1. Remove the card using the concurrent card removal and replacement procedure
for the model or FC that you are working on (see “Chapter 4. Removal and
Installation Procedures” on page 617).
Note: If the concurrent card removal procedure fails, then power the system
down normally prior to replacing the cache battery pack. (See “Powering

Note: Save the battery casing. The replacement battery pack will not come
equipped with a casing.
