Installing grounding tape on rack uprights
Install grounding tape on the front faces of a rack to ensure a proper
grounding connection for all hardware parts fastened to the rack.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• You need a roll of tape identified by C-HT108-0625.
• To increase the surface area of grounding, the face of the adapter brackets
that contacts the rack has a strip of silvery grounding tape. For the
grounding strip to be effective, the mounting holes on the outward face
of the uprights must be clean, bare (unpainted) metal.
Procedure steps
1 Expose the bare metal of the outward face of both front and both rear
uprights. Remove the paint and any undercoating by using a finely
abrasive hand tool, for example, a drill with a clean wire wheel. Avoid
removing the paint on the sides of the upright.
2 Wipe the bare metal with a non-residual solvent to ensure that the metal
is clean.
3 From the container identified as Box 1, remove the roll or rolls of silvery
grounding tape. A roll is identified by C-HT108-0625.
4 Peel the backing off the adhesive side of the tape for about 15 cm (6 in.).
5 Apply the sticky side of the tape to the bottom of any upright face and
continue up to the top of the edge of the upright. Peel the backing off as
you progress. Ensure that the tape is centered on the face.
6 At the top edge of the upright, cut the tape.
7 Run a finger along the length of tape on the upright. Press hard enough
for dimples in the tape to indicate where the screw holes are located.
Avoid tearing the tape.
8 Repeat step 4 to step 7 for the remaining 3 uprights.
