RFI and ESD Cautions:
In order to meet regulatory requirements for emitted radio frequency
interference (RFI) and electrostatic discharge (ESD) protection, an
extension cable must be made and installed between the VMEbus accessory
card cable connectors and the VME module RFI cover. The RFI cover is
the RFI and ESD protection for the workstation and needs to be installed
while you are operating the workstation. Peripheral device cables will then
plug into the cable connector on the RFI cover.
As Hewlett-Packard does not know what VMEbus accessory cards you
may use, you will need to have these extension cables made locally. For
example, if a VMEbus accessory card has a SCSI connector, a short
extension cable with a SCSI male connector on the accessory card end
and a SCSI female chassis connector on the other end. A connector port
must be drilled or milled into the RFI cover at a location suitable for the
extension cable. The chassis connector is installed on the RFI cover
and the accessory card connector is plugged into the VMEbus accessory
card. After putting the RFI cover back on the VME module, connect the
peripheral cables. Steps 7 through 10 show an example of how this is done.
If you elect not to install an extension cable between the VMEbus
accessory card and the RFI cover, or install the RFI cover, RFI and ESD
performance are likely to be inadequate.
For each VMEbus accessory card cable connector, make an extension

cable. Keep the extension cable length as short as possible.
