Use the following steps in "Removing a GLM" and "Installing a
GLM" to replace a GLM.
Removing a GLM
Use the following steps to remove a GLM:
1. Connect a PC or terminal to the operational controller. The
controller to which you're connected is "this controller"; the
controller whose GLM you are replacing is the "other
controller."
2. Disable failover with the following command:
SET NOFAILOVER
3. Start FRUTIL with the following command:
RUN FRUTIL
FRUTIL displays the following:
Do you intend to replace this controller's cache
battery? Y/N
4. Enter N(o). FRUTIL displays the FRUTIL Main menu:

7. Enter Y(es) and press return. FRUTIL displays the
following:
Quiescing all device ports.
Device Port 1 quiesced.
Device Port 2 quiesced.
Device Port 3 quiesced.
Device Port 4 quiesced.
Device Port 5 quiesced.
Device Port 6 quiesced.
All device ports quiesced.

Figure 3. Location of Controllers and Cache Module
CAUTION: The device ports must quiesce before removing the
cache module. Failure to allow the ports to quiesce may result
in data loss. Quiescing may take several minutes.
ESD can easily damage a controller or GLM. Wear a snug-fitting,
grounded ESD wrist strap.
NOTE: A countdown timer allows a total of two minutes to
remove the cache module. If you exceed two minutes, "this
controller" will exit FRUTIL and resume operations. If this
happens, go back to step 3.
8. Remove the program card's ESD cover and program card.
Save them for reinstallation later.
9. Disconnect the host bus cables from the "other controller"
using needle nose pliers (see Figure 2).
NOTE: One or two host bus cables may be attached, depending
on the configuration.
