The IMACS is available in three chassis models to meet various space/capacity requirements. They are the IMACS 600 Universal Enclosure, the IMACS 800 Universal Enclosure and the IMACS 900 Universal Enclosure.
IMACS 800 Universal Enclosure
The IMACS 800 Universal Enclosure provides card slots on both the front and back of the unit for both front and rear loading. These are sometimes referred to as the “Network” and “User” sides respectively. There are nine card slots that are accessible from the front and an additional nine that are accessible from the back. Card slots are intended to accommodate specific card types and are keyed so that only those card types may be inserted in those slots. A CPU card may be inserted in either Slot C1 or C2. Two CPUs can be installed in Slots C1 and C2 simultaneously to provide CPU redundancy. All IMACS Universal Enclosure models are NEBS (TR63) approved.
The nine front card slots are allocated and shown in Figure 7 as follows:
