4. Attach the false front panel (provided with rack shelf part

#60-190-01) to the unoccupied side of the rack (as shown

above), or install a second half-rack-width device in that

side by repeating steps 1 through 3.

5. Attach the rack shelf to the rack using four 10-32 x ¾" bolts

(provided). Insert the bolts through #10 beveled washers,

then through the holes in the rack, as shown above.

Rack mounting ventilation recommendations

Excessive heat can decrease the optimal lifetime of the power

ampliﬁer. An over temp indicator LED on the front panel of

the ampliﬁer lights red whenever the recommended operating

temperature has been exceeded (see "Front Panel Features and

Operation" in chapter 3).

To reduce the chances for an over temp condition, the XPA(s)

should be arranged in a rack environment so that adequate

airow is available both above and below the XPA whenever

possible. No more than two XPAs should be arranged one-

on-top-of-the-other in a rack without an open space between

them, as shown in the following illustration. An XPA can also

be arranged above or below another non-XPA device, but there

must be an open space both above and below those devices.
