• +5V: 4.75V-5.25V
• +12V: 12.43V-12.85V (although it should not be necessary to
field adjust, this is the only adjustable voltage on the BJJ power
board. Its output level is controlled by potentiometer R101.)
• VPP: 12.08V-12.12V
If the amber LED is lit, verify the voltages at the test jacks. If all voltages
are within the above limits, or if any of the voltages are high, replace the
power board. If any of the voltages are below the lower limits, either the
power board is at fault or one of the other intelligent boards is
overloading the supply. Replace the power board, if the problem persists
remove the intelligent boards one at a time until the voltage rises back
into range. Replace the faulty board which was overloading the supply
and put the original BJJ power board back in the controller.
Intelligent Option
Boards
The intelligent option boards (modem, data switch, and peripheral
monitor) are diagnosed by the microprocessor. If problems are detected
the option board’s amber LED is lit, otherwise the green LED is lit. If
the amber LED is lit, first reset the BJH microprocessor board and see if
the problem clears. If the problem reoccurs, replace the option board.
Replacing a
Memory
Backup Battery
The memory backup battery is located on the BJH (Intelligent
Controller) circuit pack. The battery provides power to retain system
configuration stored in memory in the event the BJH circuit pack is
removed or input power to the Galaxy SC is interrupted. Battery life is
usually about five years.
When the memory backup battery is low, the Memory Backup Battery
Low warning is active and the battery should be replaced. Perform the
following three procedures to replace the memory backup battery to
prevent loss of system configuration: backup system configuration;
replace memory backup battery, and restore system configuration.
Backup System
Configuration
Use the EasyView software to perform a backup of the system
configuration. Refer to the discussion of EasyView in Section 4 of this
manual. If you need to install EasyView for the first time, see the
Product Manual “Lineage
®
2000 EasyView Software for the Galaxy
Controller,” Select Code 193-104-105. Follow these steps to perform
the backup:
1. Log in and begin an EasyView session.
