  • Low profile ( only 2U high

  • Activity and status LEDs on each card
  • V.54 loops available with certain cards
  • Variety of plug-in AC or DC power supplies available

POWER SUPPLIES

  • A number of plug-in AC or DC power supplies are available for CMN-16, to support the different power requirements of the rack. In addition, a standalone power supply is available to support one or two full racks including any type of card.
  • CMN-16 is equipped with a single plug-in power supply, and optionally, can accommodate an additional independent plug-in power supply for redundancy (see Ordering). The power supplies operate in hot standby, allowing one to be removed while the rack is in use. All modem cards and power supplies are field replaceable. AC and DC power supplies can be mixed in the same rack for redundancy.
  • The power supplies for CMN-16 can be selected according to the power requirements of the cards installed in the rack. Power supplies are available for low, medium and high power consumption.
  • When selecting a power supply for the CMN-16 rack (see Ordering), calculate the power consumption of the individual cards from the CMN-PS data sheet, Table 1 (Power Supply Modules for the CMN-16 Card Cage). Tally the total power consumption for all the cards in the rack. Select the power supply whose power rating is greater than this value. (This applies to both the single and the redundant power supply.)
  • The number of cards accommodated depends on the power supply. The power supply can be single-slot or dual-slot:
    • CMN-16 with a single-slot power supply can accommodate up to 16 modem cards.
    • CMN-16 with two single-slot power supplies can accommodate up to 15 modem cards.
    • CMN-16 with two dual-slot power supplies can accommodate up to 13 cards.
  • Available power supplies:

      PS-1: low power 8W, single-slot, AC power supply, powered from 115 or 230 VAC

      PS-2: low power 8W, single-slot, DC power supply, powered from -24 or -48 VDC

      PS-3: medium power 20W, dual-slot, AC power supply, powered from 115 or 230 VAC

      PS-4: medium power 35W, single-slot, DC power supply, powered from -48 VDC
