Delta 4020 12 V 0.15 A case fan

This 40 mm Delta fan runs on 12 V and draws 0.15 A. It is built to fit H3C 3600, 5600 and S5500 switches. The EFB0412HHD model delivers targeted airflow for dense networking gear.

Questions about this item

How do I install the Delta 4020 fan into an H3C S5500 switch, and which orientation step is often missed?

Align the fan so the airflow arrow points toward the switch interior, then secure the four mounting screws; the step most often missed is confirming the 12 V .15 A connector clicks fully into the S5500 fan header.

What maintenance will the EFB0412HHD fan need after extended use in a 3600 or 5600 series chassis?

Plan to clean dust from the blades and intake vents every six months; if bearing noise appears or airflow drops, replace the entire EFB0412HHD unit as bearings are not serviceable.
