Chassis Configuration and Function
The 4D33942G01 provides the physical structure for an Ovation controller assembly. Its chassis arrangement accommodates two controller sets, allowing the system to use a dual-controller configuration.
Furthermore, the hinged design provides access to the installed controller hardware during inspection and maintenance. The chassis forms part of the controller installation rather than functioning as an independent processing module.
Controller Arrangement
The documented dual-controller configuration includes the following hardware:
- 2 processor cards
- 2 network interface cards (NICs)
- 2 I/O interface cards (IOICs)
- 2 fans
Therefore, the 4D33942G01 should be identified by its dual-controller chassis configuration when checking replacement requirements. The actual installed card types and system configuration should also be verified before ordering.
Frequently Asked Questions
Q: What is the difference between 4D33942G01 and 4D33942G02?
A: The 4D33942G01 is the hinged chassis for a dual-controller configuration. The 4D33942G02 is listed for a single-controller configuration. They should not be treated as interchangeable without checking the system design.
Q: Does the 4D33942G01 include controller cards?
A: The part number identifies the chassis assembly. The documented dual-controller arrangement specifies separate processor, NIC, and IOIC cards, as well as fans. Confirm the actual supplied assembly contents before purchase.
