  • Page 33: Power

    SCP-PCS718-020-04H Power OWER The COTS uses –48 V dc CO battery. This voltage must be fused on a fuse panel in the CO. The fuse rating depends on the powering option used. OUNTING Attach the shelf to the selected position in the 19-inch or 23-inch equipment frames. For 23-inch frame installations, reverse the mounting brackets on the shelf.

  • Page 34: Power Connections

    Connections SCP-PCS718-020-04H Two Frame Ground termination points are provided on the COTS. The J22 and TB1 FGND Frame Ground termination points are electrically equivalent. To ground the COTS, perform one of the following ground connection options: • J22 Connection The preferred termination point is at J22, located on the lower left corner of the COTS backplane. This ground lug will accept wire in the range of 6 to 12 AWG.
