7.2 GRANITE modules
GRANITE modules mount in the CHASSIS using pre-installed anti-vibration screws; they simply
need to be tightened when GRANITE modules are installed. If a screw is damaged, or the anti-
vibration patch wears off, it may be replaced.
NOTE:
When removing a mounting screw entirely, resistance may be felt as the screw is backed out.
Similarly, when reinstalling, there will be some resistance; be certain not to cross thread the
screw.
7.3 Orientation
The CHASSIS is designed to sit on a horizontal surface or be mounted such that the GRANITE
mounting plane is horizontal, whether sitting on a flat surface or installed in a rack system.
Although there are bumpers on the sides, the CHASSIS should not normally be placed in
operation on its side without provision to prevent tipping and falling.
7.4 Rackmount
Attach the CHASSIS to sliding extendable rails in a 48 cm (19 in) wide server rack using the
Rackmount, Slide-Rail Kit for GRANITE CHASSIS.
Recommended installation sequence:
1. Loosely mount slide rails to rack interface brackets using #8-32 screws and nuts.
2. Mount slide rails with brackets to server rack uprights using #10-32 screws and cage nuts.
3. Attach CHASSIS rackmount bracket to slide rails using #8-32 hardware.
4. Align bracket to rails and tighten screws.
5. Remove eight rubber bumpers from both sides of the CHASSIS.
6. Carefully set CHASSIS on rackmount brackets (like a shelf).
7. Install 8 #10-32 x 0.250 truss-head screws through rackmount bracket into the CHASSIS and
tighten.
Verify the CHASSIS slides in and out of rack smoothly with no interference; adjust and re-tighten
fasteners as needed.
