2.8.3 INSTALLING OPTIONAL LOCKING BRACKET
Locking Bracket, P/N 128-2339 is available as an accessory to provide increased support for
severe vibration or shock environments on a fully populated rack and it is intended to be used
as such. Use of this bracket will increase the time required to remove and replace a module,
and there is a possibility the rack adapter may be scratched during the process; contact Kepco
applications engineering to be sure this bracket is the right solution.
To mount the locking bracket, refer to Figure 2-22 and proceed as follows:
1. Insert HSF power supplies into rack adapter with HSF front panel locking screws in lock
position, but not tight.
2. Verify rack adapter is secured to cabinet rail with the two upper mounting screws at (see Fig-
ure 2-22), then remove two lower mounting screws.
3. Position the locking bracket 3/4 inch from HSF front panels and hook it around HSF handles
by moving it upward and to the right.
4. Push locking bracket toward front panel of HSFs, making sure that all HSF locking screws
are protruding through corresponding holes in locking bracket. NOTE: If filler panels are
installed, the lower screws must either be removed or replaced with 6-32 flat head screws to
avoid interference between the locking bar and the pan head screws supplied with the filler
panel.
5. Tighten the lower mounting screws, making sure that locking bracket is flush with HSF front
panels.
6. Tighten HSF locking screws using 5/32" Allen wrench.
