Installing Sync/Ethernet Link Modules in BN Platforms

B-2 114948-A Rev. A

Power Requirements

The link modules are powered from the host chassis and have the power

requirements shown in T

able B-1.

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

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

You must install the link 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 T

able B-2 and Figure B-1) between the link module and

• The host chassis in which it is installed

• Any adjacent link 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.
