Handling FRUs Handling FRUs This section describes the precautions that you must take and the general procedures you must follow when removing, installing, and storing memory cards, the storage processor assembly, or any other field replaceable unit (FRU). Power Issues and AX100-Series storage systems are designed to be powered up FRUs continually. - Page 3 Handling FRUs Use the ESD kit when handling any FRU. If an emergency arises and the ESD kit is not available, follow the procedures in the Emergency Procedures (Without an ESD Kit) section. Emergency In an emergency when an ESD kit is not available, use the following Procedures (Without procedures to reduce the possibility of an electrostatic discharge by an ESD Kit)

Replacing the Memory Card Replacing the Memory Card Make sure you have an ESD wriststrap attached to your wrist as you perform the following steps. The illustrations in this section show the replacement of the SP A memory card, in an AX100SC/AX100SCi. The memory card for SP B and the procedure to remove it are identical, except that the second memory card resides to the left (from the system rear) of SP A. - Page 10 Replacing the Memory Card Replacing the Memory Card 1. Remove the replacement card from its antistatic bag. 2. Handling only the outside edges, align the new memory card with the motherboard connector. Note that the connector and card are keyed to prevent incorrect alignment. 3.
