•
For dual ECBs:
a.
Connect the replacement ECB to the open end of the ECB Y-cable
attached to the old ECB and then quickly disconnect the Y-cable from the
old ECB.
b.
Place the replacement dual ECB in a temporary location.
5. Press Enter/Return.

The ECB expiration date and deep discharge history are updated.

FRUTIL exits.
6. For a dual-redundant controller configuration with a dual ECB installed:
a.
If the “other controller” cache module is also to be connected to the
replacement ECB, connect the PC or terminal to the “other controller”
maintenance port.
The connected controller now becomes “this controller.”
b.
c.
Remove the old dual ECB and place the replacement ECB in that location.
7. Disconnect the PC or terminal from the controller maintenance port.
Replacing an ECB With the BA370 Subsystem Powered Off
Use the following steps to replace the ECB with the BA370 subsystem powered off.
1. If the controller and cache module are not operating, go to step 4. Otherwise,
proceed to step 2.
2. Connect a PC or terminal to the maintenance port of the operational controller.
The controller connected to the PC or terminal becomes “this controller”; a
second controller becomes the “other controller.”
3. Shut down the controllers.
•
In single-controller configurations, shut down “this controller” with the
following command:
SHUTDOWN THIS_CONTROLLER
