DANGER
Handling static-sensitive devices
Attention: Static electricity can damage electronic devices, including your server.
To avoid damage, keep static-sensitive devices in their static-protective packages
until you are ready to install them.
To reduce the possibility of damage from electrostatic discharge, observe the
following precautions:
v When you work on a BladeCenter unit that has an electrostatic discharge (ESD)
v Limit your movement. Movement can cause static electricity to build up around
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed circuitry.
v Do not leave the device where others can handle and damage it.
v While the device is still in its static-protective package, touch it to any unpainted
v Remove the device from its package and install it directly into the server
v Take additional care when handling devices during cold weather. Heating
v Do not extend more than one sliding device at a time.
v The maximum allowable weight for devices on slide rails is 80 kg
(176 lb.). Do not install sliding devices that exceed this weight.
v Always lower the leveling pads on the rack cabinet.
v Always install stabilizer brackets on the rack cabinet.
v Always install servers and optional devices starting from the bottom of the
rack cabinet.
v Always install the heaviest devices in the bottom of the rack cabinet.

blade servers. To work correctly, the wrist strap must have a good contact at
both ends (touching your skin at one end and firmly connected to the ESD
connector on the front or back of the BladeCenter unit).

body.)
