A9852A HP Superdome 12-Slot PCI-X I/O Chassis Enclosure

A9852A is the I/O chassis enclosure (ICE) for the 12-slot PCI-X chassis of the HP Integrity Superdome sx2000. An ICE holds one or two 12-slot I/O chassis, so it provides up to 24 PCI-X I/O slots, and the chassis put the I/O cards in a horizontal position.

The enclosure mounts in an HP Universal 10K G2 rack and takes 9U of rack space. All I/O chassis sit on a sliding shelf inside the ICE, which provides online addition, replacement and deletion of I/O cards and hot swap access to the I/O fans. Four N+1 I/O fans at the rear provide cooling, drawing air through the front and the I/O chassis lid on the side and exhausting out the rear. The fan assembly is hot swappable and an LED on each fan assembly indicates that the fan is operating.

The ICE and the 12-slot I/O chassis are the only I/O expansion parts that are field rackable, and only into a previously installed I/O expansion cabinet. The spare numbers include the ICE chassis enclosure A5862-04020, the sheet metal chassis tray A5862-04021, the bezel assembly A5862-62001, the I/O chassis backplane board A5862-60201, the enclosure fan A5862-04032 and the I/O cable main retractor arm with slides A5862-04024.
