Replacing an ECB With Cabinet Powered On
Use the following steps to replace the ECB with the cabinet powered on:
NOTE: The procedure for a dual-redundant controller configuration assumes that a single ECB
with a dual battery is installed and an empty bay is available for the replacement ECB. If an
empty bay is not available, place the new ECB on the top of the enclosure. After removing the
old ECB, carefully insert the new ECB into the empty bay.
1. Connect a PC or terminal to the maintenance port of the controller with the ECB that
needs replacement.
The controller connected to becomes “this controller;” the controller for the ECB
cache module becomes the “other controller.”
2. Start FRUTIL with the following command:
