DC Power Connection
The Root Plus uses a single D-sub series terminal block plug with two pins. Use two wires to connect to the terminal block: one for the positive terminal and one for the negative terminal.
The current rating of the power wires must be greater than 16 AWG. The power supply to which the Root Plus connects must have a built-in circuit breaker or switch to toggle the power. When installing the Root Plus power wire, push the wire firmly into the terminal as deep as possible and make sure that no exposed (bare) wire can be seen or touched. Exposed power wire is dangerous. Use extreme care when connecting a DC power source to the Root Plus.
WARNING! Working with high-voltage DC power is dangerous. To ensure safety of equipment and regulatory compliance, the DC power connection must be performed by a certified technician.
To connect a power supply:
1 Use a screwdriver to loosen the captive screws on the D-sub's terminal block.
2 Connect one end of a power wire to the Root Plus’s 48 V (return) pin and tighten the captive screw.
3 Connect the other end of the power wire to the positive terminal on the DC power supply.
4 Connect one end of a power wire to the Root Plus’s –48 V (input) pin and tighten the captive screw.
5 Connect the other end of the power wire to the negative terminal on the power supply.
6 Insert the D-sub terminal block’s male connector plug into the Root Plus’s DC in 24–48 V port and tighten the two captive screws.
SFP+ Slot
This is the slot for SFP+ (Small Form-Factor Pluggable) transceivers. A transceiver is a single unit that houses a transmitter and a receiver. The Root Plus does not come with a transceiver. You must use a transceiver that comply with the Small Form-factor Pluggable (SFP+) Transceiver MultiSource Agreement (MSA). See the SFF committee’s specifications.
You can change a transceiver while the Root Plus is operating. You can use a different transceiver to connect to devices with different types of fiber optic or even copper cable connectors.
WARNING! To avoid possible eye injury, do not look into an operating fiber optic module’s connectors.
HANDLING! All transceivers are static sensitive. To prevent damage from electrostatic discharge (ESD), it is recommended you attach an ESD preventive wrist strap to your wrist and to a bare metal surface when you install or remove a transceiver.
STORAGE! All modules are dust sensitive. When not in use, always keep the dust plug on. Avoid getting dust and other contaminant into the optical bores, as the optics do not work correctly when obstructed with dust.

Transceiver Installation
Use the following steps to install a transceiver.
1 Attach an ESD preventive wrist strap to your wrist and to a bare metal surface.
2 Align the transceiver in front of the slot opening.
3 Make sure the latch is in the lock position (latch styles vary), then insert the transceiver into the slot with the exposed section of PCB board facing down.
4 Press the transceiver firmly until it clicks into place.
5 The Root Plus automatically detects the installed transceiver.
6 Remove the dust plugs from the transceiver and cables (dust plug styles vary).
7 Identify the signal transmission direction of the fiber optic cables and the transceiver. Insert the fiber optic cable into the transceiver.

Transceiver Removal
Use the following steps to remove an SFP transceiver.
1 Attach an ESD preventive wrist strap to your wrist and to a bare metal surface on the chassis.
2 Remove the fiber optic cables from the transceiver.
3 Pull out the latch and down to unlock the transceiver (latch styles vary).
Make sure the transceiver’s latch is pushed all the way down, so the transceiver can be pulled out successfully.4 Pull the latch, or use your thumb and index finger to grasp the tabs on both sides of the transceiver, and carefully slide it out of the slot.
Do NOT pull the transceiver out by force. You could damage it. If the transceiver will not slide out, grasp the tabs on both sides of the transceiver with a slight up or down motion and carefully slide it out of the slot. If unsuccessful, contact Zyxel Support to prevent damage to your Root Plus and transceiver.5 Insert the dust plug into the ports on the transceiver and the cables.

Grounding
Earth grounding helps protect against lightning and interference.
The power installation must be performed by qualified service personnel and should conform to the National Electrical Code.The Root Plus must be connected to earth ground to adequately ground the Root Plus and protect the operator from electrical hazards.
Qualified service personnel must confirm that the protective earthing terminal of the building is a valid terminal.
Before connecting the ground, ensure that a qualified service personnel has attached an appropriate ground lug to the ground cable.
1 Locate the ground screw on the rear panel of Root Plus. Place the device with the grooved surface facing upward and the edge with the four ports is closest to you. Feel for the engraved grounding symbol at the bottom-left corner of the grooved surface. The ground screw is directly below it.
2 Remove the ground screw.
3 Secure a green/yellow ground cable (18 AWG or smaller) to the Root Plus’s rear panel using the ground screw.
4 Attach the other end of the cable to the ground, either to the same ground electrode as the pole you installed the Root Plus on or to the main grounding electrode of the building.
Follow your country's regulations and safety instructions to electrically ground the Root Plus properly. If you are uncertain that suitable grounding is available, contact the appropriate electrical inspection authority or an electrician.Warning! Connect the ground cable before you connect any other cables or wiring.
The figure below illustrates how the ground cable (A) is attached to the Root Plus and goes to the earth ground (B).
Grounding Example
The Root Plus should be installed at a 90-degree angle perpendicular to the ground.

Root Plus’s Reset Button
Root Reset Button
Place the Root with the mounting handle facing upward and the port facing toward you. The Reset button is located to the left of the PoE port. Use a pin to press it.
Root’s Reset Button
If you cannot access the Root (Plus) by any method, try restarting it by turning the power off and then on again. If you still cannot access the Root (Plus) by any method or you forget the administrator password(s), you can reset the Root (Plus) to its factory-default settings. Any configuration files or shell scripts that you saved on the Root (Plus) should still be available afterwards.
Use the following procedure to reset the Root (Plus) to its factory-default settings. This overwrites the settings in the startup-config.conf file with the settings in the system-default.conf file.
This procedure removes the current configuration.1 Make sure the Power LED is on and not blinking.
2 Press and hold the Reset button until the Power LED begins to blink. (This usually takes about ten seconds.)
3 Release the Reset button, and wait for the Root (Plus) to restart.
You should be able to access the Root (Plus) using the local GUI’s default settings.
