Anti-static Measures
Installing or Uninstalling Internal Optional Devices
(1) To avoid electric hazard and malfunction of the device, be sure to turn off the Power
switch of the server and unplug the power cord from outlet before starting work, except
for hot-swappable devices.
(2) The Optional Devices contains electronic components sensitive to static electricity.
Avoid failures caused by static electricity when installing or removing any optional
devices. Wear a wrist strap on your wrist and provide earthing before starting work. If
no wrist strap is available, discharge static electricity from your body by touching an
unpainted metal part of the chassis which is grounded.
(3) Handling of cables
When connecting a cable (e.g., LAN cable), static electricity may also be charged due
to friction against floor. Connecting a charged cable with an I/O device may cause
damage to the device.
It is recommended to discharge static electricity before connecting a cable by using
ionizer or the like. Consult with your sales representative for apparatus to discharge
static electricity.
