24 Port PoE Gigabit Switch Managed vs Unmanaged: Which One to Choose?

January 10th, 2018

Along with its incredible speed, bandwidth and flexibility, industrial and growing features and functions from the commercial and industrial spaces, all of these can make the simple choice of a switch seem overly complex. To select a right and suitable switch for your network, you have to consider many factors, such as PoE switch or non PoE, managed or unmanaged. And nowadays, 24 port poe gigabit switch is very common and popular with its potential ability to expand operation. Here in this article, we will make a comparison between 24 port PoE gigabit switch managed vs unmanaged to help customers have a clear understanding of them and make the right decision.

24 Port PoE Gigabit Switch Managed vs Unmanaged: What’s the Difference between PoE and Non PoE?

PoE (Power over Ethernet) is a capability that facilitates powering a device (such as an IP phone, IP Surveillance Camera, or Wireless Access Point) over the same cable as the data traffic. One of the advantages of PoE is the flexibility it provides in allowing you to easily place endpoints anywhere in the business, even places where it might be difficult to run a power outlet. One example is that you can place a Wireless Access Point inside a wall or ceiling. Switches deliver power according to a few standards – IEEE 802.3af delivers power up to 15.4 Watts on a switch port whereas IEEE 802.3at (also known as POE+) delivers power up to 30 Watts on a switch port. With a 24 port poe gigabit switch, you can use it in many ways. For example, to power an IP Megapixel Camera network, you’ll need a total power per port of 30W. For a 24 port poe gigabit switch with a power budget of 360W, you can continue to add IP cameras until you reach your budget. If you have 2 SFP ports, you can also connect to multiple switches, as well.

24 Port PoE Gigabit Switch Managed vs Unmanaged: What’s the Difference between Managed and Unmanaged?

Generally speaking, network switches can be classified into two categories: managed and unmanaged. A managed 24 port gigabit poe managed switch refers to a network switch that can be accessed and programmed by a network manager. These switches can be managed on site or remotely. A managed switch is typically used in larger office settings. There are a variety of 24 port gigabit poe managed switch available from leading manufacturers such as FS.COM. On the contrary, an unmanaged switch does not allow a manager to change any settings. It functions according to factory specifications. An unmanaged switch is ideal for home use where modifications are not necessary. More details between managed switches and unmanaged switches can be obtained from the following table.

Type Managed Switches Unmanaged Switches
Features Dynamic ARP Inspection, IPv4 DHCP snooping, QoS, SNMP, VLAN, CLI, IP routing, port mirroring, redundancy, etc. Fixed configuration—doesn’t support any configuration interface or options
Performance Switch can be configured
Control over Access
Control over LAN traffic—Priority
SNMP—Allows for remote troubleshooting of the network
Plug and play with limited configuration like default QoS settings
Security Very good. Provide protection of the data plane, control plane and management plane Not very good. No security other than accessories such as lockable port cover
Costs Expensive Less expensive
Application Places Data center, large size enterprise networks Small size business network, home, lab, conference rooms, etc.

24 Port PoE Gigabit Switch Managed vs Unmanaged: Which One to Choose?

If you are researching 24 port poe gigabit switch, you’ll inevitably come to a crossroads. Do you choose managed or unmanaged switches? Actually the choice is really quite simple. As we have discussed in the previous text, a managed 24 port poe gigabit switch is always better. Why? Security features for starters. They allow administrators visibility and control. But the benefits don’t stop there. 24 port gigabit poe managed switches also offer the ability to program each port individually, which can save power and keep your network operating at peak efficiency. As your organization grows, your business needs will continue to evolve. Having a device that can respond to the dynamic shape of your operation is a good investment. A 24 port gigabit poe managed switch can be used for many things such as IP cameras, wireless access points, and thin clients to fulfill your potential needs. If you don’t need 24 port gigabit poe managed switch, you many still find non poe 24 port gigabit switch at FS.COM.

All You Need to Know about 56G QSFP+ to QSFP+ DAC Twinax Cable

December 7th, 2017

DAC is the short name for direct attach cable. Currently, there are many different types of DAC twinax cables on the market such as SFP+ DAC Cable and QSFP DAC Cable. Terminated with transceiver-style connectors, they are designed to be used in the same ports as a typical SFP+ or QSFP transceiver, with no need for adaptors or converters, replacing two optical modules and a connectorized optical fiber with a twinax copper cable assembly. Here in this post, we will mainly focus on 56G QSFP+ to QSFP+ DAC Twinax Cable.

Basics on 56G QSFP+ to QSFP+ DAC Twinax Cable

The 56G QSFP+ to QSFP+ DAC twinax cable, as implied in the name, uses QSFP+ MSA and by using the inexpensive copper twinax cable with QSFP+ connectors on both sides, and provides 56 Gigabit Ethernet connectivity between devices with QSFP+ interfaces,which is suitable for very short distances and offers a highly cost-effective way to establish a 56 Gigabit link connectivity. Unlike 40G (10Gx4) QSFP+ DAC twinax cable, a kind of 40gb ethernet cable, the 56G QSFP+ DAC twinax cable is designed for 56G (14Gx4) InfiniBand FDR interconnecting networking applications such as high-performance computing (HPC), enterprise networking including top-of-rack switching and network storage markets.

56G QSFP+DAC

The 56G QSFP+ DAC twinax cable is fully comply with QSFP+ Multi-Source Agreement (MSA) standards SFF-8436 and InfiniBand FDR specifications. And it is developed specifically as a cost-effective and lower-power alternative to 56G QSFP+ optics and 56G QSFP+ active optical fiber cable (QSFP+ AOC).

How to convert QSFP to RJ45 for Network Connection

December 2nd, 2017

We know that in the present market, there are different types of ports for switches, such as RJ45 port, SFP+ port, QSFP port and etc. Generally speaking, the more ports a switch is equipped with, the more devices the switch can be connected to. Different ports enable switches to other devices via fiber or copper. So what are the different between these ports? How should we wire them respectively? How get different ports connected? Here in this article we will mainly focus on QSFP Port and RJ45 Port.

QSFP to RJ45: What Is QSFP Port

The QSFP port is to be inserted for 40 Gbps transceiver module that offers high-density 40 Gigabit Ethernet connectivity options for data center and high-performance computing networks. The QSFP transceiver module is a hot-swappable, parallel fiber-optical module with four independent optical transmit and receive channels. These channels can terminate in another 40 Gigabit Ethernet QSFP+ transceiver, or the channels can be broken out to four separate 10 Gigabit Ethernet SFP+ transceivers. The QSFP+ transceiver module connects the electrical circuitry of the system with either a copper or an optical external network.

QSFP to RJ45:What Is RJ45 Port

Unlike QSFP, which is used to support QSFP modules. RJ45, incidentally standing for registered jack 45, is the ubiquitous Ethernet style data port found on switches, routers and network cards. The RJ45 style connectors and ports are also commonly found on Ethernet, serial and ATM IMA cards and interfaces. However, the most common use by far is with Ethernet data connections from desktop PC network cards, Wi-Fi access points, data switches and routers in home and corporate networks. For twisted pair cables like cat5, cat6 and cat7 etc, they are all with RJ45 connectors.

Solution for QSFP to RJ45

Now we know QSFP and RJ45 are different ports which can be used by different transceivers. The QSFP spec is different from RJ45 spec. The former is to be prepared for QSFP modules, while the latter is designed to support GBIC, SFP and SFP + modules. So the to connect QSFP to RJ45 port cannot be achieved directly. Good news is that currently we’ve got product like QSFP+ to 4 x 10/100/1000BASE-T (RJ45) Breakout Cable. For this breakout cable, one connector is QSFP and the other connector is 4 x RJ45, thus we can easily get a connection between QSFP and RJ45.
