Juniper Networks website and update the installation base data if there is any addition or change to the installation base
or if the installation base is moved. Juniper Networks will not be held accountable for not meeting the hardware replacement
service-level agreement for products that do not have registered serial numbers or accurate installation base data.
Register your product(s) at https://tools.juniper.net/svcreg/SRegSerialNum.jsp.
Update your install base at https://www.juniper.net/customers/csc/management/updateinstallbase.jsp.
WARNING: Ensure you understand and follow all ESD safety procedures to prevent damage to the
switch and switch components. Perform all hardware installation tasks with an ESD grounding strap
attached to your bare wrist and to a site ESD point on the chassis.
CAUTION: Do not mix:
•AC and DC power supplies in the same switch chassis.
•Power supplies and fan modules with different airflow. All modules must use the same airflow
direction, either airflow in (AFI) or airflow out (AFO) or the chassis will overheat. With AFO, air flows
from the ports to the field replaceable units (FRUs); with AFI, it flows from the FRUs to the ports.
Install the Power Supplies (If Not Already Installed)
The EX4600 switch can operate with one power supply installed. However, two power supplies must be installed for
redundancy so that you can remove and replace one, if required, without powering off the switch or disrupting switch
functions. If pre-installed, proceed to the next section, Install the Fan Modules (If Not Already Installed).
1. Taking care not to touch power supply components, pins, leads, or solder connections, remove the power supply from
its bag.
2. Using both hands, place the power supply in the power supply slot on the FRU panel of the switch and slide it in until
it is fully seated and the locking lever slides into place.

Mount the EX4600
The EX4600 switch can only be mounted in a four-post rack configuration. To mount the switch:
NOTE: If you are mounting multiple units in the rack, mount the heaviest unit at the bottom and mount the
others from bottom to top in order of decreasing weight. The switch weighs approximately 21.4 lb (9.7 kg).
Installing the EX4600 switch in a rack or cabinet requires two people; one person to lift the switch while the
other secures it to the rack.
1. Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the
building structure.
2. Determine whether the end with FRUs or the ports will be placed at the front of the rack.

3. Align the holes in the side mounting-rail with the holes on the side of the chassis.
4. Attach the side mounting-rail to the switch using six mounting screws. Use cage nuts and washers if your rack requires
them.
5. Repeat Step 3 and Step 4 on the opposite side of the switch.
6. Have one person grasp both sides of the switch, lift it, and position it in the rack so that the front bracket is aligned
with the rack holes.
7. Have a second person secure the front of the switch to the rack by using four mounting screws (and cage nuts and
washers if your rack requires them). Tighten the screws.
8. Continue to support the switch while sliding the rear mounting-blades into the channel of the side mounting-rails and
securing the blades to the rack. Use the four mounting screws (and cage nuts and washers if your rack requires them)
to attach each blade to the rack. Tighten the screws.
9. Ensure that the switch chassis is level by verifying that all the screws on the front of the rack are aligned with the
screws at the back of the rack.

Connect Power to the EX4600
IN THIS SECTION
Connecting EX4600 to AC power | 5
Connecting EX4600 to DC power | 5
All EX4600 switches, except the EX4600-40F-S switch, are supplied with two factory-installed power supplies and power
cords. Order separate power cords for the EX4600-40F-S.
Connecting EX4600 to AC power
To connect power to an AC-powered switch:
1. Connect each power supply to a dedicated power source outlet.
2. If the AC power source outlet has a power switch, set it to the OFF (0) position.
3. Insert the coupler end of the power cord into the AC power cord inlet on the AC power supply faceplate.
4. Push the power cord retainer onto the power cord.
5. Insert the power cord plug into the power source outlet.
6. If the AC power source outlet has a power switch, set it to the ON (|) position.
7. Verify that the AC and the DC LEDs are lit green and are on steadily.
Connecting EX4600 to DC power
To connect power to a DC-powered switch:
1. Ensure a licensed electrician has attached a cable lug to the grounding and power cables you supply.
2. Verify that the DC power cables are correctly labeled before connecting the power supply. The DC power supply has
four terminals labeled V+,V+,V–, and V–; the power source cables are labeled positive (+) and negative (–). The V+
terminals are often referred to as +RTN, and V– terminals are referred to as –48 V.

CAUTION: There is no standard color coding for DC power cables. The color coding used by the
external DC power source at your site determines the color coding for the leads on the power
cables that attach to the DC power input terminals on each power supply.
3. Ensure that the input circuit breaker is open so that the voltage across the DC power source cable is 0 V and that the
cable leads do not become active while you are connecting DC power.
4. Remove the clear plastic terminal block cover.
5. Remove the screws on the terminals using a screwdriver. Save the screws.
WARNING: Ensure that the power cables do not block access to device components or drape
where people can trip on them.
6. Connect each power supply to the power sources. Secure power source cables to the power supplies by screwing the
ring lugs attached to the cables to the appropriate terminals by using the screw from the terminals.
•Secure the ring lug of the positive; (+) DC power source cable to the V+ terminal on the DC power supply.
•Secure the ring lug of the negative (–) DC power source cable to the V– terminal on the DC power supply.
•Tighten the screws on the power supply terminals until they are snug using the screwdriver, but do not overtighten.
7. Replace the terminal block cover and close the circuit breaker.
8. Verify that the IN and OUT LEDs on the power supply are lit green and are on steadily.
