A Closer Look at HP 2910al-24G Switch (J9145A)

Today, big data centers are upgraded from 10G to 40G or 100G, and some small homelabs migrate from 1G to 10G. For some small business data center, 24 port network switch is enough. The switches produced by HP are popular with many data center designers for the high quality and low price. The HP 2910al-24G Switch (J9145A) is highly recommended in many forums. This article will guide you to have a closer look at HP 2910al-24G Switch (J9145A) switch.

Overview of HP 2910al-24G Switch

The HP 2910al-24G switch (J9145A) is

a 24 port switch that can be used to build high-performance switched network. It offers low latency for high-speed networking. For port configuration, it has twenty 10/100/1000 ports, four dual-personality ports, one RJ45 serial console port and four 10G ports. The HP 2910al-24G switch can provide the most flexible and easy-to-deploy uplinks in its class. It can be deployed at enterprise edge and remote branch offices, converged networks, and data center top of rack.

Applications of HP 2910al-24G Switch

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

Ports on HP 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 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 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 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.

The Solution to SFP Transceiver Module Connections

Recently I met a trouble that when I want interconnect WS c2960 24 TC L + 2 SFP with 1000base LH GLC LH SMD or GLC LH SM to WS C3750G 12S + 12 SFP ports, and I do not know which model of GLC LH SMD or GLC LH SM want to select, and I am going to use single mode fiber optic cable 1310m 9/125. If I need single mode SMD (2 fiber counts) or single fiber. I just want to find out WS C3750G12S + 12 SFP ports that 12 SFP ports are SM or SMD use LC connector. The solution to SFP transceiver module connections will be provided in this article.

In fact, I received several answers, someone says, the price between the 2 usually the same but GLC LH SMD SFP transceiver module supports additional option of DOM (digital optical monitoring). So he uses GLC LH SMD, as for which fiber cable, just use the single fiber cable, but I think so I use SMD how can I use single fiber cable, this is one way direction and i think i should use single mode duplex (2 fiber count). And can connect single mode duplex (2 fiber count) fiber cable to WS C3750G 12S.

SFP Transceiver Module

Then someone from Fiberstore answered me that both the GLC LH SM and GLC LH SMD SFP transceiver module supports the IEEE 802.3 1000Base LX/LH standard and be good for compatible with each other. The difference between the two is the case that the GLC-LH-SMD transceiver has additional support for Digital Optical Monitoring capability. As for the second question, 1000base fx sfp, 1000base sx sfp, 1000base lx lh sfp, 1000base zx sfp, 1000base bx10 sfp, DWDM and CWDM SFP transceiver module: LC fiber connectors (single-mode or multimode fiber); 10GBASE-SR, LR, LRM, CX1 (v02 or higher) SFP+ Transceivers: LC fiber connectors (single-mode or multimode fiber).

Then if you have such similar problems, hope it can help you, and there I have a small tips for us, if you want to know where to get sfp transceiver and reach these effects, Fiberstore is a good place to get them, I found it do a professional site, and the price also reasonable, It is worth mentioning that Fiberstore is doing a big sales.
