connector. The recommended mating connector is AMP P/N 62187-1 or
equivalent. The hole in the Faston tap accomodates a wire size of
18 AWG.

Use of frame ground connection is recommended in order to reduce
ground loops which may result in electrical noise problems.
