It's a lot like a switchable network PDU in If your chassis is particularly simple then it will be particularly simple to fit into a generic framework so that should make your life a lot easier here. Generally the simpler your system is the easier it will be to use in something generic, it's not going to be stretching ideas about how things should look and is more likely to have good helpers available already. --/9DWx/yDrRhgMJTb Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmCABwMACgkQJNaLcl1U h9ADpwf/VbjMaN7n+jZDxshUvMWZB1BdyohTc3svzJBpwgEZ64SKrE1c+kHOAoO/ 7tZNItEYVN+0hugBvbWoC7zBG+X+NPue5Spl8H+vnNFUYxVigAa2bEpNSWInZnXc TXdumtwjtmOMAGYBCh5Q+l+1KpzZbNADLEWQcei7+DXl0XqhvHzsJTslt07/hyIw vEBXZTEMP7U5DWYszH7NIMyBN+qbBDVDXHVmeg+JHq8YHh2oF4GwLrx3wC2EQakF KEQnQ2p/1xrKkzfcSkU0fCvgvf+pN9EvxS94rBkA2xDuer4vlx0ReA9Pll63GPAK EJ5KQnnPxUbSziNlhuIY83TVxIPyIw== =xLFC -----END PGP SIGNATURE----- --/9DWx/yDrRhgMJTb--
