Installing and Connecting an EX9253 Switch

The EX9253 switch chassis is a rigid sheet-metal structure that houses the other hardware components such as Routing Engine, line cards, power supplies, fan trays, and air filter.

To install and connect an EX9253 switch:

  1. Follow instructions in Unpacking an EX9253 Switch.
  2. Mount the switch by following instructions in Mounting an EX9253 Switch on a Rack or Cabinet.
  3. Connect earth ground to the switch by following instructions in Connecting Earth Ground to an EX9253 Switch.
  4. Follow instructions for connecting power as appropriate for your site:

  5. Perform initial configuration of the switch by following instructions in Connecting and Configuring an EX9253 Switch.
  6. Set the switch’ s management options by following the appropriate instructions:

Mounting an EX9253 Switch on a Rack or Cabinet

You can mount an EX9253 switch on four posts of a 19-in. (450 mm) rack as defined by the Electronic Components Industry Association (http://www.ecianow.org) by using the mounting brackets provided with the switch.

The remainder of this topic uses rack to mean rack or cabinet.

Before mounting the switch:

Warning

Ensure that you understand how to prevent ESD damage (see Prevention of Electrostatic Discharge Damage).

Caution

Have a qualified technician verify that the rack is strong enough to support the switch’s weight.

Ensure that the rack is in its permanent location, allowing adequate clearance for airflow and maintenance, and secured to the building structure.

If you are mounting multiple switches on a rack, mount a switch in the bottom of the rack first and proceed to mount the rest of the switches from bottom to top.

Note

The weight of an AC-powered chassis fully loaded with all FRUs is 157.4 lb (71.4 kg) and the weight of a DC-powered chassis fully loaded with all FRUs is 163.4 lb (74.11 kg). You must use material-handling systems (such as levers, slings, lifts, and so on) to lift any equipment that weighs above 121.2 lb (55 kg). When this is not practical, you must use specially trained persons (such as riggers or movers) to lift the switch. Mounting an EX9253 switch requires one person to guide the switch in place and a second person to install the mounting screws to secure the switch to the rack if you are using material-handling systems or two people to lift the switch and a third person to install the mounting screws to secure the switch to the rack if you are using specially trained persons.

We recommend that you install cover panels in the unused slots.

Ensure that you have the following parts and tools available:

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

  • Two rear mounting brackets—preinstalled

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

  • Air filter unit—provided

  • Cover panels for empty slots

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

To mount the switch on a rack:

  1. Position the switch in front of the rack.
  2. Wrap and fasten one end of an ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the switch.Note

    The rear mounting brackets on either side of the chassis are movable; you can adjust the brackets according to the depth of the rack. However, the front mounting brackets on either side of the chassis are fixed to the chassis.

  3. Remove the screw on either side of the chassis that holds the rear mounting brackets by using a Phillips (+), number 2 screwdriver, and slide the brackets out of the chassis (see Figure 1). Save the brackets.
    Figure 1: Removing the Rear Mounting Brackets

the Rear Mounting Brackets
  4. Position the cable management brackets on each side of the front of the chassis. Attach the brackets to the chassis by using the screws provided with the brackets (see Figure 2).
    Figure 2: Installing the Cable Management Brackets

the Cable Management Brackets
  5. Lift the switch by using material-handling systems (such as levers, slings, lifts, and so on). If that is not practical, have a specially trained person hold on to the bottom of the chassis on each side and carefully lift it. The front mounting brackets must contact the rack rails and the holes on the front mounting brackets must align with the threaded holes on the rack. Align the bottom hole in each front mounting bracket with a hole in each post of the rack, making sure that the chassis is level.
  6. Have another person secure the switch to the rack by inserting the screws appropriate for your rack through the holes in the bracket and the threaded holes on the rack (see Figure 3). Tighten the screws.
    Figure 3: Inserting the Screws Through the Front Mounting Brackets
    Inserting the Screws Through the Front Mounting Brackets
  7. On the rear of the chassis, slide the rear mounting brackets on either side of the chassis until the rear mounting brackets contact the rack rails (see Figure 4).
    Figure 4: Sliding the Rear Mounting Brackets

the Rear Mounting Brackets
  8. Install mounting screws into each of the open rear mounting holes aligned with the rack, starting from the bottom, and secure them tightly.
  9. Visually inspect the alignment of the chassis. If the chassis is installed properly in the rack, all the mounting screws on one side of the rack are aligned with the mounting screws on the opposite side and the switch is level. Figure 5 shows the switch fully secured and installed on four posts of a rack.
