Connecting to a CI VMScluster
6-5
Refer to Figure 6-2 to determine which jumper corresponds to which back-
plane pin. The XMI backplane contains 29 pins that may need jumpers on
the backplane in sections D and E. The corresponding jumpers are denoted
W1 through W30, with W9 being reserved.
The module functions that can be modified by jumper placement are the
following:
•
Set CI port address (mandatory)
•
Set Quiet Slot DELTA Time to 10 (mandatory)
•
Boot time
•
Disable arbitration
•
Extend header
•
Cluster size
•
Extend ACK timeout
The general procedure for installing jumpers is as follows:
1.
Open the rear cabinet door and the I/O bulkhead door. Use a flash-
light for best visibility.
2.
Find the XMI backplane slot corresponding to the CIXCD module.
The internal cables are connected to the pins on the leftmost section of
the module as seen from the rear. The jumpers are installed on the
pins of the rightmost segment of the module.
3.
Install jumpers between backplane pins to set the desired module pa-
rameters.
4.
Close the I/O bulkhead door and the cabinet door.
