Technical FAQ

How does the NVT Phybridge FLEX work with VLANs?

VLANs are not required when deploying the FLEX. The FLEX and FLEX Link Adapters act essentially like a “physical” VLAN, this is done by isolating the IP traffic to the parallel network provided by the FLEX system. The FLEX has a default configuration of VLAN 1 with all untagged configuration. This will pass all untagged VLAN traffic or remove the tag from VLAN 1 for data to and from the FLEX.. If you need to configure your IP phones to work with any fixed VLANs (because you may already be using VLANs on your corporate data network), then you will need to configure the FLEX to handle this VLAN traffic.

How is QoS handled?

Because of the point to point topology of the FLEX Link Adapter to the NVT Phybridge FLEX, customized QoS configuration is not normally required. In most instances network configuration is not required but if required QOS can be setup on the switch, please see technical training and manuals for information.

I am using 1 pair or 2 pair Cat5 with my FLEX Link. What is the pinout configuration?

For 1 pair, you will be using pairs 1 and 2.
For 2 pairs, you will be using pairs 1 and 2, and pairs 3 and 6.

How do I set the PoE to manual on a port?

When you are logged into the switch, issue the following command: pal-set-port-poe <1-24|all> manual.
This will allow the full 50 watts to be outputted by the FLEX switch.

How do I enable fibre on my switch?

Once logged into your switch, enter this command: pal-set-gigaport {GbE1|GbE2|GbE} fiber. Make sure to save configuration with pal-conf-save and then reboot the switch.

Features FAQ

What is the operating temperature of the FLEX?

The FLEX can operate in areas with ambient temperature from 0 to 50 degrees C.

Will the FLEX or IP devices work without power?

The FLEX is the only component that requires connection to a power source. The FLEX Link and IP devices plugged into the FLEX Link receive their power from the NVT Phybridge FLEX. The NVT Phybridge FLEX is a complete PoE solution; no local power pucks or adapters are required for the FLEX Link or for the IP device plugged into the FLEX Link.

Does the NVT Phybridge FLEX support CDP and/or LLDP?

The CLEER switch allows for CDP Pass-through communication. LLDP is supported on the FLEX switch.

What are the specifications of the FLEX Link RJ45 port?

The RJ45 port is a 100 Mbps Full Duplex Ethernet port that provides IEEE 802.3af/at compliant voltage to an IP device connected to the RJ45 port. It can output 50 Watts of power based on power source.

Can I attach any Ethernet device?

Yes. The NVT Phybridge FLEX Link supports Ethernet devices that are IEEE 802.3af/at compliant. The connection rate is 100BASE-T. The NVT Phybridge CLEER supports 10/100/1000BASE-T connections on GBE copper and fiber ports.

What is the power consumption of FLEX Link?

The FLEX Link consumes a maximum of 1.5 W.

What is the operating temperature of the FLEX Link?

The FLEX Link can operate in areas with ambient temperature from -40 to 70 degrees C. The FLEX Link does not operate above ambient temperature and should be in an area that gets air circulation.

What is the minimum connection rate?

The FLEX supports 10/100 Mbit full duplex at up to 2000 feet on all downlink ports.

Is there a limit to the number of supported devices off one FLEX Link?

Yes. Each FLEX Link can power one IP device. Some IP phones do allow additional IP devices plugged into them, like a laptop computer, allowing multiple network devices to function off the single FLEX Link connection. (Note: For the daisy chaining configuration you may require additional Earth ground on the FLEX. Please consult the Hardware Installation Manual.)

I have four endpoints in one location that need to be powered up through PoE. What adapter would be needed?

The FLEX-4 can be installed to provide up to 30w per port. This adapter takes one Cat5/6 cable and splits it into four 10/100 RJ45 interfaces. The end devices need to be 802.3af/at compliant.

What is the difference between FLEX Link, FLEX-4, and FLEX-C adaptors?

All these adapters have 10/100 RJ45s and the end-points must be 802.3af/at. The FLEX-C needs to have PoE turned on to manual on the switch, and the FLEX-C is in plastic case. The FLEX-Link and FLEX-4 do not need to have PoE turned on manually at the switch and they are in metal case. Both FLEX Link and FLEX-4 do have the option for an external power supply. Only the FLEX Link can provide up to 50w, meanwhile the FLEX-4 and FLEX-C are able to provide up to 30w per port. The FLEX-C provides PoE and does not negotiate to determine if the end device needs power, meanwhile the FLEX Link and FLEX-4 will negotiate.

What are the data security implications of these devices?

The NVT Phybridge FLEX has two types of network connections, one for Management and one for the Uplink traffic, each configurable to a separate subnet. The traffic is isolated to the GBE Uplink Network ports; in-band management of the FLEX is available through this port, or it may be kept isolated. The MGMT port may also be used for monitoring the FLEX; this port operates independently of the Uplink ports.

Does the NVT Phybridge FLEX support Auto MDIX?

Yes. Both GBE ports support straight through or cross over cables. The straight through cable is recommended.

 

 

Are the NVT Phybridge FLEX and FLEX Link full duplex (sending and receiving data at the same time)?

Yes, traffic between the FLEX and FLEX Link and network ports support full duplex. Supports 200 Mbit/s, 100 Mbit up and 100 Mbit down simultaneously.

Is the FLEX SNMP compliant?

The NVT Phybridge FLEX supports SNMP messaging.

How is the Power over Ethernet provided to the IP device?

The NVT Phybridge FLEX provides power over the FLEX Link RJ45 port, the voltage provided is IEEE 802.3af/at compliant.

What speeds are provided/supported?

The per port signalling rate is 10/100BASE-T on each port. This speed is not affected by distance or cable quality.

4 Pairs – 100Mbps full duplex to 2,000ft (610m)
2 Pairs – 100Mbps full duplex to 1,000ft (305m); 10Mbps full duplex from 1,000ft (305m) to 2,000ft (610m)
1 Pair – 10Mbps full duplex to 2,000ft; FLEX Link will need to be powered locally

Do I need a FLEX Link if the IP device is less than 328ft (100m) away from the switch?

No, you do not need a FLEX Link if the IP device is with the 328ft (100m) Ethernet standard.

What do the LEDs on the FLEX Link represent?

The two LEDs are labeled on the adapter. Link, which shows whether there is a link between the switch and the adapter. It also shows which speed the data is being transmitted on; green for 100Mbps or orange for 10Mbps. The other light is the activity light, which shows whether any data is being sent through the FLEX adapter.

 

How do I calculate the UPS (Uninterruptable Power Supply) requirements for the NVT Phybridge FLEX?

The UPS allows the materials to be switched to emergency battery power for up to several minutes or longer in case of electrical problems, including; power line disturbances, outages, overvoltage, under-voltage, voltage spikes and lightening. To determine more accurate UPS power requirements, you should consider the following:

How much power the FLEX and FLEX Link consumes?

The FLEX24 will draw 20W and the FLEX Link will consume up to 1.5 W of power. Use these values to help calculate your UPS usage.

Please see our power calculators in the partner portal for more detailed explanation on this.

How do I know if my cabling will support these devices?

The NVT Phybridge FLEX and FLEX Link are designed to work with UTP cabling. We recommend use of Cat5 or better cabling for installation of the FLEX. However, this does not mean the FLEX will not work on cabling that does not meet Cat5 specifications.

Can the FLEX damage old legacy equipment if left plugged into wiring?

Yes. The FLEX provides up to 56V DC. This voltage can potentially damage some digital and legacy phone equipment. Please ensure all old legacy phones are disconnected from the wiring infrastructure before you power up the NVT Phybridge FLEX.

Where is the best location to put the FLEX Link?

The best location for the FLEX Link is as close to the UTP connection as possible; on the wall next to the coaxial wall plate or near the RJ45 jack in a cubicle. It is recommended to have the FLEX Link in a place where there is reasonable airflow.

How do I prepare to install the NVT Phybridge FLEX?

The NVT Phybridge FLEX may be physically installed in the server room or telephone closet prior to use. Ensure the FLEX will have adequate air flow. Connect Earth ground connection if required. An Earth ground connection is not normally required with the FLEX Link, however when more than six FLEX Link’s that have multiple IP devices are connected (in daisy chained mode) to any single FLEX, then that FLEX requires an Earth ground connection. Before powering the FLEX, ensure all legacy digital sets and legacy equipment is disconnected from the infrastructure to be used. Prepare RJ45 connections to the Line interfaces.

What UTP connection do I need to connect to the NVT Phybridge FLEX?

A RJ45 male connector on your Cat5 cable is required to connect the UTP cable to the NVT Phybridge FLEX Line Interface.

Does the NVT Phybridge FLEX support Auto MDIX?

Yes. Both GBE ports support straight through or cross over cables. The straight through cable is recommended.

Do I need a special cable to connect to the MGMT port?

No – any standard CAT5 cable will work.

Will my network management software see the NVT Phybridge FLEX and/or the FLEX Link?

The NVT Phybridge FLEX can be seen on the network. The NVT Phybridge FLEX can be configured with an IP address for in-band management (on GBE ports). The NVT Phybridge FLEX can be configured with an IP address on the MGMT port for out-of-band management. The FLEX Link does not have a MAC address and acts as a bridge for the device plugged into the RJ45 port. It is not accessible from the network. Once an IP device is connected to the FLEX Link it will be fully manageable as it is now on the network.

How do I find out the connection rates of the FLEX Link to the NVT Phybridge FLEX?

The rate will be 100BASE-T regardless of distance. If the FLEX Link is within 2,000 feet and the cabling allows a connection the rate be 100BASE-T.
