This procedure walks you through the most basic steps for installing your QFX5110 switch in a rack and connecting it to power.

You can mount the QFX5110 switches on a square or threaded hole four-post 19-in. racks using the JNP-4PST-RMK-1U-E rack mount kit (RMK). We’ll walk you through the steps to install the QFX5110-32Q and QFX5110-48S switches in a four-post square hole rack using the JNP-4PST-RMK-1U-E RMK.

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 rack mount kit
A pair of mounting brackets and 16 flat head M4 x 6mm Phillips screws. These brackets attach to the device if not pre-installed—provided with the rack mount kit

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

Wrap and fasten the ESD grounding strap to your bare wrist and an 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 QFX5110 Switch
Connect the Power Cord and Power On the QFX5110 Switch

Ground the QFX5110 Switch

To ground the QFX5110 switch:

Wrap and fasten one end of the electrostatic discharge (ESD) cable grounding strap around your bare wrist, and connect the other end to a site ESD point.
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 that is 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 QFX5110
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.

Connect the Power Cord and Power On the QFX5110 Switch

To connect the power cord:

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 that a 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. See QFX5110 AC Power Specifications.

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.
Push the power cord retainer onto the power cord (see Figure 11).

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 QFX5110). 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 one minute of removal to prevent chassis overheating.
