Applications of HP ProCurve 2910al-24G Switch

This part will give a detailed introduction to the network ports on HP ProCurve 2910al-24G switch and cabling solutions for the switch.

Ports on HP ProCurve 2910al-24G Switch
  • Twenty 10/100/1000 ports: All these ports have the “Auto MDIX” feature, which means you can use either straight-through or crossover twisted-pair cables to connect any network devices to the switch.
  • Four dual-personality ports: Each port can be used as either an RJ45 10/100/1000 port or as a mini-GBIC slot for use with mini-GBIC transceivers. By default, the RJ45 connectors are enabled. If a mini-GBIC is installed in a slot, it is enabled and the associated RJ45 connector is disabled and cannot be used. If the mini-GBIC is removed, the associated RJ45 port is automatically re-enabled.
  • Four 10G ports: These ports provide connectivity for 10G speed though either copper or fiber optic media.
Cabling Solution

Since HP ProCurve 2910al-24G switch has 10/100/1000 ports, it can be used for 1G to 1G connection. As shown in the following figure, two 1000BASE-SX SFP transceiver modules are respectively plugged into 1G ports on two HP ProCurve 2910al-24G switches. Then these two 1000BASE-SX SFP transceiver modules are connected via a LC multimode fiber optic cable.

Designed with 10G ports, HP ProCurve 2910al-24G switch can realize 10G to 10G connection just like the above 1G connection. Just replace the 1000BASE-SX SFP transceiver module with 10GBASE-SR SFP+ transceiver. Besides, you can also accomplish 10G to 10 connection by using a 10G SFP+ to SFP+ DAC twinax cable. The following figure shows the cabling solution for you.

TP-Link T1700X-16TS Vs. T1700G-28TQ

Though 40G and 100G have been widely applied in big data center, 10G is still popular with small homelab. Many 10G switches on the market are designed to used with SFP transceiver module and 10G SFP+ transceiver module, while TP-Link has two 10G switches—T1700X-16TS And T1700G-28TQ, which are respectively characterized by 10GBASE-T RJ45 ports or 10/100/1000Mbps RJ45 Ports. This article will make a comparison between them.

Overview of TP-Link T1700X-16TS And T1700G-28TQ

As members of TP-Link’s T1700 Series 10G smart switches, TP-Link T1700X-16TS And T1700G-28TQ are designed to provide increased scalability, higher bandwidth, and enhanced performance. In addition, with physical stacking improving performance and simplifying management, both of them are able to provide reliable, cost-effective and resilient networking solutions for SMBs. As you can see, here are two figures. Figure 1. shows TP-Link T1700X-16TS and Figure 2. shows TP-Link T1700G-28TQ.

Similarities
  • Both of them support rich L2 features, including 802.1Q VLAN, Port Isolation, Port Mirroring, STP/RSTP/MSTP, Link Aggregation Groups, and 802.3x Flow Control function.
  • Both of them support supports L2+ feature static routing, which provides simple network segmentation by routing internal transmissions to make the flow of network traffic more efficient.
  • Both of them support IP-MAC-Port Binding, Port Security, Storm control, and DHCP Snooping, which help to protect the network from broadcast storms, ARP attacks, and more.
  • Both of them support 802.1X, which allows network clients to be authenticated through external Radius servers and the guest VLAN function allows non-802.1X clients to access specific network resources.
