Grounding disk shelves

About grounding connected disk shelves

For proper grounding, you must daisy-chain the disk shelves and storage appliance together with the provided braided copper cables and screws. Multiple racks should be grounded together.

Each disk shelf is shipped with a 0.25m (~6 inch) braided copper cable and an
M5 x 0.5 inch Phillips head screw. The copper cable has a hole on each end for grounding filer-to-shelf or shelf-to-shelf.

The storage appliance is shipped with a 0.75m (~19 inch) braided copper cable and an 8-32 x 0.5 inch Phillips head screw. The copper cable has a lug connector on each end for grounding filer-to-shelf or filer-to-second loop.

Note
The copper cable shipped with the storage appliance is only necessary when grounding the storage appliance to a second loop, or when grounding the storage appliance to a disk shelf farther away than 0.75m (the length of the filer-to-shelf cable).

Grounding connected disk shelves

To ground connected disk shelves to a storage appliance, complete the following steps.

Step	Action
1	Secure the lug at one end of the 0.25m braided copper cable to the threaded insert at the back of the storage appliance using the M5 x 0.5 inch screw.
2	Overlay the hole on one end of another 0.25m copper cable to the unused lug end of the copper cable connected to the storage appliance.
3	Using the provided M5 x 0.5 inch shelf screw, connect both copper cables to the threaded hole adjacent to the power supply receptacles on disk shelf 1.
4	Overlay the hole on one end of another 0.25m copper cable to the unused lug end of the copper cable connected to the preceding disk shelf.
5	Using the provided M5 x 0.5 inch shelf screw, connect both copper cables to the threaded hole adjacent to the power supply receptacles on the next disk shelf. The following illustration shows disk shelves grounded to an F700 series storage appliance. You can ground any NetApp storage appliance in the same manner.
6	Repeat Step 4 and Step 5 with the supplied braided copper cables until the storage appliance and all disk shelves are grounded together.
