Connect the PTX10008 to External Devices

You can manage the PTX10008 router by using the two management ports on the Routing and Control Board (RCB) for out-of-band management or through the console port on the RCB. To connect a PTX10008 router to external management devices, read the following sections.

Connect a PTX10008 Router to a Network for Out-of-Band Management

You can monitor and manage a PTX10008 router using a dedicated management channel. Each PTX10008 Routing and Control Board (RCB) has two management ports: a 10/100/1000BASE-T RJ-45 port for copper connections and a 1-Gigabit SFP port for fiber connections. Use the management ports to connect the RCB to a network for out-of-band management.

Note:

You cannot use the management ports to perform the initial configuration of the PTX10008. You must configure the management ports before you can successfully connect to the PTX10008 using these ports. See Perform the Initial Configuration for the PTX10008 Router.

To connect a PTX10008 to a network for out-of-band management (see Figure 1):

  1. Connect one end of the cable to one of the two management ports (labeled MGMT) on one of the RCBs.
  2. Connect the other end of the cable to the management router.

Connect a PTX10008 Router to a Management Console

Ensure that you have an RJ-45 to DB-9 rollover cable available. An RJ-45 cable with an RJ-45 to DB-9 adapter is provided with the device.

Note:

If your laptop or PC does not have a DB-9 plug connector pin and you want to connect your laptop or PC directly to the PTX10008 router, use a combination of the RJ-45 cable and RJ-45 to DB-9 adapter supplied with the device and a USB to DB-9 plug adapter. You must provide the USB to DB-9 plug adapter.

The PTX10008 router has a console port with an RJ-45 connector. Use the console port to connect the device to a management console or to a console server.

To connect the PTX10008 router to a management console (see Figure 2 and Figure 3):

  1. Connect one end of the Ethernet cable to the console port (labeled CON).
  2. Connect the other end of the Ethernet cable into the console server (see Figure 2) or management console (see Figure 3).

Connect the Router to External Clocking and Timing Devices

The router supports external clock synchronization for Synchronous Ethernet and external inputs.

Connect the Router to a 1PPS and 10MHz Timing Device

The routing and control boards installed in the router has GPS clock ports that you can use to connect the router to a 1PPS and 10MHz timing device. Table 1 describes the GPS clock ports on the router.

You can configure the router as a timing primary device or a client device. If you configure the router as a timing primary device, the router receives inputs from the timing device through the input ports and sends outputs to a client device through the output ports. If you configure the router as a timing client device, the router receives inputs from the timing device through the input ports.

Before you connect the router to a 1PPS and 10MHz timing device, ensure that you have two cables that meet the specifications in Table 2.

To connect the router to a 1PPS and 10MHz timing device:

  1. Connect one end of the cables to the input ports on the router.

    If the router is a timing primary device, connect the router to a client device by using the output ports.

    Note:

    Ensure that the timing device supports an input or output impedance of 50 ohms, and supports input and output voltage levels that comply with ITU G.703. The timing device inputs must be 5V tolerant.

  2. Connect the other end of the cables to the 1PPS and 10MHz connectors on the timing device.

Connect the Router to a Time-of-Day Device

The JNP10K-RE1, JNP10K-RE1-E, JNP10K-RE1-LT, and JNP10K-RE1-ELT routing and control boards installed in the router have a time-of-day (ToD) port labeled ToD. You can use that port to connect the router to a ToD timing device.

Before you connect the router to a ToD timing device, ensure that you have an ESD grounding strap and a cable that meets the specifications in Table 3.

To connect the router to a ToD timing device:

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other end of the strap to one of the ESD points on the chassis.
  2. Plug one end of the RJ-45 cable into the ToD port.
  3. Plug the other end of the RJ-45 cable into the ToD timing device.
  4. Configure the port.

Connect the Router to a BITS External Clocking Device

The JNP10K-RE1, JNP10K-RE1-E, JNP10K-RE1-LT, and JNP10K-RE1-ELT routing and control boards installed in the router have two building-integrated timing supply (BITS) ports labeled BITS-0 and BITS-1. You can use them to connect the router to a BITS timing device.

Before you connect the router to a BITS timing device, ensure that you have an ESD grounding strap and a cable that meets the specifications in Table 5.
