This procedure walks you through the most basic steps for installing your QFX5200 switch in a rack and connecting it to power.

You can install the QFX5200-32C/QFX5200-32C-L switch in a four-post rack or cabinet using the JNP-4PST-RMK-1U-E partial tool less rack mount kit (RMK). We’ll walk you through the steps to install the switch in a four-post square hole rack using the JNP-4PST-RMK-1U-E RMK.

You can install the QFX5200-48Y on four posts in a rack by using the QFX520048Y-RMKT rack mount kit. See Mounting a QFX5200 in a Rack or Cabinet.

Before you install the switch, review:

Mount the Device by Using the JNP-4PST-RMK-1U-E Rack Mount Kit on a Square Hole Rack

Ensure that you have the following tools and parts available:

An ESD grounding strap—not provided
Number 2 Phillips (+) screwdriver—not provided
A pair of front and rear mounting rails that attach to the rack posts—provided with the RMK
A pair of mounting brackets and 16 flat head M4 x 6 mm Phillips screws. These brackets attach to the device if not pre-installed—provided with the RMK.

To mount the device on four posts in a rack by using the JNP-4PST-RMK-1U-E RMK:

Wrap and fasten the ESD grounding strap to your bare wrist and connect the other end of the strap to the ESD point on the device.
Assemble the mounting rails.
1. Slide the rear floating bracket into the front bracket. See Figure 1.
  Figure 1: Assemble the Mounting Rails
2. Mounting rails assembled. See Figure 2.
  Figure 2: Front and Rear Rails Assembled
Attach the mounting rails to the rack.
1. Align the guide blocks of the rear mounting rails with the rear-post holes. Pull the rear mounting rails toward the front of the rack to lock the rails in place. You will hear a click sound when the latch locks into the corresponding rack holes. See Figure 3.
  Figure 3: Install the Rear Floating Rails
2. Move the latch lock on the front mounting rails to open position, slide the front mounting rails, and insert the guide blocks into the front rack posts. See Figure 4.
  Figure 4: Install the Front Mounting Rails
3. Push the lock latch to the locked position. See Figure 5.
  Figure 5: Front Mounting Rails Lock Latch
4. Visually ensure that the front and rear latches are locked into place on the mounting rails. See Figure 6.
  Figure 6: Mounting Rails Installed and Locked
Attach mounting brackets to the device if not pre-installed. If your device already has the mounting brackets pre-installed than skip this step and move to the next step.
1. Align the holes on the mounting bracket with the screw holes on the side panel of the chassis.
2. Insert the flat head M4 x 6mm Phillips screws to attach the mounting bracket into the aligned holes on the chassis (see Figure 7). Tighten the screws.
  Figure 7: Attach the Mounting Brackets to the Device
Position the device in such a manner that the AIR OUT labels on components are next to the hot aisle.
Grasp both sides of the device, lift it, and position the device such that the mounting rails slide into the channels of the mounting brackets. See Figure 8.
Figure 8: Slide the Device into the Rack
Tighten the two thumbscrews to secure the device. See Figure 9.

Connect to Power

Ground the QFX5200 Switch

To ground the QFX5200-32C or QFX5200-32C-L switch:

Connect one end of the grounding cable to a proper earth ground, such as the rack in which the switch is mounted.
Place the grounding lug attached to the grounding cable over the protective earthing terminal.
Secure the grounding lug to the protective earthing terminal with two screws and washers. See Figure 10
Figure 10: Connecting a Grounding Cable to a QFX5200-32C and QFX5200-32C-L
Dress the grounding cable and ensure that it does not touch or block access to other device components and that it does not drape where people could trip over it.

To connect earth ground to a QFX5200-48Y switch:

Ensure the rack is properly grounded and is in compliance with ETSI ETS 300 253.
Ensure a good electrical connection to the grounding point on the rack.
Attach the ring terminals to each end of the #14 AWG grounding wire.
Connect one of the ring terminals to the grounding point on the FRU panel.
Connect the other ring terminal to the rack ground.

CAUTION:

Do not remove the earth connection until all power supply connections are disconnected.

Connecting AC Power to a QFX5200

Ensure that you have a power cord appropriate for your geographical location available to connect AC power to the switch.

Before you begin connecting AC power to the switch:

Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage).
Ensure that you have connected the switch chassis to earth ground.

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).

To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the chassis to earth ground before you connect it to power. For installations that require a separate grounding conductor to the chassis, use the protective earthing terminal on the switch chassis to connect to the earth ground. For instructions on connecting earth ground, see Connect the QFX5200 to Earth Ground. The switch gains additional grounding when you plug the power supply in the switch into a grounded AC power outlet by using the AC power cord appropriate for your geographical location (see QFX5200 Power Cord Specifications).
Install the power supply in the chassis. For instructions on installing a power supply in a QFX5200, see Installing a Power Supply in a QFX5200.

The QFX5200 is shipped from the factory with two power supplies. Each power supply is a hot-removable and hot-insertable field-replaceable unit (FRU) when the second power supply is installed and running. You can install replacement power supplies in the two slots next to the fan modules without powering off the switch or disrupting the switching function.

Note:

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

To connect AC power to a QFX5200:

Attach the grounding strap to your bare wrist and to a site ESD point.
Ensure that the power supplies are fully inserted in the chassis and the latches are secure. If only one power supply is installed, ensure a that blank cover panel is installed over the second power supply slot.
Locate the power cord or cords shipped with the switch; the cords have plugs appropriate for your geographical location.

Warning:
Ensure that the power cord does not block access to device components or drape where people can trip on it.
Connect each power supply to the power sources. Insert the coupler end of the power cord into the AC power cord inlet on the AC power supply faceplate.
For QFX5200-32C and QFX5200-32C-L models, push the power cord retainer onto the power cord (see Figure 11). Power cord retainers are not available for QFX5200-48Y PSUs.

Power cord retainer
If the AC power source outlet has a power switch, set it to the OFF (O) position.

Note:
The switch powers on as soon as power is provided to the power supply. There is no power switch on the device.
Insert the power cord plug into an AC power source outlet.
If the AC power source outlet has a power switch, set it to the ON (|) position.
Verify that the AC and DC LEDs on each power supply are lit green.
If the amber fault LED is lit, remove power from the power supply, and replace the power supply (see Removing a Fan Module from a QFX5200). Do not remove the power supply until you have a replacement power supply ready: the power supplies or a blank cover panel must be installed in the switch to ensure proper airflow.

CAUTION:
Replace a failed power supply with a blank panel or new power supply within 1 minute of removal to prevent chassis overheating.

CAUTION:
A system reboot with Routing Engine FPGA version 7.1 might not successfully boot the Junos OS software. In case of a system reboot failure, you need to power cycle the switch. To check the current FPGA version, issue the show chassis firmware command.
