CAUTION. Do not hot swap modules. Installing or removing modules into/from

the mainframe with the power on will damage the module. To avoid damage, turn

ff the power before installing or removing a module.

CAUTION. Only qualified personnel should perform the following procedures.

Ensure power is off to the unit before installing or removing modules.

CAUTION. To prevent damage to the modules, wear a grounded antistatic strap

when removing and installing modules and cables connected to modules.
