Abstract: A module and module guide is disclosed which facilitates user access to electronic circuits such as serial transceiver circuits without need to remove the host system housing or to power down the system. The module and module guide system permits this easy access while maintaining electromagnetic emissions below standard specifications. The module and module guide system also permits hot pluggablity of the circuit into the host system by providing discharge paths for static electricity that might have built up on the outside of the module during handling. The module has a housing with cooling vents and and an EMI shield. The module has guide grooves in the sides of the housing, and at least two connectors, one being a straddle mount connector on the host side and typically serial connectors on the remote side. The module guide has a frame with window forming members, the window for receiving the module.
