CTP2024 Platform

The Juniper Networks CTP2024 Circuit to Packet platform can have up to three removable interface modules and one removable processor module, and is available in both AC-powered and DC-powered versions. It has a removable fan tray, and airflow is side-to-side. See Figure 1, Figure 2, and Figure 3.

The front panel comprises the following components (see Figure 1):

  • Interface modules.
  • Processor module—Two slots are available on this module for an optional fiber Gigabit Ethernet or Fast Ethernet PMC module. The primary SC connector is on the left side.
  • Console port—This connector is not used by the CTP device.
  • Power supply extractor—Push the button to eject the power supply module.
  • Fan tray and air filter.

The rear panel comprises the following components (See Figure 2 and Figure 3):

  • PMC I/O—Both I/Os are currently not supported.
  • Interface modules.
  • Clock module.
  • Power supply—Use a standard IEC power cord for the AC version. Use a 22-AWG fork terminal connector for the DC version. Power redundancy is supported for the DC version.

    There are no power switches on CTP2000 Series DC models, so a readily accessible disconnect device must be provided as part of the electrical installation of the unit. We recommend 22-AWG wire for DC power terminals.

  • Ethernet connection—Provides the 100-Mbps Ethernet connection to the IP network by means of a local Ethernet switch or router.
  • Console connection—Provides an asynchronous TTY connection for locally configuring the CTP device. COM3 is not supported.
  • USB port.
