D20EME
The D20 Ethernet/Memory Expansion (EME) kit can be installed in a D20 or D200
to add expanded (Global) memory and/or Ethernet capability.
D20EME kits are offered in a variety of options to address common requirements for
D20 and D200 systems, including:
•
Ethernet
only
systems
•
Expanded (or Global) memory
only
applications
•
Combined Ethernet
and
Global memory systems
Applications of
the D20EME
The D20EME kit can be used in two main applications:
•
New installations
•
Upgrade or replacement applications.
Upgrades and
Replacements
•
When upgrading a D20 VME or D200 from a GreenSpring Ethernet card to an
Ethernet EME card, you need to re-install software into the D20ME/ME II
processor.
•
Upgrading a D200 to use a memory-only EME does not require new firmware,
but may require a new configuration.
•
If you are adding Ethernet capability to an existing D20 VME, first verify that
the D20’s power supply is capable of handling the additional load. For further
advice, contact GE for assistance.
•
The interconnect cable that links the EME main board to the MIC card
must
be
routed
inside
the D20 or D200 chassis. Routing the cable outside the chassis may
cause excessive EMI radiation and/or interfere with operation.
