Before you replace a release tab, read the following important information:

vIn this procedure, the term controller refers to a controller or controller filler panel.

vMake sure that you have a size #1 or #0 Phillips screwdriver.

To replace a release tab, complete the following steps:

1.Read the safety information that begins on page xi and “Best practices guidelines” on page 6.

2.Make sure that it is safe to proceed:

vIf you are replacing the release tab on the only controller in the DS3200, make sure that the DS3200 is shut down for maintenance.

vIf you are replacing a power-supply release tab, make sure that the power supplies are providing redundant power (on both power supplies, the ac power LED and dc power LEDs are lit, and the fault LED is off). If the power supplies are not providing redundant power, resolve the redundancy problem first, or wait until the DS3200 is shut down for maintenance, before you replace the release tab.

3.Remove the controller or power supply from the DS3200 chassis. See “Removing a controller” on page 63 or “Replacing a power supply” on page 82.
