Pentium II Processor Upgrades
Installing a higher-performance Pentium II processor increases the capabilities of the
server. This section describes the configuration guidelines that must be followed
prior to adding a processor as well as detailed procedures on removing and installing
a Pentium II processor module.
NOTE: If the DIGITAL server came with a Pentium Pro
processor module, refer to the previous section, “Pentium
Pro Processor Upgrades,” for detailed information on
upgrading to a higher-performance Pentium Pro processor
module.
Processor Module Configuration Guidelines
NOTE: Before you begin, create an SCU diskette using
Quick Launch. You must run the SCU after installing any
processor upgrade. This allows the server to recognize the
new processor configuration
There is only one Pentium II processor upgrade. You can upgrade from a single
processor configuration to a dual processor configuration.
•
Single processor modules must be installed in the primary Slot 1 socket
(Processor 1) and have a termination card installed in the second Slot 1
socket (Processor 2). The termination card must be removed prior to
installing a second processor.
•
A VRM must be installed for each processor installed in the processor
module.
•
DIGITAL recommends that dual processor configurations use processors
with identical stepping (manufacturing revision). Processors with different
stepping might not function properly. Stepping information appears during
the Power-On Self Test (POST) for each processor.
•
Use only DIGITAL-supplied Pentium II processor modules
