Unpacking and Mounting the EX9251 Switch

Unpacking an EX9251 Switch

EX9251 switches are shipped in a cardboard carton, secured with foam packing material. The carton has an accessory compartment and contains the quick start instructions.

CAUTION:

EX9251 switches are maximally protected inside the shipping carton. Do not unpack the switches until you are ready to begin installation.

To unpack the switch:

  1. Move the shipping carton to a staging area as close to the installation site as possible, but where you have enough room to remove the system components.
  2. Position the carton so that the arrows are pointing up.
  3. Open the top flaps on the shipping carton.
  4. Remove the accessory box, and verify the contents against the parts inventory on the label attached to the carton.
  5. Pull out the packing material holding the switch in place.
  6. Verify the parts received against the inventory on the label attached to the carton. See Parts Inventory (Packing List) for an EX9251 Switch.
  7. Save the shipping carton and packing materials in case you need to move or ship the switch later.

Installing and Connecting an EX9251 Switch

The EX9251 switch chassis is a rigid sheet-metal structure that houses all components of the switch. The switch is shipped in a cardboard carton, secured with foam packing material. The carton has an accessory compartment and contains the quick start instructions.

To install and connect an EX9251 switch:

  1. Unpack the switch by following instructions in Unpacking an EX9251 Switch.
  2. Mount the switch by following instructions in Mounting an EX9251 Switch on a Rack or Cabinet.
  3. Connect the switch to earth ground by following instructions in Connect Earth Ground to an EX Series Switch.
  4. Connect power to the switch by following instructions as appropriate for your model:
  5. Perform initial configuration of the switch by following instructions in Connecting and Configuring an EX9251 Switch (CLI Procedure).
  6. Set the switch’s management options by following the appropriate instructions:

Mounting an EX9251 Switch on a Rack or Cabinet

You can mount an EX9251 switch on four posts of a rack that complies with either of the following standards or in a cabinet with a rack that complies with either of the following standards by using the mounting brackets provided with the switch:

  • 19-in. rack—A 19-in. (450 mm) rack as defined by the Electronic Components Industry Association (http://www.ecianow.org).

  • ETSI rack—A 21-in. (500 mm) ETSI rack as defined in the European Telecommunications Standards Institute (ETS 300 119) published by the European Telecommunications Standards Institute (ETSI).

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. 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.

CAUTION:

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:

One person must be available to lift the switch while another secures the switch to the rack. The weight of a fully configured chassis is 22.7 lb (10.3 kg).

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

Mounting an EX9251 Switch on a 19-in. Rack

Before you begin mounting the switch on a 19-in. rack, ensure that you have the following parts and tools available:

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

  • Two front-mounting brackets and 16 screws to secure the brackets to the chassis (provided in the accessory box shipped with the switch)

  • Two rear-mounting brackets (provided in the accessory box shipped with the switch)

  • Eight screws to secure the chassis to the rack (not provided)

  • Cover panels for power supply slots

To mount the switch on a 19-in. rack:
