    MIX 56 User Manual SSEMBLIES Front Panel Each MIX 56 chassis houses two independent systems, System 1 and Sys- tem 2. The front of each system is equipped identically (with the exception of one electrostatic discharge (ESD) jack per chassis), and either system can be used as a DSX only, as a nonredundant multiplexer, or as a redun- dant multiplexer.
  • Page 14: Leds

    To use a system as a multiplexer with full DSX capabilities, connect incom- ing and outgoing DS1 signals to the front wire-wrap pins. LEDS The LED status indicators on the MIX 56 front panel are grouped into the following categories: •...

  • Page 24: Location And Space

    Telect recommends heat baffles below each MIX 56: for a 19-in. rack, order part # 747-9999-0019; for a 23-in. rack, order part # 747-9999-0023.
  • Page 25: Tools And Equipment

    Each configuration varies in weight depending on the number and type of chassis’ and cables used. If bay weight exceeds the floor support capacity, computer floor supports can be ordered from Telect (part # 071-6000-3001/ 3002 for one or two panels respectively).
  • Page 26: Power

    –48 Vdc at 1 amp, or 24Vdc at 2 amp. The panel must be acces- sible when operating the unit. The chassis must receive 20Vdc to 60Vdc. Since MIX 56 includes active components, Telect recommends using a dual feed panel to provide input power redundancy.
  • Page 27: Installing Mix 56

    These procedures may be modified to agree with site practices or operating company procedures. If you are installing the optional MIX 56 Broadband Sidecar (PN 747-9999-2001), read the installation instructions included with the kit before installing the MIX 56 chassis.
  • Page 28: Rack-Mounting The Chassis

    Repeat steps 2 and 3 on the other side of the chassis. Rack-Mounting the Chassis A single MIX 56 chassis requires 5.25 in. of vertical space (the height of the chassis). When installing one chassis on top of another, install a heat baffle of at least one rack unit above and below the pair.
  • Page 29 MIX 56 User Manual Step Action Loosely mount the chassis to the rack using the four #12-24 screws (included). On one side of the chassis, insert a wire management ring (includ- ed) between the chassis mounting bracket and the head of the screw, as shown below, and tighten the screws tight enough to hold the ring in place.
  • Page 30: Cabling A System

    Cabling a System The MIX 56 chassis contains two independent systems that each require cabling. Telect recommends routing cables to the side of the chassis the system is on, not crossing the cables to the other side of the chassis.
