CTP2000 Series Console Cable Pinouts

The console port CTP2008, CTP2024, and CTP2056 devices with the new PP833 processor uses a USB-type connector located on the right of the PP833 faceplate labelled “RS-232”. CTP2000 series devices with the PP310 and PP332 processors use an RJ-45 connected to the COM2 port. This cable must be connected during the first boot process. Use a shielded cable for the COM2 port on the CTP2056 device. Figure 1 displays the console cable pin configurations for CTP2000 series devices with the PP310 and PP332 processors. On the left is the RJ-45 connector, and on the right is the DB-9 connector with the pin numbering indicated.

The console connections are configured to the following parameters:

Speed: 9600 bps
Data bits: 8
Stop bits: 1
Flow control: Xon/Xoff
Parity: none

You can connect a console (PC, Macintosh, or UNIX workstation) directly to the COM2 port on the PP310 and PP332 processors. On the PP833 processor, a console is connected using the supplied USB-to-DB9 cable (p/n 720-071594), in which the DB-9 connector has the same pinout as a standard RS-232 DTE port. When the USB-to-DB9 cable is used in conjunction with the DB-9 adapter labelled “p/n 450-071855” (see Figure 2), the available RJ-45 console pinout will be the same as the console connection on the RTM of PP332/PP310 processor.

Alternatively, if the DB-9 adapter from the bag labelled “p/n 720-056657” (see Figure 3) is used instead of “p/n 450-071855”, the available RJ-45 console pinout will be similar to the CTP150 console port (and other Juniper routers). To connect the PP833 processor with the DB-9 plug serial port of a PC, additionally connect a straight RJ-45 cable with the DB-9 adapter from the bag labelled “p/n 720-056657”. The other end of the RJ-45 cable connects to the DB-9 adapter from the bag labelled “p/n 720-014126” (see Figure 4). Then, you can connect the PC’s DB-9 plug connector with the DB-9 adapter “p/n 720-014126”.

Upgrading from PP833 to PPF84 Processor

To upgrade from PP833 to PPF84:

Replace the PMC card in the PP8333 processor with XMC card. For more information on installing XMC card, see Installing and Removing XMC Module.

Note:

You don't need an adapter for PPF84, as it has RJ45 console port. See Figure 1.
Make sure to have CTP2000-IM-2WFXS-B with 2 PSUs when upgrading to PPF84.
