Page 15: Safety And Environmental Notices
A danger notice indicates the presence of a hazard that has the potential of causing death or serious personal injury. (D002) 2. Locate IBM System Storage SAN Volume Controller Safety Notices with the user publications that were provided with the SAN Volume Controller hardware.
Page 16 After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective. v Reinstall all covers correctly after you have finished servicing the unit. IBM SAN Volume Controller Hardware Maintenance Guide...
Page 17: Electrical Safety
Electrical voltage and current from power, telephone, and communication cables are hazardous. To avoid a shock hazard: v Connect power to this unit only with the IBM provided power cord. Do not use the IBM provided power cord for any other product.
Page 18: Inspecting The San Volume Controller For Unsafe Conditions
If unsafe conditions are present, determine how serious the hazards are and whether you can continue before you correct the problem. Before you start the safety inspection, make sure that the power is off, and that the power cord is disconnected. IBM SAN Volume Controller Hardware Maintenance Guide...
Page 19: External Device Check
Each device has required safety items installed to protect users and IBM service personnel from injury. This guide addresses only those items. Important: Good judgment must also be used to identify potential safety hazards due to the attachment of non-IBM features or options not covered by this inspection guide.
Page 20: Internal Device Checks
To conduct the internal device check, perform the following steps: 1. Check for any non-IBM changes that might have been made to the device. If any are present, obtain the “Non-IBM Alteration Attachment Survey,” form number R009, from the IBM branch office.
