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
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 protective cover comprising:
- a filter material arranged in a tubular shape defining a first opening at a first end for engagement with the plurality of cables coupled to the network device and a second opening for positioning adjacent to the face of the network device, wherein a size of the first opening is adjustable to engage with the plurality of cables;
- 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.
A protective cover comprising:
- a filter material arranged in a tubular shape with a first opening for sealing against one or more cables coupled to a network device and a second opening for positioning adjacent to a face of the network device, wherein a size of the first opening is adjustable to engage with the one or more cables;
- and
- a device for sealing the first opening against the one or more cables.
An apparatus comprising:
- a protective cover for temporarily filtering airflow entering a network device during a period of increased contamination, the protective cover including:
- a filter material arranged in a tubular shape with a first opening and a second opening, a size of the first opening being adjustable to engage with one or more cables passing through the protective cover, and the second opening being positioned adjacent a face of the network device comprising a plurality of ports coupled to the one or more cables.
