PoE (Power Over Ethernet) technology brings new capability and device expansion to network deployments, such as IP cameras, indoor wireless access points, VoIP (Voice over IP) phone systems which are capable of receiving power over Ethernet cabling. Among them, VoIP phone is a fast-growing area for small and medium-sized businesses (SMBs). If you’re switching to VoIP, then it’s critical to ensure that your network infrastructure is fully optimized for it. FS.COM recommends two lines of 24-port PoE switch for VoIP phones, which offers configurable Layer 2+ network switching features like VLANs and fast Ring Protection Protocol (RSTP) to power your network for high-quality VoIP.
VoIP phones or IP phones use VoIP technologies to allow telephone calls to be made over an IP network such as the Internet instead of the ordinary PSTN (public switched telephone network). The RJ-45 connector on an IP phone is an Ethernet port used to connect the phone to your network, through which the IP phone can communicate with any other IP-based device on the network. Today’s high-end, state-of-the-art phones often have two ports, one to connect to the switch and the other connects to a co-located PC. If the co-located PCs on the network require Gigabit speed, then of course a Gigabit switch is required. When considering VoIP phone options, you’ll notice that they vary in Ethernet speeds and support for PoE, which makes placement far more convenient. Therefore, a PoE managed Ethernet switch is required to connect to VoIP phones. These PoE managed Ethernet switches for VoIP phones are available with 8, 16, 24 or 48 ports, among which the 24-port PoE switch is the most prevalent and affordable on the market.
When connecting VoIP phones, are you confused about which 24-port PoE switch is right for you? If you want an efficient and high-quality VoIP network, you will absolutely need excellent Ethernet switches. FS.COM recommends two lines of 24-port PoE managed switches for VoIP phones: S1400-24T4F 24-port Gigabit PoE+ Managed Switch and S1600-24T4F 24-port Gigabit PoE+ Managed Switch. With the comprehensive features listed below, they can provide a secure and flexible solution to enable almost plug-and-play network connectivity for VoIP phones and workstations.
As shown in the figure below, both FS S1400-24T4F and S1600-24T4F PoE managed switch come with 24 10/100/1000Base-T RJ45 Ethernet ports, 1 console port, 2 combo ports and 2 dedicated SFP ports for fiber uplinks.
FS S1400-24T4F and S1600-24T4F 24-port PoE switches fully comply to the IEEE 802.3af standard for PoE up to 15.4W per port and the latest IEEE 802.3at standard for PoE+ up to 30W per port. With 24 Gigabit RJ45 ports, these two types of 24-port PoE switches are capable of connecting up to 24 power-hungry VoIP endpoints to the network with a single wire for power and connectivity. Both of them come with 52Gbps switching capacity with 8K MAC address table, 9KB Jumbo Frame and 4MB Buffer Memory. For each of them, the input voltage is about 100-240V and output voltage is 52V. FS S1400-24T4F and S1600-24T4F are solidly built excellent switches from the firm with a data transfer rate of 1,000 Mb/s. With configurable Layer 2+ network switching features like VLANs and RSTP, they can achieve real ring loop redundancy protection, providing security, performance, quality of services, central managed and other network control capabilities.
|Max. Power Consumption||400W||600W|
|PoE Standard||IEEE 802.3af/at||IEEE 802.3af/at|
|Gigabit RJ45 Ports||24||24|
There is no significant difference between FS S1400-24T4F and S1600-24T4F 24-port PoE switches. The only aspect that differs them is the power capacity, namely the maximum power PoE switches can provide. The maximum PoE power budget for FS S1400-24T4F is 400W while 600W for FS S1600-24T4F. If you want to connect more IP phones to the PoE switch, FS S1600-24T4F is superior than S1400-24T4F, because it can provide more power to the devices connected in the IP phone network. But keep in mind you should never exceed the power threshold of the PoE switch when adding IP phones, or the devices couldn’t get sufficient power and would not boot up properly.
The 24-port PoE switches can be easily mounted in a rack, on a wall, or on desktop. Here presents an example of using FS S1600-24T4F 24-port Gigabit PoE switches to connect IP phones, desktops, etc. When the PoE powered IP phone is connected to the FS S1600-24T4F Ethernet switch, a number of different protocols have to operate in a particular sequence in order to enable secure network access for the phone, and to dynamically configure the phone and the switch to interoperate correctly. The IP phones, IP PBX and voice gateway are all on the same subnet and same VLAN. The desktops are connected to the switch via Ethernet copper cables which are very convenient and cost-effective for places like offices. All the traffic is managed by the single FS S1600-24T4F PoE switch which can automatically apply QoS policies to ensure high QoS at all times, even when the network is congested. It is a complete solution compatible with all major signaling protocols, and is ideal for a small business or branch office that wants to enjoy the benefits of VoIP with maximum simplicity.
Note: For IP phones, the 15.4W per port provided by PoE is adequate. But in practice, the specific required power per IP phone should be obtained from the vendor. And the total wattage requirement can also be calculated by: Average watts per IP phone x total number of phones = total PoE budget required. The total PoE budget of the IP phones on the network can not exceed the power capacity of the switch – 600W.
Selecting the best Ethernet switches for your VoIP network proves to be a big challenge since there is an abundance of Ethernet switches on the market, each addressing a certain type of audience and varying in Ethernet speeds in terms of PoE. FS.COM 24-port PoE switch is the cost-effective & efficient PoE solution to connect VoIP phones, which reduces the need for extra outlets and extension cables and saves deployment cost as well as labor efforts. With Auto-MDI/MDIX capability, the 24-port PoE switch provides fast plug and play setup, eliminating the need for a crossover cable while auto-negotiation detects the link speed of the attached device and adjusts for compatibility and optimal performance, making the switch backwards compatible with older network devices.
