Preventing Electrostatic Discharge Damage to the Services Gateway

Many services gateway 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:
CAUTION: For safety, periodically check the resistance value of the ESD strap. The
measurement should be in the range of 1 to 10 Mohms.

SRX 210 Services Gateway General Safety Guidelines and Warnings
Always use an ESD wrist strap or ankle strap, and verify that it is in direct contact
with your skin.
When handling any component that is removed from the chassis, verify that the
equipment end of your ESD strap is attached to one of the ESD 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 into an electrostatic bag before packing
it.
