be used to remove the cable from the controller without potentially damaging the cable
(see Figure 3–4).
a. Disconnect all host bus cables from the controller.
b. Disengage both retaining levers and remove the controller from the enclosure.
c. Place the controller in an antistatic bag or on a grounded antistatic mat.
10. Disengage both retaining levers and partially remove the "other controller" cache
module—about halfway.

a. Disconnect the ECB Y-cable from the "other controller" cache module.
b. Remove the cache module from the enclosure.

13. Is a replacement controller and cache module available now?
• No. Enter N(o) and disconnect the PC or terminal from the controller
maintenance port.
FRUTIL exits.
NOTE: If reverting to a single-controller configuration, fill the vacant controller and
cache module bays with blank bezels to prevent the enclosure from developing a
potential over-temperature condition.
• Yes. Use the following steps to remove the DIMMs from the cache module for
installation in the replacement cache module.
a. Press down on the DIMM retaining clips 3 at both ends of the DIMM 1
being removed (see Figure 3–6).
NOTE: To make pressing down on the DIMM retaining clips easier, use the eraser end
of a pencil or a small screwdriver.
