I have a Dell R720 with single Processor and 24GB of RAM. It was working fine from the past 1 Year and suddenly started to give KEYBOARD FAILURE error message DURING POST
My IDRAC is also not configured and currently i am unable to go in BIOS.
Every single time i receive STRIKE F1 TO CONTINUE AND F2 FOR SETUP
Is there any solution to this problem...
Does anyone know what the inrush current would be on a PowerEdge R730, I am trying to switch the server remotely and I am getting contact weld on my relays.
Load is minimal, results vary.
Would the inrush be different if both PSU's were powered on at the same time ?
Thankyou
its a PowerEdge R720. When the server is switched nothing is happening only the System ID button is on and inside only one fan position(#4) is spinig even if i swap them.
We have had a few servers fail to stay up and running when just one of the PSUs goes down. We brought one of the problematic PSUs back to our test environment and were able to reproduce the issue for a time being. But the PSU is now functioning correctly. Which leads me to believe there is some sort of firmware issue, as an actually faulty PSU should not magically fix itself.
I know that cold redundancy was a fairly new feature at the time of the R710s release, maybe the PSU thinks its in a cold redundancy state and never ups the power its providing? Is there any way to check the state of the PSU's Cold/Warm Redundancy setting? I know other servers have this available by raw ipmitool commands, but those are undocumented for the public so I don't know how to access them on Dell R710s.
Hi all
I'm having an very strange problem, and was hoping some of you may give me some great ideas to figure out whats going on.
The senario.
My customer has an Dell VRTX with two PowerEdge M520 servers in it.
Both servers are running Windows Server 2012 R2 with HyperV and Cluster.
In total they have 9 VM to handle, and they are doing this very good.
But.....
At some point, for no good reason, on of the host are losing access to the Local network, and because of this, I can't access the server.
Sometimes the host with no LAN access are still having all the VM on it, and these can very well access the LAN, and all of the network, like nothing was happend. But the host is gone.
If I perform an reboot of the host, with the VM, then it comes back online, an can start migration of the other host if needed.
I have just had the above situation (again), but this time the host with no LAN access hold all of the VM, and I couldn't power off the VM in production time.
In the event viewer I saw this:
Event ID: 16945 - MsLbfoSysEvtProvider
MAC Conflict: A port on the virtual switch has the same MAC as one of the underlying team members on Team Nic Microsoft Network Adapter Multiplexor Driver
It's the first time I have seen this error, so I have looked through all of the MAC addresses on the server.
The VM MAC Output:
| VMName | MacAddress |
| ------------------------ | ----------------------------- |
| XXXX-CLPA-A | 00155D017022 |
| XXXX-CLPA-A | 00155D017023 |
| XXXXGT-WDS-TEST-CLIENT | 00155D018117 |
| XXXX-HQDC-A | 00155D017004 |
| XXXX-HQPRON-A | 00155D018103 |
| XXXX-HQPS-A | 00155D017005 |
| XXXX-HQSCALA | 00155D017003 |
| XXXX-WDS-A | 0015AB019F03 |
| XXXX-WDS-B | 00155D017020 |
| XXXX-MGMT | 00155D018102 |
| WDS-CLIENT | 00155D017021 |
As showen here, theres no identical MAC addresses on the VM, so I compared against the Host.
| Connection Name | Physical Address |
| =============== | =============== |
| NIC3 | 18-FB-7B-1B-25-10 |
| NIC2 | 18-FB-7B-1B-25-0F |
| NIC4 | 18-FB-7B-1B-25-11 |
| NIC1 | 18-FB-7B-1B-25-0E |
| LAN TEAM | 18-FB-7B-1B-25-0E |
| vEthernet (LAN | 18-FB-7B-1B-25-0E |
Here I got the same MAC address on 3 interfaces, where two of them are not physical.
In an attemt to fix my problem right now, I have disabled the NIC1 on the host, as this has the MAC addresses there are also used on LAn Team and vEthernet.
And this seems to have help me out for now, because then the host came back to the LAN, and it is possible to find it again on the Cluster Manager.
My question is now, if anyone can tell me whats going on, and why have this happend?
It's not an solution for me, to have the NIC1 disabled, but as an temporary workaround is good at the moment.
Any good ideas?
Thanks

Hello.
I have a Dell R410 Motherboard (without the front panel board), 2x XEON 5570 and 6x 4GB RAM. I hope that I can make them work with a standard ATX Desktop PSU.
There are some points on the motherboard tagged as PWR_BTN. Can I bridge them to power on the board?
I would like to know if this is possible.
Thank you in advance.
Hello,
I got a dell R420 was shipped with single cpu (e5-2420v2) as list here :<Removed>
my st : <Removed>
And I see that there are 2 riser card on the board.
Yesterday I plug in a new one e5-2420v2 (with heatsink and fan) to run dual cpu. The system boot fine, I can now access the OS as normal and can see 24 cores.
But the lcd screen in-front-of the server change from green to orange with warning : HWC2005 system board riser cable or interconnect failure ...
How can I fix this ? is this dangerous ?
Plz show advices.
Thank you and Brs.

I currently have a R420, only one power supply connected to a 220V UPS.
The 2nd power supply, I want to connect to a 120V UPS.
I can not power down this server.
I should be able to simply connect the 120V UPS to the 2nd power supply and all will be fine?
Right?
Hello,
I'm running scientific applications that require large amounts of CPU cores, GPU power and pretty substantial amount of memory. My PE 2950's aren't cutting it without GPUs. I'm considering obtaining an R900 with 16 cores and 64 GB RAM, and installing a couple Tesla M2090 GPU cards for the training and decoding of the applications I run.
My question is if anybody knows if GPUs would work in the R900, as it's not a 12th generation PowerEdge? Mind you these aren't video cards, so I'm not having to worry about disabling the onboard video. These GPUs will run in the 8x PCI-E slots with little performance degradation, and I'm aware that the slots only provide around 25 watts of power and the cards need something like 75 watts. I don't believe the R900 has external PCI-E power connectors (the 6- and 8- pin types) but I was planning on wiring up a separate power supply for that and soldering a harness to bring that into the R900. I'm an engineer and doing such a thing wouldn't be difficult.
I know there is better hardware suited for running multiple GPUs, but the budget is not very big at the moment, and would support obtaining an R900 and two Tesla M2090's, but not ordering a nice new PowerEdge that's actually built for this. I'm used to rigging things to make them work in ways they were not designed for, so I just need to know if anybody is aware if this *could* work. It's a critical project, and the 16 cores + GPU power would allow decoding to run before my hair goes grey.
Thanks!

I have a T430 with a full-size H330 raid controller. It boots to a Linux distribution installed on a disk connected to one of the internal SATA ports. My goal is to connect the H330 directly to a KVM virtual machine via VT-d (IOMMU) passthrough.
I'm discovered that the H330 has a reserved memory range published in the BIOS RMRR table. I woul guess that this reserved memory range is used for management through iDRAC. Unfortunately, because of this reservation, Linux refuses to mapping the H330 into the virtual machine via the IOMMU.
I'm comfortable with losing the ability to manage the H330 through iDRAC, since I'm only going to be using the controller as an HBA within the target VM.
So far, I've tried
The H330 is based on the LSI 3008 controller. Like the H310 (LSI 2008), it may be possible to cross-flash the H330 to LSI firmware for another 3008-based card. However, I have not been successful at erasing the card's flash, thus LSI's flash tool will not recognize the card as supported.
There doesn't seem to be a way to configure this in iDRAC / racadm.
In theory, this would prevent the card from creating any pre-boot registrations in the BIOS, and this shouldn't cause any loss of functionality in the OS since I'm not booting to any drives on the controller. Unfortunately, the Dell BIOS detects the card and forcibly re-enables loading of the Option ROM.
Is IOMMU passthrough of this card supported by Dell? If not, has anyone had any (unsupported) success with the H330 in a similar configuration?
Hi everyone,
I am not being able to create NIC Teaming under a PowerEdge R805 server with 4 Broadcom BCM5708C NIC's with following error:
Has anyone ever experienced the same?
OS is Windows Server 2012 R2 Hyper-V Core.
Cheers,

I am looking at purchasing an off-lease T420 server, that was originally purchased with the cabled hard drive option. I would like to replace the current cage with the cage for the 8 hot-swap cage, then I can connect an 8 drive backplane and add in a H710 RAID controller so I can have RAID storage with more than 4 drives.. I know where to get the 8 drive backplane and the PERC controller, but I haven't found a place to get the cage..
Salve, ci occorrono 8gb di Ram per il server PER515 Service Tag 4zlxxxx, 8 gb suddivisi per tutti i banchi di ram disponibili sul server. Riuscite a contattarmi a <ADMIN NOTE: Email id removed per privacy policy> o al numero <ADMIN NOTE: Phone number removed per privacy policy> abbiamo una certa urgenza Grazie
Hello,
For the last 3 months our R620 server has problems with degraded hard drives. It has RAID 1 (disks 0,1) and RAID 10 (disks 2-7). Each time a new disk is degraded. After the first case, we did a full initialization of arrays. But it didn't help. When one disk is degraded it is rebuilding and the server works stability for some time. If several disks is degraded, the server reboots and displays the error message. One disk is becoming ‘Offline’, other disks are becoming ‘Foreign’.
We can’t find any reason for such unstable work of the server. So logs from iDRAC are in attachment.
The server is under the control of MS Windows Server 2008 R2. We didn’t take any changes in hardware (all components are default).
What can be a reason or what we should check?
Thanks in advance for your help.
Came in this morning to a dead server. There are two power supplies -- one appears to be down. When unplugging and replugging, the light on the power supply goes green and fan kicks on for few seconds, then goes yellow and dies again.
I've pulled the power supply out -- any advice on quick repairs? Or quickly replacing it in the SF bay area?
I have a Poweredge T310 with redundant power supplies. How would I disable the 2nd PSU slot without being able to boot up the server?
I recently set up 2 new R610 servers that I purchased.
Summary:
Both servers 100% same hardware
Both installed with Centos 6.7 64bit
Tested multiple switch ports, same slowness issue.
Both same full duplex / 100mbit speed
Firmware: 1.99 (Build 06)
BIOS 6.4.0
One server is fine on test results around 10Mbps. The problematic server is constantly slow, less than 1MBps. It's obviously noticeable just logging in via ssh as well.

It was replicated on another switch port as well. Same problem. Kind of odd since both server's hardware are exactly the same. I'm thinking it's a setting within the BIOS, but I checked and they both look exact. Maybe NIC drivers need to be updated? If so, how can I do this via Life Controller or even SSH (yum) if possible?

It looks like Dell doesn't sell 2RX4 8GB RAM modules any more. They recommend 2RX8 and 1Rx4 for the R720XD.
Can I mix and match my old 2RX4 with the new 2RX8? I believe the manual says no, but it seemed like an off-hand recommendation, and not a big bold warning.
I have 12 modules installed.
DUAL IN-LINE MEMORY MODULE, 8GB, 1600, 2RX4, 2G, DDR3L, R
My job recently retired this t410 server. It was running with no problems when it was shut down. I was instructed to remove and destroy the hard drives in the system. After that I was allowed to take it home for my own use. I have installed a new sata drive and plugged it into power and an open sata port on the motherboard. When I tried to start the system I get nothing. This version has the single power supply. Power supply light only comes on when you press the test button. System fan goes to full speed but stops when button on power supply is released. Also on control panel lights 1,2, and 4 light up and hard drive powers on and spins up until test button is released. There is one single green light lit on the motherboard when it is plugged in. Other than this I get no reaction when pressing the main power button. Can anyone advise how to proceed to try and get it up and running again.
