• Connection RPS720 redundant external power supply for DELL 5548

  Hello
  We have two DELL 5548 network switches.
  According to the manual of the switch, we can buy the RPS720 external redundant power supply connection to DELL 5548 current to reach the power supply redundant network switches.

  My question is how to connect this external RPS720 of redundant power to the existing DELL going on?

  I only buy the external RPS720 of redundant power, including the power cable connect to switch existing or I need to buy any item to achieve?

  I try to search on the internet but it is altogether less information regarding on this.

  According to the QuickStart guide, all cables are included. Page 4 ftp.dell.com/.../powerconnect-5524_Setup%20Guide2_en-us.pdf

• Strike F1 key to continue after replacing power supply and pulling the battery system on Poweredge R410

  Hi all

  Recently, I replaced a non redundant power supply on my Dell Poweredge R410. During troubleshooting, I also temporarily removed the battery from the system at any given time.

  The server is back up and running, but when booting, I get:

  "The 4 fan speed can change in installation configuration feature and the option card systems

  Press F1 to continue, F2 to run the configuration utility.

  I think that some BIOS setting reset to remove the battery? I also see a lot of forum posts mentioning the cause of this error is the integrated SATA is connected to anything.

  My hard drives are connected to a PERC via the PCI slot, and the machine has an optical drive. I don't see the existence of the optical drive in omreport.

  Here are a few outlets omreport about SATA settings.

  Integrated SATA controller: ATA
  SATA port 0: Auto
  SATA port 1: Off
  SATA port 2: stop
  SATA port 3: Off
  SATA port 4: Off

  Any advice on how to go about this debugging more?

  Thank you!

  Dave

  Yes, it is possible that the optical drive is defective. Check the logs of equipment. Also enter the system BIOS setup using the F2 key and search for devices listed as unknown.

• ASR9k: Power supply redundancy

  Hey guys

  Another question ASR9k me, this time about power supply redundancy. We have connected all power eight out of the ASR9010 as can be seen in the image. The four connectors to go left to feed, the four connectors on the right to food of B.

  The problem I faced is I lit only a power of Bay (no production again - I had to do a check quick config) and when the DC briefly lost power (I guess that one of the streams for testing), my router is down.

  The question is, what socket on the back goes to Tray 1 internal and that exhaust goes to tray 2? Can I connect the cables as this have feed a diet to 2 power supplies in the status bar of blocks 1 and 2 in tray 2?

  Second question, are there N + N or N + 1 redundancy? I.e. If the chassis is fully equipped 8 of line cards, I then require 4 power supplies (and another 4 for redundancy)? Or I need 7 power supply to power the chassis so I only have 1 for redundancy?

  Concerning

  Tom

  Hi Tom,

  feeder is passive, it has no active components. All active components are on the power supplies. Your scenario would happen if the power fails, then feed B fails. That would be a double fault scenario against which a possible solution is to have a sort of UPS supply.

  Kind regards

• Secondary power supply Cisco 2921, 3925

  Hello!

  I have two routers: 2921 Cisco and Cisco 3925. I want to add blocks of secondary power supply for it.

  What models of power supplies I have to choose?

  Power supplies, already installed on routers:

  2921: PWR-2921-51-AC

  3925: PWR-3900-AC

  If I understand correctly the routers Orient correctly, I can add to 3925 3900-PWR-AC power, but 2921 support system only RPS, not secondary power supply.

  Yes you are right. The 3925 is pretty cut and dry.

  Below of the links for the RPS as it is a bit more complicated. Apparently, you need an adapter for the 2921 (RPS-ADAPTER-2921-51) and get the right cable for the connection with the RPS 2300.

• 3750 x with single power supply

  Didn't know exactly where this post I hope that I am close to.

  I have two 3750 x who were part of a stack, with stacked food.  A switch has two power supplies, the other alone.  How to configure the switch to use only a single power supply.  I always get an error that the battery more redundancy and works in mode of power-sharing.  The battery show power command returns:

• Power supply # power # chassis: off

  Have 4 new UCS chassis in rack. 3 of them have PSU 2 and 4 in a "stopping" State, even if the green light turns on all blocks of 4 power supply into the chassis. All chassis are connected same PDU to the back of the basket, so I know that we have a clean diet.

  I tried adjusting the grid to N + 1 and return to nothing will do. Advice would be useful

  On this version, most of the I2C issues have been corrected, but if the chassis has been assigned for a period of time, your I2C may have been congested for a while.

  To clear the I2C bus, you must reinstall the components that use it... Power supplies, fans, and IOM therefore the recommendation would be to:

  1 - Reinstall each fan and power supply (one at a time and wait 3 minutes before hand) upward once again, move on with the next

  2. Remove subordinate IOM, keep it out of the chassis for 5 minutes, drain all power, put it back and wait it comes back before it.

  Make sure that you have network redundancy configured before you do and if you need help or you don't feel comfortable with the process, contact TAC for assistance.

  If this helps, please rate it... If it solves the problem, please mark it as such for future users to take advantage of it too.

• MSE8000 power supply and current calculation

  Hello

  Understand that there is a calculator tool to determine the power needed for your MSE 8000 chassis and blades.  The results of the calculator are running continuous and current.

  How to determine the power and the current requirement in KT? Struggling to understand and enter the values for the effectiveness of rectifier.

  Thank you

  Best regards

  TF

  Without the guarantee that this info is safe:

  I assume you are using:

  http://www.Cisco.com/en/us/docs/Telepresence/infrastructure/articles/mse_8000_calculate_power_current_requirements_kb_386.shtml

  I think that Valere Power supplies have a return about 90% as the value of the example.

  Suppose that several computer power supplies inefficiant down to 70%, this is what the power

  supply consumes for himself (in other words to warm the room :-)

  BTW, the amount of rectifier modules is what you need to start it, but to be redundant

  you have the double amount, in the example below, it shows 2, but it should be 2 x 2, two for each grid.

  So with 1 x 8050 and 4 x 8510 and 90% you will get something like:

  The calculator results

  The results are the following (values are rounded):

  Requirements	Value
  Power (Watts) CC	1800
  Continuous current (AMPS)	38
  Number of rectifiers of Valère	2

  Results of the calculator for current alternative

  Power supply and current results using the value of rectifier that you entered above, are the following:

  Requirements	Value
  Power (Watts)	2000
  240v PSU current (AMPS)	9
  Current (AMPS) P.S.U. 110V	19

• Bit 4 scripts to get the status of Power Supply

  Hi all

  Uses script xml ILO via cpqlocfg.exe and hponcfg.exe tools to retrieve state information to a server running the ILO 4.

  If I use the web interface, I can get information on the blocks of power and their status of redundancy as shown below - but I can't seem to get this information by using the scripting system. No one knows how to do?

  Thank you

  DAZ

  

  I found it!  In case anyone is wondering, a lot of information on the server is available by querying with the ILO "GET_EMBEDDED_HEALTH" xml tag

  This refers, buried way down in the results, information on power supply (section POWER_SUPPLIES).

  Although he does not seem to ask some information about power supplies, it works!

• G4 MDD power supply Issue

  My MDD was recently stop only two or three minutes after a cold start. The power led lights up, the gray screen with the Apple logo appears with the spinning wheel, but then the machine suddenly loses power as if the power cord was disconnected. These are the things I've already tried:

  1. Removed the PRAM Battery
  2. Disconnected all devices except the keyboard and the monitor
  3. Tried a different power cord

  Start in safe mode did not help. The fans are all running, the red LED lights on the logic board and disk drives seem to work. This could be a power supply issue or a problem with the motherboard and is it possible that I can definitely identify the problem without being able to start the G4? The startup time has been considering more when everything worked last week, would that be a clue? I've owned this machine for more than twelve years and it put to the test so I wonder if it's time to retire him.

  Thanks in advance for any help you can offer!

  Hi, looks a lot like a problem of heat from the CPU, thermal paste is usually good for 5 years or more.

  It runs longer open door?

• 29W power supply will work for iPad 9.7 Pro

  My iPad Pro 9.7 inches provided with a power of 10 watts. It takes about six hours is responsible for the depletion of the layer to be 100% responsible. I would like to be able to do it faster. I noticed that the iPad Pro with a larger screen has a 29 Watt power supply available in the Apple Store. I bought this with the cable Apple to convert USB type C USB 2, which I am connected to my Flash a USB cable.  When I try on my Pro 9.7 inch iPad it charges no faster than six hours. Anyone who has tried using a larger power and they have managed to improve the loading time?

  The smaller iPad Pro does not have lightning speed USB - C compliant connector which has the bigger iPad Pro, so the special USB - C cable and 29W power supply wiil lightning does not work with the smaller iPad Pro to load more quickly.

  Return these back to Apple for a full refund.

  Sorry

• Fan of mid-2010 MP in power supply

  The fan in the power supply of my Mac Pro (mid 2010, OS 10.11.5) began its decent slow in death - intermittent squeaking. I hesitate to pay a few hundred dollars to replace the power supply just when a fan $ 20 will most likely do the trick.

  (1) is that someone can confirm that the fan is replaceable? iFixit.com wasn't much help to answer this question, or for parts. Here's their entry: https://www.ifixit.com/Guide/Mac+Pro+First+Generation+Power+Supply+Unit+Replacem ent/32222

  (2) even in the case that does not know the answer to question (1), I want to give it a shot; can someone point me to a source of parts other than ebay.com, galaxyhp.com or Low End Mac google group? I'm happy to install an after-market fan, unless this is not recommended for a reason any.

  (3) any other suggestions? (If the bearing is not tight, I'm curious to know if I can just pack the her with the fat.)

  Thanks in advance!

  I would try a few drops of Marvel mystery oil, he made fans years beyond their phase of freezing/grinding...

• Power supply on the move...

  What link should I plug my USB 2 plug in my power supply for my MBP 13 '' end 2011...

  None of them. The USB ports on your MacBook Pro are not designed to provide a high current to charge a power supply.

  In case you were keen to use it to power your MacBook Pro, you should know that your MacBook Pro will not charge or run a USB power supply.
