Installation guide

If you will use an XMI adapter for the VAXcluster, go to Section 4.3.
You must set the VAXcluster node address when connecting to a CI. In
addition, you can modify the following module functions:
Boot time
Disable arbitration
Extend header
Alter DELTA time
Cluster size
Extend ACK timeout
The general procedure for installing jumpers is as follows:
1. Open the rear cabinet door.
2. Find the VAXBI backplane slot corresponding to the CIBCA controller
module (T1045). The two CIBCA modules occupy adjacent slots. The
controller module is the leftmost module as seen from the rear.
3. Insert jumpers between backplane pins to set the desired parameters.
4. Close the cabinet door.
A system with no jumpers installed would be configured in the following
way:
CI Node Address = 0
Boot Time = 1500 seconds
Normal CI Arbitration
Normal Header
Quiet Slot DELTA Time = 7
Cluster Size = 16
Short ACK Timeout
CAUTION: Check cluster parameters. If any system in the cluster has Quiet
Slot DELTA Time of 10 (such as a system with a CIXCD adapter), you must
change this CIBCA’s Quiet Slot DELTA Time to 10. Failure to do so may
result in unreliable operation.
