Enterasys S Series - Dust Mitigation and Prevention; Another Mitigated Non-Ideal Open Rack Configuration

Dust Mitigation and Prevention
Enterasys S-Series Stand Alone (SSA) Hardware Installation Guide E-5
Figure E-5 below shows another mitigation strategy for open racks containing sub-systems with
mixed flow direction. Mitigation of potential hot air recirculation is achieved by separating unlike
systems with products having front to back airflow patterns.

Dust Mitigation and Prevention
Dust accumulation on inlet and exit venting is not uncommon after prolonged use. In dustier
environments this accumulation can be much quicker.
Enterasys strongly recommends routine maintenance to check for clean inlet and exit vents on this
equipment. Over time, dust accumulation can create vent blockages, thereby decreasing airflow
and increasing component temperatures, resulting in reduced reliability. Recommended
maintenance should start with monthly inspections and be adjusted based on dust accumulation
levels.
Table E-1 on page E-6 notes the maximum dust and debris accumulation limits for room
environments as a reference.
