  • HP ProCurve 1810-24G – Where to find the latest firmware updates

    Having trouble locating the latest firmware for your HP ProCurve switch? Here’s where to find it:

  • HP ProCurve 2510-24 Power Consumption

     

    We measured the ProCurve 2510-24’s power usage:

     

    Idle: 11.9W

    Peak: 14.8W

     

    This was measured on a 240V power circuit with a handful of devices attached (5). The peak wattage was measured during power-on and idle was steady around 11.9W. We would expect power usage to increase as you add more bandwidth-heavy devices; however, now that many of these switches are falling into the hands of home enthusiasts for connecting things like low-bandwidth computers, printers, Raspberry Pis and the like it should stay quite a low figure even with more devices connected.

     

    So, how much does it cost to run? Assuming the minimum power draw is 12W and that electricity costs ~$0.30/KWhr:

     

    Weekly:  2.016KWhr; $0.60

    Monthly: 8.064KWhr; $2.42

    Annually: 104.832KWhr; $31.45

     

    All up it’s not a particularly expensive device to keep running. If you don’t need gigabit speeds this switch can be an excellent choice for getting a large number of devices onto the same network – 100Mbit is more than enough for browsing, light file sharing and streaming, printing, 100Mbit devices like Raspberry Pis and more.

  • HP Procurve 1410-16G (J9560A) Teardown

     

    Well, admittedly there isn’t much tear in this teardown as it’s only a handful of screws to take the casing off. However! If you were curious as to what went into your ProCurve (or were just curious about what is inside switches in general) here you go!

    There’s really some room to spare in there.

    A closer look at the circuit board…

    There’s not a great deal more to look at – we couldn’t pull the heatsinks off this particular board, sadly, so we didn’t get any shots of what was underneath.

    Hope you enjoyed this very brief look at the internals of a modern switch!

  • HP ProCurve 1410-16G (J9560A) review

     

    If you’re in the market for a gigabit switch the HP Procurve line has probably come up in your searches. The 1410-16G is a 16-port gigabit switch, unmanaged, that is also fanless and comes with rack-mounting equipment. Oh, and it’s under $100 AU. With a lifetime warranty. That’s a lot of boxes ticked right there.

     

    hp-1410-16g-02

     

    If you’re used to HP’s 24/48-port rackmount switches the 1410-16G will probably seem quite compact. Meausuring approx. 21 x 11.2 x 4.5cm and weighing ~650gm, it’s certainly not hard to stash away out of sight if needed. The metal chassis helps both with durability and also heat dissipation – and it doesn’t hurt the feeling of quality, either. Jumping straight into the important parts – a closeup of the ports on the front:

     

    hp-1410-16g-05

     

    Nothing out of the ordinary here – two sets of 8 ports, cable clips facing outward as they should be. To the left there’s the indicator lights:

     

    hp-1410-16g-010

     

    Pretty self-explanatory there – and the LEDs are quite appropriately bright, easy to see but not lighting up the entire room. Flipping the unit around to look at the back:

     

    hp-1410-16g-026

     

    Pretty bare back there. A closeup of the main point of interest:

    hp-1410-16g-027

     

    Flipping the unit around to look at the (identical) sides, there’s once again not a great deal to see. Ventilation holes and mounting points for the rack ears. Speaking of rack ears:

     

    hp-1410-16g-012

    They come with all necessary screws and mounting gear. A nice touch – for a lot of home enthusiasts who have a rack 16 gigabit ports may suffice, and this will save a shelf/custom mounting brackets. There’s also wall-mounting hardware supplied:

    …and some nice self-adhesive rubbised feet:

     

    hp-1410-16g-06

     

    The external power brick is reasonably small with a standard 2-pin figure-eight cable going into it:

    A closeup of the printed info for anyone who cares:

     

    hp-1410-16g-08

     

    The unit is silent as you would expect from a fanless unit, and we couldn’t hear any audible hissing/other noises coming from the power brick. In use it’s extremely power efficient, pulling an average of 8W from the wall in use with 14W peak during power-on. It also doesn’t get appreciably hot during use.

     

    As far as performance goes, putting this switch between an iperf client and server showed a steady 945Mbit/s throughput – an excellent result. We weren’t able to test it in a situation where we pumped 16 or 32 gigabits/second through it, which should be where this switch really shines. If our experience with other Procurve switches is anything to go by, this one should be able to deal with very long periods of uptime without issue. We tested this one for three weeks with constant use and it remained trouble-free.

    Given the price point – at or below $100 delivered – the features of this switch make for a compelling product for anyone looking for an unmanaged gigabit switch with 16 ports. Well worth considering.

  • How to reset a ProCurve 2510-24g to default settings

    Here’s one someone asked me today – it’s reasonably straight-forward, though not necessarily obvious:

     

    • Press in both the Clear and Reset buttons (tiny buttons on the left edge)
    • Release the Reset button after the port lights come on (~2 seconds)
    • When the Self-Test LED starts flashing (to the left of the Clear and Reset buttons), release the Clear button.

     

    This resets the switch to the factory default settings, including the IP address. By default this switch uses DHCP for its IP if available; try checking your router’s DHCP client list after the switch boots if you’re having trouble finding it.

     

    These switches are popping up in the hands of enthusiasts more regularly now that they’re quite cheap to come by; they can be quite handy for hooking up a large number of devices which don’t require a gigabit connection (printers, UPS’, modems, IP cameras etc.) – 24 100Mb ports and two gigabit ports in a fanless, rack-mountable chassis can be quite handy.
