VHDCI Cable Precautions
All of the cables to the controller, cache module, and external
cache battery (ECB) use very-high density cable interconnect
connectors (VHDCI). These connectors have extraordinarily
small mating surfaces that can be adversely affected by dust and
movement. Follow these precautions when you're connecting
VHDCI cables:
T
Clean the mating surfaces with a blast of clean air.
T
Mate the connectors by hand, then tighten the retaining
screws to 1.5 inch-pounds—approximately 1/4 additional
turn after the connectors have fully mated.
T
Test the assembly by gently pulling on the cable, which
should not produce visible separation.
Installing an HSZ70 Array Controller
Follow these instructions to replace a controller in a
single or dual-redundant configuration. See the HSZ70
Array Controller HSOF Version 7.0 Service Manual for
instructions on upgrading a subsystem to a
dual-redundant configuration.

Dual-Redundant Configurations
To remove the controller...
1.
Connect a local terminal to the operational controller. The
controller to which you're connected is "this controller;" the
controller that you're removing is the "other controller."
2.
Disable failover and take the controllers out of their dual-
5
redundant configuration with the following command:
SET NOFAILOVER
3.
Start FRUTIL, the field-replacement utility, with the
following command:
13
RUN FRUTIL
4.
Choose option 1 from the FRUTIL Main Menu to go to the
Removal Options menu.
5.
Choose option 2 from the Removal Options menu to remove
the "other controller."
6.
Confirm that you want to remove the "other controller."
7.
Wait for FRUTIL to quiesce the ports.
8.
Remove the trilink connector from the "other controller" but
don't disconnect the bus cables from the trilink connector.
9.
Disengage the two retaining levers and remove the "other
controller."
10. Remove the "other controller's" ESD cover and program
card. Save these for the new controller.
To install the new controller...
1.
Indicate to FRUTIL that you're ready to insert the new
controller.
2.
Ensure that the program card is not in the new controller and
insert the new controller into its slot. Engage its retaining
levers.
3.
Wait for FRUTIL to terminate, then connect the trilink
connector to the new controller.
4.
Restart the new controller with the following command:
RESTART OTHER_CONTROLLER
