Commute it wisely
If you are the head of the IT department in a large company, who was suddenly faced with a question of cost cutting, then our advice to you in most cases will be outsourcing.
But if in your organization the IT department consists of you alone (although in reality you wanted to work as a sales manager, not an IT specialist), and the question of cutting IT costs still arose before you, then you don’t have -hh.ru though , let's first try a slightly different link - hp.ru.
How about VoIP and LAN, working on the principle of "set up and forget"? The new HP ProCurve 2520 switch is such a very peculiar outsourcing when you put worries about the normal operation of the network on hardware.
For your tasks, you can choose one of 4 models of the 2520 series with 8 or 24 ports (two models of Fast and Gigabit Ethernet). All models have interchangeable SPF bays with dual-use Gigabit ports that can be used to establish connections over both copper and fiber optic channels.

Our proprietary Auto-MDIX technology allows the switch itself to configure all ports for the desired cable type (straight or crossover).
Also, all models support Power over Ethernet (PoE) technology, which allows power supply to devices connected to the switch (up to 15.4 W per port) via the same cable that the data is transmitted to. Thanks to this, you can seriously simplify your life by placing VoIP phones, wireless hotspots and IP cameras in your office — now employees can plug in their kettles to any outlet. And the LLDP-MED (Media Endpoint Discovery) extension will help automatically identify most devices.
Load from heavy traffic generators like cameras and telephones is also not a problem - packages up to 9216 bytes (model 2520G) are supported. And up to 8 ports can be combined per trunk, which, in addition to throughput, seriously improves fault tolerance by creating redundant connections. At the same time, the ability to limit the speed of traffic will allow to cut off the transmission of unwanted content.
Configuring complex VLAN configurations is greatly facilitated by the support of the IEEE 802.1s Multiple Spanning Tree protocol. On the basis of the ports, you can create up to 256 VLANs at the same time - with a large future margin, as they say.
Security features aren’t even at the beginner level. The distribution of rights and privileges for the manager (reading and writing the settings) and the operator (read only) is available - this is useful if your accountant is addicted to system administration. RADIUS / TACACS + authentication will allow using a password server for access control. You can encrypt everything: Secure Shell protocol (SSHv2) for secure remote access via the command line interface over IP networks; SSL protocol for HTTP traffic that provides secure access to the switch management graphical interface through a browser; SNMP v3 protocol for encrypting traffic between the switch MIB and network management software; and finally, the SFTP protocol: encryption when uploading and downloading the configuration file
To reduce power consumption and noise reduction in 24-port models, a dynamically adjustable rotational speed fan is used, and in 8-port models there is no fan at all. Unused ports and LEDs of the switch are automatically converted to low power mode.
Finally, when your building neighbors appreciate your technological superiority, you can consolidate up to 16 HP ProCurve 2520 switches into a single stack, managed by a single IP address. This is to start supplying IT outsourcing services to them and compete with HP.
And, traditionally, the HP ProCurve lifetime warranty is provided on all HP ProCurve 2520 models.
Yes, and our switches are installed on the International Space Station. Not only ours, of course, but ours too. Well, okay, this is too much. Questions, criticism, suggestions are welcome!
