Installing Synchronous Net Modules in an ASN Platform

Requirements for European Operation2 BNX Software Version <x.x> Test Part Number

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

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

You must install the net modules 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

You must maintain the clearances and creepage distances (shown as X and Y,

respectively, in Table B-2 and Figure B-1) between the net module and

• The host chassis in which it is installed

• Any adjacent net modules 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 Table B-2 will apply.
