5. Repacking a Rack for Shipment
Repacking the Rack in the Enterprise Packaging
To improve air flow through the rack, install filler panels into the front of the rack and between any installed equipment. You can use the four threaded holes on the top of the rack to install a third-party cable tray.
Note - These instructions are for the original Sun Rack II filler panels. If your are installing other filler panels, refer to the instructions that came with the filler panels.
The filler panel option kit contains the filler panels as well as the Duosert M6 cage nuts, washers, and M6 screws required to install them in the rack.
After inserting a cage nut into a mounting hole, turn it 45 degrees to secure it into the hole (see Installing Filler Panels).
 | Caution - Use these Duosert cage nuts for filler panels only. Do not use these cage nuts when installing any other equipment into the rack. |
Figure 3-19 Installing Filler Panels
We do not provide cable trays for routing cables out the top of the rack cabinet. However, there are four threaded holes on the top of the rack where you can attach cable trays using M12 bolts.
| Caution - The standard packaging was designed solely for shipping an empty rack. Never install equipment in the rack while it is on this pallet, and never repack a rack in the standard packaging. If you must populate the rack prior to moving it to a new building or site, repack the rack in the enterprise packaging. |
