PXE Boot failed; Link down on DELL EMC XR11

Sbcbcom,

I would probably start with verifying that the correct nic is selected. From the BIOS go to Network Settings and confirm what you have configured under Interface, as seen on page 12 and 13 here. 

Also, what are you seeing under the F12 PXE boot option on boot up, as seen on page 24 of the same document?

Let me know.

Hi Chris,

I have checked network settings already and it is the good PXE device1 settings: embedded NIC1 Port1 Partition 1 with pv4 enabled and the vlan linked to the dhcp ip network. I can see that an IP address is given by dhcp server but after that the link is seen down so the boot failed.

On PXE boot (F12), I can see iPXE i "No boot device available or Operating system detected"

Sbcbcom,

Would you confirm if you have others systems configured for PXE, and if they're working, or is this the initial set up for the first time? 

Is the link on the host and switch, and does DHCP see it?

Lastly, I would just run through and make sure there is;

Connectivity to/from the switch.

Confirm PXE is enabled on the correct nic and port

Determine if the client can receive an ip from the DHCP server

SLI might be a method to confirm on a system with no OS.

Can you update latest Broadcom FW and check the behavior. You can download latest FW from below link

Chris,

This is the first server Dell I have in my conf; I confirm that the DHCP server see it and gives it an ip @. On the IDrac, the link is seen UP . I am trying to boot via redfish,  this way: redfish:// /redfish/v1/Systems/System.Embedded.1

But the link is seen Down during the pxe process. It uses iPXE 1.21.1. 

I have update BroadcomFW as Dell-SHine K told me, but it still fail.

Regards

Hi

I have updated BroadcomFW as you told me, but it still fails.

Hi, Could you please check if there is a setting related to PXE in the BIOS of the network card itself? When you enter the system setup with F2, you should be able to select the device setting and see the settings of the Broadcom network card. I remember there was an option called NIC configuration. I tried to find a screenshot for you, but unfortunately, I couldn't find it. I thought it was as if something had to be fixed in the BIOS settings of the network card itself.

Hi Erman,

I have already configured in System Bios Settings->Network Settings->UEFI PXE Settings -> PXE Device1 Settings-> Embedded Nic1 Port1 Partition1. This is the Nic with the mac @ used for dhcp . This link is shown UP on Idrac dashboard. But not during iPXE boot...

Hello sbcbcom,

Could you provide a picture of the back of the NIC showing the sticker with the part number. It starts with CN-######-…. Need to see that second set of numbers. 

Also please post a picture of the SFP showing part number so I can verify you are using a validated SFP.

Hi Charles,

Here a photo of the sfp 25Gb. Concerning the back of the NIC, there is no access to the back of embedded Nic; I opened the server but no sticker near the embedded nic. I can tell you that the ref of my Dell EMC XR11 is [personal information removed by moderator].

Hello sbcbcom,

I don't see that we have an MikroTik SFP validated.  If you have others you confirmed work you may try one of those.

I would recommend trying a validated SFP. Two are listed below:

Dell NW

SFP28-25G-SR-GEN2 (FEC and no-FEC capable)

CK: 407-BBXU

DPN: W4GPP

Dell NW

SFP28-25G-LR

Tied: 407-BBXY

CK: 407-BBXZ

DPN: 0YR96
