System Reliability Guidelines; Handling Static-Sensitive Devices - Lenovo ThinkEdge SE350 V2 User Manual

b. Click Preconfigured Model or Configure to order.
c. Enter the machine type and model for your server to display the configurator page.
d. Click Power ➙ Power Cables to see all line cords.
• Make sure that the insulation is not frayed or worn.
3. Check for any obvious non-Lenovo alterations. Use good judgment as to the safety of any non-Lenovo
alterations.
4. Check inside the server for any obvious unsafe conditions, such as metal filings, contamination, water or
other liquid, or signs of fire or smoke damage.
5. Check for worn, frayed, or pinched cables.
6. Make sure that the power-supply cover fasteners (screws or rivets) have not been removed or tampered
with.

System reliability guidelines

Review the system reliability guidelines to ensure proper system cooling and reliability.
Make sure the following requirements are met:
• Adequate space around the server must be spared to allow server cooling system to work properly. Leave
approximately 50 mm (2.0 in.) of open space around the front and rear of the server. Do not place any
object in front of the fans.
• For proper cooling and airflow, refit the server cover before you turn the power on. Do not operate the
server for more than 30 minutes with the server cover removed, for it might damage server components.
• Cabling instructions that come with optional components must be followed.
• A failed fan must be replaced within 48 hours after malfunction.
• A removed hot-swap drive must be replaced within two minutes after removal.
• Every air baffle that comes with the server must be installed when the server starts (some servers might
come with more than one air baffle). Operating the server with a missing air baffle might damage the
processor.

Handling static-sensitive devices

Review these guidelines before you handle static-sensitive devices to reduce the possibility of damage from
electrostatic discharge.
Attention: Prevent exposure to static electricity, which might lead to system halt and loss of data, by
keeping static-sensitive components in their static-protective packages until installation, and handling these
devices with an electrostatic-discharge wrist strap or other grounding system.
• Limit your movement to prevent building up static electricity around you.
• Take additional care when handling devices during cold weather, for heating would reduce indoor
humidity and increase static electricity.
• Always use an electrostatic-discharge wrist strap or other grounding system, particularly when working
inside the server with the power on.
• While the device is still in its static-protective package, touch it to an unpainted metal surface on the
outside of the server for at least two seconds. This drains static electricity from the package and from your
body.
• Remove the device from the package and install it directly into the server without putting it down. If it is
necessary to put the device down, put it back into the static-protective package. Never place the device
on the server or on any metal surface.
