IP Line Description, Installation, and Operation
Electro-Magnetic Containment
Electro-Magnetic Containment (EMC) compliance requirements depend on
the regulations in effect for the country where the Meridian 1 or CS 1000
system is located. CISPR 22 Class B defines more stringent EMC limits than
CISPR 22 Class A requirements (that is, equipment that meets CISPR 22
Class B exceeds CISPR 22 Class A requirements and can be used globally).
The ITG-P 24-port line card and the Media Cards are approved for CISPR 22
Class A (and FCC Part 15 Class A) limits and approved to CISPR 22 Class B
limits with the following configurations:
ITG-P 24-port line card
For Small Systems, there is no limit to the number of ITG-P 24-port
line cards that can be installed on a shelf to meet CISPR 22 Class A
(and FCC Part 15 Class A) limits. However, to meet CISPR 22 Class
B limits, there is a limit of two cards for each shelf.
For Large Systems, there is no limit to the number of ITG-P 24-port
line cards that can be installed on a shelf to meet CISPR 22 Class A
(and FCC Part 15 Class A) limits and CISPR 22 Class B limits.
•Media Card
For Small Systems, there is no limit to the number of Media Cards
that can be installed on a shelf to meet CISPR 22 Class A (and FCC
Part 15 Class A) limits and CISPR 22 Class B limits. If the Media
Cards are installed in a shelf that already has ITG-P 24-port line
cards, then the ITG-P 24-port line card’s EMC requirements
supersedes the Media Card EMC requirements.
For Large Systems, there is no limit to the number of Media Cards
that can be installed on a shelf to meet CISPR 22 Class A (and FCC
Part 15 Class A) limits. To meet CISPR 22 Class B limits, there is a
limit of ten Media Cards that can be installed on one shelf. If the
Media Cards are to be installed in a shelf that already has ITG-P
24-port line cards, then the ITG-P 24-port line card’s EMC
requirements supersedes the Media Card’s EMC requirements.
