User`s guide

Use the procedure in Table 5–4 to replace your controller module during the
controller warm swap replacement.
Note
Be sure to have the initial parameters that were set for the failed
controller available. You will need these parameters to set the initial
parameters for the new controller module.
Table 5–4 Controller Module Replacement
Step Description
1 Ground yourself to the cabinet grounding stud (refer to Figure 5–7).
2 You should replace the cache module now, if you removed it. Refer to
Section 5.15.
3 (HSJ controllers) Make sure the OCP cable is correctly plugged into side two of
the controller module (refer to Figure 5–9).
4 Slide the controller module into the shelf using its slot’s rightmost rails as
guides (refer to Figure 5–10).
5 Use a gentle up-and-down rocking motion to help seat the module into the
backplane. Press firmly on the module until it is seated. Finally, press firmly
once more to make sure the module is seated. You may need to lift up on the
module slightly to get the proper alignment.
6 Tighten the four mounting screws on the front bezel using a 3/32-inch Allen
wrench (for HSJ controllers) or a flat-head screwdriver (for HSD30 and HSZ
controllers).
7 Insert the program card that you removed from the failed controller into the
program card slot and press the card in until the eject button is even with the
edge of the card.
8 Snap the program card ESD shield into place by pressing the two plastic push
pins on each side of the shield.
9 Set the initial parameters as defined in Section 5.2.5. Since a new controller
module has no initial parameters, you must plug a maintenance terminal into
the new controller’s terminal port on the front bezel to enter them. Use the
same parameters that were defined for the failed controller you just removed.
Leave the maintenance terminal connected to the new controller.
10 (HSJ controllers) Connect the CI host port cable to the front of the controller
and tighten its captive screws.
(HSD30 controllers) Connect the trilink connector block, with DSSI host port
cables or cable and terminator still connected, to the host port connector on the
front of the controller. Tighten the screws on the trilink with a small flat-head
screwdriver.
(HSZ controllers) Connect the trilink connector block, with SCSI host port
cables or cable and terminator still connected, to the host port connector on the
front of the the new controller. Tighten the screws on the trilink with a small
flat-head screwdriver.
11 Press and hold the Reset (//) button while inserting the program card into the
program card slot and pressing the card until the eject button is even with the
edge of the card.
12 Release the Reset (//) button. The controller will initialize.
