ESD Label
An ESD label is located on the unit cover towards the rear panel, above the grounding
terminal. See
Figure 6-22
.
The IPx Office unit is not equipped with a Electro-Static Dissipating (ESD)
wrist strap. It is the customer’s responsibility to provide the ESD wrist strap.
The ESD wrist strap should be worn while inserting, removing, or handling any card
in the system. For further information, see
Inserting a Coral Circuit Card, page 2-53
. Each
card is shipped inside an anti-static plastic bag. Cards should be kept in this bag
whenever handling is not required.
These labels warn the user to connect the static dissipating wrist strap connector to the
cage and put on the strap before handling the cards.
Ground Label
The ground label is affixed to the rear side of the unit beneath the ground terminal.
This label indicates that only the threaded rod above the label is to be used as a
grounding terminal. See
Figure 6-22
.
