Statement 20 CAUTION: A lithium ion battery is provided. To avoid possible explosion, do not burn the battery. Replace the battery only with the Lenovo-approved part. Recycle or discard the battery as instructed by local regulations. Products that are not assessed Typical products that are not assessed include but not limited to the following: • Storage and IT-rack components (for example, uninterruptible power supplies and current distribution systems) • Devices in IT rooms (for example, bulk storage units and network products) • Industrial low-voltage switchgear Safety inspection guide The purpose of this inspection guide is to assist you in identifying potentially unsafe conditions. As each machine was designed and built, required safety items were installed to protect users and service technicians from injury. This guide addresses only those items. You should use good judgment to identify potential safety hazards due to attachment of non-Lenovo Storage features or options not covered by this inspection guide. If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem. Consider these conditions and the safety hazards they present: • Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal electrical shock) • Explosive hazards, such as a damaged Cathode Ray Tube (CRT) monitor or a bulging capacitor • Mechanical hazards, such as loose or missing hardware To determine whether there are any potentially unsafe conditions, use the following checklist at the beginning of every service task. Begin the checks with the power off, and the power cords disconnected. Checklist: 1. Check exterior covers for damage (loose, broken, or sharp edges). 2. Power off the storage. Disconnect the power cords. 3. Check the power cord for: a. A third-wire ground connector in good condition. Use a meter to measure third-wire ground continuity for 0.1 ohm or less between the external ground pin and the frame ground. b. The power cord should be the authorized type specified for your storage. Go to: http://www.lenovo.com/serviceparts-lookup c. Insulation must not be frayed or worn. 4. Check for cracked or bulging batteries. 5. Remove the cover. 6. Check for any obvious non-Lenovo Storage alterations. Use good judgment as to the safety of any non-Lenovo Storage alterations. x Lenovo Storage N3310 User Guide and Hardware Maintenance Manual
