Connecting the XRE200 to Power

 

Powering On an XRE200 External Routing Engine

Before you power on the external Routing Engine, ensure that:

Ensure that you have the following parts and tools available to power on the external Routing Engine:

  • An electrostatic discharge (ESD) grounding strap

  • An external management device such as a PC

  • An Ethernet cable to connect the external management device to the external Routing Engine

To power on the external Routing Engine:

  1. Attach the ESD grounding strap to your bare wrist and connect the strap to the ESD point on the chassis.
  2. Connect the external management device to the external routine engine's management (MGMT) or console (CON) port. For connecting a management device to the console port, see Connecting a Device to a Management Console by Using an RJ-45 Connector. For connecting a management device to the management port, see Connecting a Device to a Network for Out-of-Band Management.
  3. Turn on the power to the external management device.
  4. Ensure that the power supplies are fully inserted in the external Routing Engine and that each of their handles is flush against the faceplate.
  5. Ensure that the source power cord is inserted securely into the appliance inlet for each AC power supply, if applicable.
  6. Switch on the site circuit breakers, if applicable.
  7. On the external management device, monitor the startup process to ensure that the system boots properly.
Note

After you power on a power supply, wait for at least 60 seconds before you turn it off. After you power off a power supply, wait for at least 60 seconds before you turn it back on.

If the system is completely powered off when you turn on a power supply, the external Routing Engine boots as the power supply completes its startup sequence.

After you power on a power supply, it can take up to 60 seconds for status indicators such as power supply LEDs and the show chassis operational mode CLI command display to indicate that the power supply is functioning normally. Ignore any error indicators that appear during the first 60 seconds.

Interconnecting XRE200 External Routing Engines

Connect XRE200 External Routing Engines to each other in an EX8200 Virtual Chassis topology to provide external Routing Engine redundancy.

To connect an XRE200 External Routing Engine to another XRE200 External Routing Engine:

  1. Locate a cable that can be used to connect an XRE200 External Routing Engine to another XRE200 External Routing Engine. See Cables Connecting the XRE200 External Routing Engine to XRE200 External Routing Engines and EX8200 Switches.
  2. Connect one end of the cable to any Virtual Chassis port (VCP) on the XRE200 External Routing Engine. The VCPs on an XRE200 External Routing Engine include the built-in port 0 and ports 0 through 3 on any Virtual Chassis Control Interface (VCCI) module.

    If you are interconnecting two XRE200 External Routing Engines using the SFP optical transceivers, follow the instructions in Connecting a Fiber-Optic Cable for inserting the optical transceiver into the SFP port.

  3. Connect the other end of that cable to a VCP on the other external Routing Engine. See Figure 1.

Connecting AC Power to an XRE200 External Routing Engine

After you have installed an AC power supply in an XRE200 External Routing Engine, you connect the external Routing Engine to AC power.

Before you begin connecting AC power to an XRE200 External Routing Engine:

Note

Each power supply must be connected to a dedicated power source outlet to ensure power supply redundancy.

Ensure that you have the following parts and tools available:

  • Power cords appropriate for your geographical location

Caution

Mixing different types of power supplies in the same external Routing Engine is not a supported configuration.

To connect AC power to an external Routing Engine:

  1. Ensure that the power supplies are fully inserted in the external Routing Engine.
  2. Insert the coupler end of the power cord into the AC power cord inlet on the AC power supply faceplate.
  3. If the AC power source outlet has a power switch, set it to the OFF (0) position.
  4. Insert the power cord plug into an AC power source outlet.
  5. If the AC power source outlet has a power switch, set it to the ON (|) position.
  6. Verify that the Power LED on the power supply is lit and is on steadily.
  7. Repeat steps 2 through 6 for the second power supply.

Connecting DC Power to an XRE200 External Routing Engine

After you have installed a DC power supply in an XRE200 External Routing Engine, you connect the external Routing Engine to DC power.

Warning

Before performing DC power procedures, ensure that power is removed from the DC circuit. To ensure that all power is off, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.

Caution

Before you connect power to the switch, a licensed electrician must attach a cable lug to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the switch (for example, by causing a short circuit).

Caution

Mixing different types of power supplies in the same external Routing Engine is not a supported configuration.

Note

Each power supply input feed must be connected to a dedicated DC power source outlet.

Before you begin connecting DC power to an XRE200 External Routing Engine:

Ensure that you have the following parts and tools available:

  • The DC power source input.

  • Electrostatic discharge (ESD) grounding strap

  • DC power source cables (not provided) with the cable lugs (provided) attached.

  • 3/8 in. (9.5 mm) nut driver or socket wrench

  • Phillips (+) screwdriver, number 1

To connect DC power to an external Routing Engine:

  1. Verify that there is no power flowing from either external power source, so that the voltage across the leads of the DC power cables is 0 V. Ensure that there is no chance that the cable leads might become active during the procedure.
  2. Remove the clear plastic shield covering the field-wiring terminals on the power supply.
  3. Remove the screws on the field-wiring and ground terminal.
  4. Verify that a licensed electrician has attached a listed DC power cable lug to each power source cable and ground cable.Note

    You must bend the cable lug that attaches to the DC power source cable at a 90° angle in order to properly install the clear plastic shield covering.

  5. Insert the DC power and ground cable lugs into the appropriate terminals. Using a number 1 Phillips screwdriver, turn the screw on each terminal clockwise to secure the cable.
    • Insert the positive (+) source cable into the return terminal, which is labeled RTN.

    • Insert the negative (–) source cable into the input terminal, which is labeled –48V.

    • Align the ground cable with the ground terminal.

    Caution

    Ensure that each cable lug seats flush against the surface of the terminal block as you tighten the screws.

  6. Verify that the DC source power and grounding cables are correct, that they are not touching or blocking access to controller components, and that they do not drape where people could trip on them.
  7. Replace the clear plastic shield over the field-wiring terminals.
  8. If you are installing a second power supply, repeat Steps 2–7 for that power supply.
  9. Switch on the DC power source circuit breaker. Follow your site's procedures for safety and ESD.
  10. Verify that the Power LED on each power supply is lit and is on steadily.
