Removal Procedures
Caution Follow ESD rules when removing a system component. Use a wrist strap for grounding.
To remove a Storage/Control I/O Module in a nonredundant system, do the following.
Caution In a nonredundant system, power down the system before removing the card.
Step 1 Remove the Combined Controller that is connected to the Storage/Control I/O Module to be serviced.
Refer to the Cisco VCO/4K Card Technical Descriptionsfor information on how to remove the
Combined Controller.
Step 2 Use a 1/8-inch bladed screwdriverto loosen the captive mounting screws at the top and bottom of card.
Do not remove the screws from the cards.
Step 3 Grasp the screws at the top and bottom of the card and pull the card away from the midplane.
The card fits tightly into the midplane connectors and some force is required to pull it away from the
midplane. However, do not exert excessive force on the card to remove it.
Step 4 When the card is free of the connector, grasp the sides of the front panel and pull the card free of the
card slot.
Step 5 Grasp the card on its bottom edge as it is removed from the card rack.
Step 6 When you haveremoved the card from the slot, place it on an antistatic mat or in an antistatic envelope.
Note Donot replace the Combined Controller until the Storage/Control I/O Module is replaced.
Ifthe Storage/Control I/O Module is not replaced at the time of removal, do not replace the
Combined Controller.
To remove and replace a Storage/Control I/O Module card in a redundant system:
Step 1 If servicing an active Storage/Control I/O Module, switch the active side to standby. Refer to the
maintenance chapter in the Cisco VCO/4K System Administrator’sGuide for information about how to
switch the active side to standby.
Step 2 When the transition to standby is complete, remove and replace the Storage/Control I/O Module.
Ifyou are permanently removing the Storage/Control I/O Module from a nonredundant system, back up
the database before powering down the system and removing the module. Refer to theCisco VCO/4K
System Administrator’s Guide for information on backing up the database.
