Section 2: INSTALLATION
The OpenComms NIC card may be ordered as a factory installed
option, or in a kit for field retrofit to existing Liebert units or as a
self-contained unit in its own enclosure.
If ordered as a factory-installed option, proceed directly to
subsection on User Connections.
As a retrofit kit, the circuit board is secured to a metal mounting
plate. The mounting plate then is attached to a flat metal surface
in a low-voltage section of the Liebert unit.
The self-contained model packages the interface card inside a
steel enclosure, for mounting external to the Liebert unit. A low-
voltage transformer is also provided.
