Tools and Parts Required for Installation

 

To install the Juniper Networks EX9253 Ethernet Switch on a rack, you need:

  • Two rear mounting brackets—preinstalled

  • Eight screws to secure the switch to the rack—not provided

  • Cable management brackets and screws to attach the brackets to the chassis—provided

  • (Optional) Air filter unit—provided

  • Phillips (+) screwdriver, number 2—not provided

  • An electrostatic discharge (ESD) wrist strap with cable—provided

To connect the switch to earth ground, you need:

  • A 14 AWG ground terminal lug sized for #10 screw (Panduit LCD10-14B-L or equivalent)—provided

  • A grounding cable (minimum 14–10 AWG (2–5.3 mm²), minimum 60°C wire or as permitted by local code)—not provided

  • A pair of M5 Pan Head screws—provided

To connect AC power to the switch, you need:

  • An AC power supply installed in the switch—provided

  • An AC power cord with a plug appropriate for your geographical location—provided

  • A power cord retainer—provided

  • An external management device—not provided

To connect DC power to the switch, you need:

  • A DC power supply installed in the switch—provided

  • Two DC power source cables (minimum 10 AWG (1.3 mm²), minimum 60°C wire or as permitted by local code)—not provided

  • Two 16-14 AWG ring lugs sized for #6 screws (Panduit PN10-10R or equivalent)—provided

  • A torque-controlled socket nut driver, with a maximum torque capacity of 6 lb-in. (0.68 Nm), for tightening the screws on the terminals on each power supply—not provided

    Caution

    The maximum torque rating of the terminal screws on the DC power supply is 6 lb-in. (0.68 Nm). The terminal screws might be damaged if excessive torque is applied. Use only a torque-controlled driver to tighten screws on the DC power supply terminals. Use an appropriately sized driver, with a maximum torque capacity of 6 lb-in. (0.68 Nm) or less. Ensure that the driver is undamaged and properly calibrated and that you have been trained in its use. You may want to use a driver that is designed to prevent overtorque when the preset torque level is achieved.

  • A wire cutter—not provided

  • An external management device—not provided

To perform initial configuration of the switch, you need:

  • An Ethernet cable with an RJ-45 connector attached—provided

  • An RJ-45 to DB-9 serial port adapter—provided

  • A management host, such as a PC, with an Ethernet port—not provided
