12 IBM 4769 Installation
Temperature
Do not expose the coprocessor to temperatures outside the limits in
Batteries
Do not remove battery power from the coprocessor. Data in the protected memory is lost
(zeroized) when battery power is removed, rendering the coprocessor permanently inoperable.
For information about replacing the batteries without erasing the protected memory, see
“Replacing coprocessor batteries” on page 7.
Requirements and specifications
The requirements and specification for the coprocessor consist of the necessary hardware and
software, environmental requirements, and physical characteristics.
Hardware requirement
The coprocessor must be installed in an x86 server from the list of x86 servers. See notes
below. No additional hardware or cabling is required.
Note:
The full speed USB 2.0 Micro connector is for development use only. It is not intended for
customer use.
Software requirement
The coprocessor requires support software, for example, the IBM 4769 CCA Support Program,
for both the host machine and for its internal firmware. Operating system support is determined
by the support software. This publication does not discuss the installation of support software.
