5.3 Chassis Ventilation
The Vega 30 Router is a shallow 3RU 19” rack-mount chassis with front-to-back air cooling.
A cooling fan is mounted on the chassis rear which pulls air through the front of the unit and
exhausts it out of the rear, see Figure 21. Figure 21 shows the external chassis air flow and
air intake and exhaust holes.
5.3.1 Location in Rack
The following precautions should be observed:
1.
Do not obstruct the front air intake holes nor the rear air exhaust holes.
These are to allow the inlet of cooling air and air exhaust at the rear of the unit.
2.
Ensure that there is a minimum 50mm (2 inches) clearance at the rear of the unit. This
is
