Abstract
In one embodiment, a method includes initiating a protection mode at a network device having a protective cover installed to filter airflow entering a network device, reducing one or more of a fan speed, processing functions, or power at the network device, exiting the protection mode upon removal of the protective cover from the network device, and increasing one or more of the fan speed, the processing functions, or the power to resume normal operation at the network device.
Claims20
A method comprising:
- initiating a protection mode at a network device having a protective cover installed to filter airflow entering the network device;
- reducing one or more of a fan speed, processing functions, or power at the network device;
- exiting said protection mode upon removal of the protective cover from the network device;
- and
- increasing said one or more of the fan speed, the processing functions, or the power to resume normal operation at the network device.

An apparatus comprising:
- a removable protective cover for installation on a face of a network device comprising a plurality of ports coupled to a plurality of cables, the cover comprising:
- a filter material defining a first opening at a first end for engagement with the cables coupled to the network device and a second opening for positioning adjacent to the face of the network device;
- wherein the protective cover filters airflow entering the face of the network device during a period of increased environmental contamination with the network device operating in a protection mode with reduced airflow.
An apparatus comprising:
- a network device having a face comprising a plurality of ports coupled to cables for transmitting power;
- a protective cover installed adjacent to the face of the network device with the cables passing through the protective cover;
- and
- a controller for reducing one or more of a fan speed, processing functions, or power at the network device with the protective cover installed;
- wherein the protective cover filters airflow entering the face of the network device during a period of increased environmental contamination.
