Juniper SRX300 Series Reference Guide

Preventing Electrostatic Discharge Damage to the SRX300 Series and
SRX550 High Memory 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:
•
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 must be in the range of 1 to 10 Mohms.
•
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
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 21 on page 130. If you are returning a
component, place it into an electrostatic bag before packing it.
