INSTALLING THE SVMi-20E
When installing a SVMi-20E card, it is important to remember that it is a single board
computer (SBC), much the same as any desktop PC and it is therefore very important not to
exceed these environmental limits. Note: Before installing this card it should be correctly
configured with the appropriate drive, number of Voice Processing Modules (VPMs), and all
other optional add on modules (Modem and/or 64MB DRAM).
When configuring the SVMi-20E for more than 16 ports it should be installed in slots 3, 4 or 5
of the main 7400 cabinet as these are 32 channel slots. When 16 or less ports are used the
SVMi-20E can be installed in any universal slot in the system.
IMPORTANT NOTE:
If one 8 port VPM module and one 4 port VPM module are used, the 8
Port VPM must be used in connector S2 which is the third position. If reversed, no VPM ports
will come into service. (See table below).
