Installing Sync/ISDN BRI Net Modules in ASN Platforms

B-2 115370-A Rev. A

The power drawn from the host chassis combined with that required for any other

cards and accessories must be within the power rating of the host chassis.

You must install the net module so as not to impair the integrity of the network

protection from hazardous voltages used or generated internally by the host

chassis.

Clearances and Creepage Distances

The clearances and creepage distances (shown as X and Y, respectively, in

able B-2 and Figure B-1) must be maintained between the card and

• The host chassis in which it is installed

• Any adjacent cards installed in the host chassis

The exception to this rule is the edge connector, which is located in the host

chassis backplane, where no minimum distance applies.

The creepage distances apply to the normal ofﬁce environment. When the local

environment within the host chassis is subject to conductive pollution or dry

nonconductive pollution that could become conductive due to condensation, the

creepage distances shown in parentheses in T

able B-2 will apply.
