• Aironet 2802i Radio0 has not started, not enough power POE on SG300-28PP switch

  When I restart Aironet 2802i which is powered by 28PP SG300 28 - Port Gigabit PoE + switch, I saw the following message:

  [* 13:47:31.8044 26/09/2016] Radio0 has not started, not enough power POE
  [* 13:47:31.8173 26/09/2016] DOT11_DRV [0]: set_channel channel set to 11

  [* 13:47:33.6506 26/09/2016] Radio1 not started, not enough power POE

  Series Aironet 2800 get started guide mentions "any 802.3at (25.5 W) compatible switch port" and SG300-28PP seems to be consistent.

  Please advise, thank you.

  Oh sorry, I got a 2602 in my head, but you use the built-in WLC? I have not had the chance to play with those, but assumes that it will be the same.

• EPS-470 for power and switches Dell PowerConnect - 2 outputs or 1?

  I do some design network (including the grids and the PDU.  In many cases, I need a power supply EPS-470 to provide PoE to 48 ports on a PowerConnect switch.

  I need to know, do I need an output for the switch and the other to the EPS-470, or once the switch is hung in the EPS-470 just do I power connected to whom?  I just need to know if I need one or two points of sale so I plan accordingly for the PDU.

  Hi prepIT,.

  The EPS-470 adds more power, so you need two, one for the switch and the other to the EPS.

• 10GBase-T module lights turn off after turning the power on switch

  I have a pc6248 with the latest version of the firmware and a 10gbase-t module which lights do not go after turning on the switch.  But if I do a "reload", the module lights turn off and works normally.  So there's something about switching on the switch that causes the module lights stay on and the module is not connect or traffic through until I do a 'reload '.  I have another module that works normally in the switch, so it doesn't seem to be a problem with the switch.  Has anyone else seen elsewhere?  Clues about what can happen?  Any help would be appreciated, thanks.

  I see, unfortunately there isn't really anything that can be done of these modules. No update of the firmware or something like that.  Having two of the same exact module, 1 works and 1 does not work, indicates a problem with the module. Is the module a recent purchase? If so, you can get toggled.

  With the defective module installed, if you issue a shutdown command and then a no shutdown interface command, behavior change at all?

• Satalite L500-1XD: cutting short lack buttons next to ' POWER on ' switch

  I just bought a Satalite L500 - 1XD Intel i3, 4 GB DDR3 laptop off Argos. Between the two speakers, I noticed there is only 1 button to turn it on. I've seen a lot of photo of this laptop and I saw this laptop to Tesco and all have 5 buttons between the 2 speakers. What are the shortcut keys for PLAY/PAUS, FAST FORWARD, MUTE, REWIND, etc. I would like to know Toshiba has 2 models for L500-1XD and if yes, who is the last. I would be grateful if you can let me know if your laptop has 5 buttons on shortcut or not so I can get back to Argos as soon as possible.

  Can you also tell me you have 2 ports eternet. One of the socket on mine is blackened and only got 1 hold eternet.

  Thank you very much

  Hi mate

  Don't worry it's all goes well with your laptop.
  Always is that there are models of different laptops on the market with a different hardware configuration
  So some models support the command buttons, some are equipped with a single button
  This is nothing unusual.

• C1250 AP required using POE power

  Hello

  I have questions about the AP C1250.

  -What are the energy needs POE for the AP and the Cisco 3560 and 4900 is the correct POE power to support?

  -Also, should I get the injector of power to power the switch online usage? Another word if PoE, can I connect the Ethernet cable between the switch port directly into the Ethernet port on the AP without the power injector?

  Really enjoyed for more information.

  1250 with a single radio or 802. 11A / n and 802.11bg / n

  15.4

  1250 with two 802. 11A / n and 802.11bg / n radio *.

  18.5W

  Basically you can use the 802.3af switch power to 1250, as long as you have the intention to use only 1 radio. If you did, it there would be no power injector and here for the AP could have just an ethernet cable from the ap to the switch.

  However, if you plan to use two radios, power exceeds 15.4 (802.3af maximum) which means that you will need to use a special power injector for it or the power room. Otherwise, I think that there are a few switches that support this 'high power' mode, but I don't know what they are...

• SG300 - 28 p: POE power drops every few minutes

  Hi all

  We have a SG300 - 28 p which, at intervals between 5 and 30 minutes or more, lower power to all its ports POE-powered and then immediately restores power. Switch logs nothing when this happens other than to record that the ports went down and back up, even with debug logging enabled. Non - POE ports are not affected.

  When the problem started there were only four POE devices on the switch and we are far under our power budget. (During the test, I added a fifth device, see below.)

  Not all combinations of devices cause the drops occur - specifically, it seems that having devices on ports next to each other causing the drops. When the drops occur, absent the increment of POE devices all counters. I noticed this thread earlier here seemed similar:

  https://supportforums.Cisco.com/thread/2165089

  but in this case, he got no power at all in the adjacent configurations, instead of having to drop all the several minutes.

  I have the 1.2.2.7.6 ready to go new firmware, I will update this when I get a chance to test it. Unfortunately, it's a switch of production, but it's a with relatively few devices to it so far. If need be, I have a sf300 - 48P I can exchange this sg300 ENJOI trials.

  Thank you for anything you might suggest.

  Here are the details:

  -' Phone' is a phone to IP Avaya 4610SW or 5610SW (class 2)

  -"Watchdog" is an environmental monitor IT Watchdogs Watchdog 100 (class 0)

  -"WAP" is a Cisco WAP4410N (class 3)

  All initially due to lack of combination:

  GI10 phone #1

  gi22 phone #2

  dog guard gi23

  WAP gi24

  would result in the POE power to place on all ports, every 5 to 30 minutes.

  I disabled Green Ethernet completely - no change.

  And then made the following tests:

  1. "power never inline" on gi23 and gi24: problem disappeared

  2. 'inline power auto"on gi23 and gi24: problem is back

  3 ' power inline never' on gi23 only: problem disappeared

  4 ' auto of inline power' on gi23: problem is back

  5 ' power inline never' on gi24 only: problem disappeared

  6. "power inline auto" on gi24: problem is back.

  I left gi23 powered throughout the night and it was stable: it's about 10 hours without any problem.

  This morning, tried the following configs:

  Hi Rich, reference this photo I just drew is a rough interpretation of how a switch 24 ports has guts. Each + block represents a processor. The numbers below represent the port Bank that corresponds to the transformer. Of course, MODULE POE is clearly identified. Each module 12 POE ports for services.

  I think you have a completely different question. If the POE works for 5 to 30 minutes, it can be a problem of layer 1 (bad son) or a different, perhaps material condition being disturbed. If the switch is at fault, it seems more likely to be defective to a unit of buggy.  I did a lot of research on the operation of the switch ASIC, transformer and modules of POE in the cohesion.

  Quite frankly, I think you should go to the 1.2.7.76 firmware, factory reset the device and test all the ports you want using the same equipment. If maintaining the POE fall every 5 to 30 minutes and you are absolutely positive, that it is not a question of layer 1 or a configuration problem on your products, can I just replace the switch.

• Are there plans for the new ESW 500 models switch with PoE capability?

  I know that current models of ESW 500 switch don't have enough capacity to power all the switchports to 15.4, even if the ESW-540-8 p model has almost enough capacity to power all the switchports to 15.4.

  Reasons why new ESW 500 switch with PoE capacity are necessary:

  • The existing PoE 500 ESW switches have not always enough when these devices are deployed with the UC500:
    • 7945, 7965 and 797 x phones
    • series phones (not yet supported with the SBCS solution) 9900 and 8900
    • PVC2300 Surveillance Cameras
    • AP541N access points
  • The UC560 comes with all the PoE ports and requires at least an ESW switch be deployed
  • Version 48 ports gigabit switch ESW is currently available only in the version not PoE, and we need a version of 48 gigabit ports for users of the UC560 solution.

  Existing ESW 500 switch PoE capabilities are:

  • ESW-520-8 P: 60W
  • ESW-540-8 P: 120W
  • ESW-520-24 P: 180W
  • ESW-540-48P: 380W
  • ESW-540-24 P: 280W

  PoE of ESW 500 switch capabilities supporting 15.4 full power on all PoE PoE ports are:

  • 8 port: 123.2W
  • 24 port: 369.6W
  • 48 port: 739.2W

  Are there plans to release the new ESW 500 switch models increased capacity, enough to supply the full 15.4 to all PoE ports with PoE?

  Hi John - Thank you for your participation in the small community of business support. I talked to our switch product manager and want to share his response.

  / * Style definitions * / table.

  We have taken the conscious decision to deliver PoE as ESW and other switches for small businesses for several reasons:

  • Endpoints PoE more attract a lot less than the 15.4 W maximum power. Most IP phones are below the range of 7W.
  • A typical deployment would most PoE devices connect to a switch.
  • For these reasons, the ESW is not burdened cost with the PoE feature which would not be used most of the time.
  • All ports are still able to PoE you can connect up to 24 devices PoE Switch 24 ports to any point in time, as long as the handset is in the title of the budget.
  • Therefore, given that these products are intended for small business and the price is an important factor, we opted for this approach.

  We do not have a product at full power on all ports in the Cisco Small Business portfolio, except in the arena of 8 channels. Within Cisco, Cisco Catalyst products support this today.

  Thanks again for the question,

  Satellite A85-s107 white screen at startup by using the power of the battery

  When I boot A85-s107 in battery power, it is get booted up in the background, but my screen is empty.
  After that if I connect it to AC power and switch deactivation/activation of the laptop power button, the screen comes back to life.

  There is no problem when I start upward when it is connected to an electrical outlet.
  Battery is fully charged and computer will work off the battery voltage if I remove AC after boootup

  Any suggestions?

  PS:

  also note that when I remove AC and then reconnect I start the computer on two occasions that it does not start the 1st time?

  Don t need to recharge the battery if the AC adapter is plugged ;)
  Try the tips posted by Alex otherwise it of a hardware problem, in my view, there seems to be something wrong with the motherboard...
  In this case, only the replacement could help and it could be a costly affair

  Hello

  Very strange problem
  Have you noticed this problem from the beginning?

  First check if your BIOS is up to date. Updated the BIOS if the new version is available.
  In addition it would be recommended to update the display driver.

  But if two updates don't change this, then I recommend you contact an ASP in your country. It could be a hardware problem.

• No Power Manager on T450s shortcut key?

  I installed a X 220 to a T450s, and I see that there is no shortcut key to select a profile for more power. This seems like a huge oversight. Windows 7 only allows its profiles of power native to be learned from its quick access tools (battery icon in the tray of the taskbar or menu of the Windows key + X). Now if I want to use one of the Lenovo power profiles (which are much more customizable than the native Windows ones), I have to make visible the toolbar of the Lenovo Power Manager in my taskbar so you can double-click it and wait for the application of Power Manager to launch. So I can select a profile, 'apply' the selection and close the application.

  I'm used to switching several times power profiles per day depending on whether I use the laptop on battery on my couch, use it to compile the code on AC power at work, or the half dozen of other situations. Is it possible to install the old app hot-switch selection of profiles of power on this machine and map a keyboard shortcut to this? (I'd be happy to give up some of the unnecessary shortcut keys such as "OS Search" (F10) and 'Switch Window' (F11).

  The executable power profile switcher is C:\Program Files (x 86) \ThinkPad\Utilities\PWMOSDV. EXE.

  PIN in your taskbar or assign a hotkey (for example with AutoHotkey).

• Connection to CVS GigE camera via a network switch

  It is a fundamental and very simple question!

  I intend to connect two GigE cameras to NI CVS-1458RT for an application of Imaging. When I tested the configuration in MAX, I realized that I can connect the cameras directly to the PoE ports, or alternatively, connect the cameras directly to the network switch and in both cases, connect the CVS to my network via its ethernet port. I was wondering if there is a benefit by connecting directly the VCA cameras, if I do not anticipate supply their Poe or if my switch has PoE Betacam.

  Thank you

  Usually, you always want your cameras on dedicated lines, or at least only sharing bandwidth with other devices. The mechanism of transport used by GigE Vision isn't really sharing good bandwidth with other devices. If you only share the bandwidth on a link given with other devices, you can throttle each take only a percentage of the total bandwidth. If you have devices without camera on the link, they don't usually have a mechanism to control the gap inter-frame limitation insofar as GigE vision made which would be necessary for properly sharing the bandwidth without remove the packages of bandwidth.

  If you end up sharing one of the ports for the operation and configuration of the CVS on the network, you will be at the risk of losing image data packets whenever the rest of the traffic is sent. Although there are mechanisms in place to return data, these add latency and jitter to your purchase.

  Hi rmose,

  The software is called power control switch and it is a propriertary for Lenovo K430 software. There are no links available for download again on the thelenovo support site yet, but as far as I KNOW, if you're running in Ultra Mode (red light), the system is already working in Ultra circles and you won't need the power control switch.
