Preventing Electrostatic Discharge Damage to the SRX1400 Services Gateway
Copyright © 2011, Juniper Networks, Inc.
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:
Always use an ESD wrist strap or ankle strap, and verify that it is in direct contact with
your skin.
CAUTION: For safety, periodically check the resistance value of the ESD
strap. The measurement should be in the range of 1 to 10 megaohms.
When handling any component that is removed from the chassis, verify that the
equipment end of your ESD strap is attached to the ESD point on the chassis, which
are shown in Figure 53 on page 149.

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 (see Figure 54
on page 150). If you are returning a component, place it in an electrostatic bag before
packing it.
