Cabinet Requirements
2-2 Express5800/320Fc: Site Planning Guide
• To prevent stray voltages, all components are grounded together through the
vertical mounting rails to the cabinet frame, and then to local building ground. To
ensure signal quality, use a grounding cable provided by NEC Corporation of America
for local building ground.
• There is a plan for maintaining cables and wires to the cabinet by either running
them under the floor or placing them overhead in an overhead cable tray.
• Air flows through the cabinet from front to back.
• Filler panels cover any unused rack space to prevent air recirculation.
• Vents are evenly distributed on the front and rear doors and comprise at least 63%
of the surface area.
NOTE
If your cabinet does not have vented front and rear doors,
you can remove the doors from the cabinet while your
Express5800/320
Fc system is
operating.
Figure 2-1 shows the required rail clearance between the front vertical rails and the
inside edge of an accessory leg.
