Only trained and qualified personnel should install or replace the J-series router.
Preventing Electrostatic Discharge Damage
Many J-series router hardware components are sensitive to damage from static electricity.
Some components can be impaired by voltages as low as 30 V. You can easily generate
potentially damaging static voltages whenever you handle plastic or foam packing material or if
you move components across plastic or carpets. Observe the following guidelines to minimize
the potential for electrostatic discharge (ESD) damage, which can cause intermittent or
complete component failures:
●
Always use an ESD wrist strap or ankle strap, and make sure that it is in direct contact with
your skin.
!
DANGER:
DANGER:
For safety, periodically check the resistance value of the ESD strap. The
measurement should be in the range of 1 to 10 Mohms.
●
When handling any component that is removed from the chassis, make sure the
equipment end of your ESD strap is attached to one of the electrostatic discharge points
on the chassis.
●
Avoid contact between the component and your clothing. ESD voltages emitted from
clothing can still damage components.
●
When removing or installing a component, always place it component-side up on an
antistatic surface, in an antistatic card rack, or in an electrostatic bag. If you are returning a
component, place it in an electrostatic bag before packing it.
