Invensys declared these workstations as obsolete and unrepairable. However,
PCS can support all of these workstations with parts and service. PCS maintains
an inventory of systems and parts as well as a supply chain for many more Sun
Microsystems parts.
NVRAM
Maintenance
The NVRAM is a memory module in every 51 Series processor that contains machine
specific information critical to the operation of the processor. It also
contains a Lithium battery. This battery has a finite life. If the battery
begins to fail, the processor may show errors such as slow clock, failure to
keep time, disk access errors, failure of certain software licenses and failure
to boot. Invensys recommends that each NVRAM be replaced every 5-7 years
depending upon model.
Each NVRAM is programmed with machine specific information. Some of this
information is key to enabling software licenses and operating disk drives, so
replacement with a generic NVRAM is not advisable. PCS routinely programs and
replaces NVRAM modules. PCS then tests each system for proper function.
When were your processors refurbished last? The time may be now before it's
too late!
Custom
Hard Disks
I/A Series software defines a very few types of specific SCSI and IDE hard disk
drives. The I/A Series software will only format and load these particular disk
drives. Replacements for these older drives are becoming difficult to find. PCS
offers a service which applies comparably sized hard disk drives from various
manufacturers as replacements to the original drives supported by the I/A
Series software. The replacement SCSI and IDE drives are 100% compatible with
I/A Series software.
