Replacing Both Control Modules
Use the following procedure to replace both control modules in the array:
1. Replace the secondary control module first. (As described in Replacing the Secondary Control Module on
page 25 .)
2. Use the “restart” command to make the active control module secondary.
3. Replace the control module that is now secondary (was active before the restart). (As described in Replacing
the Secondary Control Module on page 25 .)
Removing a Control Module
Before removing a control module:
• Review the information at the beginning of Replacing a Control Module on page 24 .
• Attach an electrostatic wrist strap. See "Protecting Hardware " on page 2 .
• Disconnect any serial or network cables attached to the control module. If there are open interface con-
nectors on the other control module, re-attach the network cables to the other control module to provide unin-
terrupted data access.
Caution:
Do not remove an active control module.
To remove a control module:
1. Push down on the orange release button (callout 1).
2. While holding the orange button (callout 1) down, swing the black release latch (callout 2) towards you. This
starts to eject the control module from the array. Remove the control module.
The following illustration provides an example of control module removal.
