Unistruts
Steps
To attach the unistruts to the chassis, perform the following steps:
SUMMARY STEPS
1.
Attach each unistrut to the top of the chassis by inserting four M12 hex head bolts and washers, two for
each strut, into the bolt holes on the inside of the strut, and tightening with the 8mm hex bit socket and

DETAILED STEPS
Attach each unistrut to the top of the chassis by inserting four M12 hex head bolts and washers, two for each strut, into
the bolt holes on the inside of the strut, and tightening with the 8mm hex bit socket and ratchet wrench. The closed end
of a unistrut faces the front (PLIM) side of the chassis. See
Figure 10: Attaching the Unistrut, on page 18
.
The left unistrut (as you face the front [PLIM] side of the chassis) has a cutaway in the rear to admit the chassis
ground cable; the right unistrut does not. The right unistrut as viewed from the front PLIM side of the router
has a bolt position that is 6.5 inches from the end at the rear of the router.
