NFORMATION
This section provides information about host chassis/module compatibility and
creepage/clearance requirements. It also describes the compliance of the
PathBuilder S700 WAN access switch (Pathbuilder S700) with FCC and CE
regulations.
Host Chassis/Module
Compatibility and
Creepage/Clearance
Requirements
The installer of the E1 CBR and E3 UNI Module must ensure that the host
chassis and module are compatible and that the host chassis is capable of
providing adequate power to the module and any other auxiliary host apparatus.
The E1 CBR Module has the following input power requirements:
+5 vdc @ 3.6 Amps
The E3 UNI Module has the following input power requirements:
+5 vdc @ 3.0 Amps
Please contact 3Com for an up-to-date list of compatible host chassis.
In order to maintain the independent approval of this card, it must be installed
in such a way that with the exception of the connections to the host, when
other option cards are introduced which use or generate a hazardous voltage,
the minimum creepages and clearances specified in the table below are
maintained. A hazardous voltage is one which exceeds 42.2V peak AC or 60V
DC.
If you have any doubt, seek advice from a component engineer before installing
other adapters into the test equipment.
The larger distance shown in parentheses in the table above applies where the
local environment within the host is subject to conductive pollution or dry
non-conductive pollution which could become conductive due to condensation.
Failure to maintain these minimum distances would invalidate the approval.
