Handling Static-Sensitive Devices Attention: Static electricity can damage the switch and other electronic devices. To avoid damage, keep static‐sensitive devices in their static‐protective packages until you are ready to install them. To reduce the possibility of electrostatic discharge, observe the following precautions: Limit your movement. Movement can cause static electricity to build up around you. The use of a grounding system is recommended. For example, wear an electrostatic‐discharge wrist strap, if one is available. Handle the device carefully, holding it by its edges or its frame. Do not touch solder joints, pins, or exposed printed circuitry. Do not leave the device where others can handle and damage it. While the device is still in its static‐protective package, touch it to an unpainted metal part of any unpainted metal surface on a grounded rack component in the rack in which you are installing the device, for at least 2 seconds. This drains static electricity from the package and from your body. Remove the device from its package and install it directly into the switch without setting it down. If it is necessary to set down the device, put it back into its static‐protective package. Do not place the device on a switch cover or on a metal surface. Take additional care when you handle devices during cold weather. Heating reduces indoor humidity and increases static electricity. Cabling Guidelines Make sure that all connection cables comply with the following recommendations: Make sure that the cables and cabling components comply with industry standards. Dress and affix cables to the rack to minimize the stress on the I/O connectors, ...

Important Notes Processor speed indicates the internal clock speed of the microprocessor; other factors also affect application performance. CD or DVD drive speed is the variable read rate. Actual speeds vary and are often less than the possible maximum. When referring to processor storage, real and virtual storage, or channel volume, KB stands for 1,024 bytes, MB stands for 1,048,576 bytes and GB stands for 1,073,741,824 bytes. When referring to hard disk drive capacity or communications volume, MB stands for 1,000,000 bytes and GB stands for 1,000,000,000 bytes. Total user‐accessible capacity can vary depending on operating environments. Maximum internal hard disk drive capacities assume the replacement of any standard hard disk drives and population of all hard‐disk‐drive bays with the largest currently supported drives that are available from Lenovo. Maximum memory might require replacement of the standard memory with an optional memory module. Each solid‐state memory cell has an intrinsic, finite number of write cycles that the cell can incur. Therefore, a solid‐state device has a maximum number of write cycles that it can be subjected to, expressed as total bytes written (TBW). A device that has exceeded this limit might fail to respond to system‐generated commands or might be incapable of being written to. Lenovo is not responsible for replacement of a device that has exceeded its maximum guaranteed number of program/erase cycles, as documented in the Official Published Specifications for the device. Lenovo makes no representations or warranties with respect to non‐Lenovo products. Support (if any) for the non‐Lenovo products is provided by the third party, not Lenovo. Some software might differ from its retail version (if available) and might not include user manuals or all program functionality. NE0152TO Installation Guide...
