EPC800 – Profile
M.I. (CPXG211–0000)
This model, contained in a 19” RACK (36U), is one RM Node, including:
• 1 dual CPU module Power PC 604e @200Mhz – 2MB L2 cache / CPU
• 3 slots for additional dual CPU modules
• 4 memory slots
• Expandable Memory up to 4GB
• 1 floppy disk 1.44MB 3”1/2
• 1 LSA board: SCSI2 F/W SE port + 1 Ethernet port
• 3 Async. lines – 1 centronics port
• 1 MCA Bus with 6 free MCA slots (8 total)
• 2 open bays for disks (1”)
• 1 open bay for media (CD–ROM)

2. A second MCA bus, with 8 slots is possible (giving a total of 16 slots).

Compatibility with Earlier EPC Models
For compatibility with previous EPC models, an existing configuration can be extended with
an Escala T Series CPU cabinet and 8 additional slots.
Standard Adapters/Cables
One CBLG105–1800 serial cable is automatically generated for every drawer.
Two CBL1912 adapter cables (9 pin, 25 pin) are systematically provided with any base EPC
model.
An 8–port asynchronous board is per default generated for every CPU drawer:
M.I. (DCCG067–0000)
8–Port Async RS232 Adapter with connector box.
This board can be removed in order to save a slot. But remember that this board is often
necessary for establishing the RS232 serial network (heart beat messages) between the
nodes.
The 8–port Async board is also mandatory on a node which a modem is connected to,
when the Remote Maintenance Option is used, see page 12-1.
