• You do not have to turn off the storage product to install or replace a hot-swap redundant power supply, hot-swap hard disk drives, hot-swap solid-state drives, or hot-plug USB devices. However, you must turn off the storage product before performing any steps that involve installing, removing, or replacing adapter cables or non-hot-swap devices or components. • To view the LEDs on the system board and internal components, leave the storage product connected to power. • When you are finished working on the storage product, reinstall all safety shields, guards, labels, and ground wires. Handling static-sensitive devices Attention: Do not open the static-protective package that contains the new part until the defective part has been removed from the storage product and you are ready to install the new part. Static electricity, although harmless to you, can seriously damage storage product components and parts. When you handle storage product parts and components, take these precautions to avoid static-electricity damage: • Limit your movement. Movement can cause static electricity to build up around you. • The use of a grounding system is recommended. For example, it is recommended to wear an electrostatic discharge (ESD) wrist strap, if one is available. Ensure that you work in an ESD-safe area. • Always carefully handle the parts and other components (such as PCI cards, memory modules, system boards, and microprocessors) by edges or frame. Do not touch solder joints, pins, or exposed circuitry. • Do not leave the device where others can handle and possibly damage the device. • Before you replace a new part, touch the static-protective package containing the new part to an unpainted metal part of the storage product for at least two seconds. This reduces static electricity from the package and your body. • Remove the new part from the static-protective package and directly install it in the storage product without placing it on any other surface. If it is hard for you to do this in your specific situation, place the static-protective package of the new part on a smooth, level surface, and then place the new part on the static-protective package. • Do not place the part on the storage product cover or other metal surface. • Take additional care when handling devices during cold weather. Heating reduces indoor humidity and increases static electricity. System reliability guidelines To help ensure proper cooling and system reliability, strictly follow these guidelines: • Each of the drive bays has a drive or a dummy tray installed; or there is an electromagnetic interface (EMI) protective panel or EMI shield installed to protect the drive cage. • If the storage product supports hot-swap redundant power supplies, each of the power supply bay has a redundant power supply installed, or one bay has a redundant power supply installed while the other bay is covered by a shield. • Leave adequate space around the storage product to ensure that the storage product cooling system works well. Leave approximately 50 mm (2 inches) of open space around the front and rear of the storage product. Do not place objects in front of the fans. For proper cooling and airflow, install the storage product cover before you turn on the storage product. Operating the storage product with the storage product cover removed might damage storage product components. • Properly route the cables. For some options, such as PCI cards, follow the cabling instructions that come with the options in addition to the instructions in this manual. 42 Lenovo Storage N3310 User Guide and Hardware Maintenance Manual
