Cisco equip. and Gauss proximity

[roger-a]

Is there any documentation on the proximity of cisco equipment in relation to the Gauss value created by an MRI magnet?

What is the exact necessity of this document? If u are able to provide more detailed info as to why u need this document, it will be easy to provide a more precise reply.

I am guessing that there is a concern that the big huge magnet from an MRI does not materially interfere with the operation of any network devices, including Cisco routers.

The best studies available on this are generally performed by the military under the TEMPEST specifications. Suffice it to say the following:

1. an MRI is a significant source of EMI.

2. STP or fiber optic is preferred over UTP for ethernet operation.

3. EMI hardening is generally not going to be cost effective for you, so the best bet is to keep the router and other network devices as far away as possible from significant sources of EMI.
