PGD Status LED: Green indicates that good power is being provided to the SVMi-20E through theBack PlaneINSTALLING THE SVMi-20EWhen installing a SVMi-20E card, it is important to remember that it is a single boardcomputer (SBC), much the same as any desktop PC and it is therefore very important not toexceed these environmental limits. Note: Before installing this card it should be correctlyconfigured with the appropriate drive, number of Voice Processing Modules (VPMs), and allother 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 5of the main 7400 cabinet as these are 32 channel slots. When 16 or less ports are used theSVMi-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 8Port VPM must be used in connector S2 which is the third position. If reversed, no VPM portswill come into service. (See table below).Table 3.24 VPM Modules ConfigurationConfiguration Included on SBC VPM in SL2 VPM in SL3 Total Ports1 4 None None 4 Voice2 4 VPM-E None 8 Voice3 4 VPMF-E None 8 Voice Supporting 1 Fax4 4 VPM-E VPM-E 12 Voice5 4 VPM-E VPMF-E 12 Voice Supporting 1 Fax6 4 8VPMF-E None 12 Voice Supporting 1 Fax7 4 VPMF-E VPMF-E 12 Voice Supporting 2 Fax8 4 8VPMF-E VPM-E 16 Voice Supporting 1 Fax9 4 8VPMF-E VPMF-E 16 Voice Supporting 2 Fax10 4 8VPMF-E 8VPMF-E 20 Voice Supporting 2 FaxNote: The Fax DSP does not increase the available ports.
