Dell Precision R7910 – POST issues

Click here to learn more

  Can anyone help me with the following iDRAC logs of my Dell Precision R7910:

“Normal”,”System Boot”,”Log cleared.”

“Critical”,”System Boot”,”The IO Rsr Right PG voltage is outside of range.”

“Critical”,”System Boot”,”The IO Rsr Left PG voltage is outside of range.”

“Critical”,”System Boot”,”The system board Combined PG voltage is outside of range.”

“Critical”,”System Boot”,”CPU 2 has a thermal trip (over-temperature) event.”

The R7910 has been in storage for the last 6 months as I only recently purchased the following CPU and RAM to get the unit going:

* Intel Xeon E5-2603v3

* 16GB 2Rx4 PC4-2133P RDIMM ECC RAM (Hynix)

Upon first boot the R7910 didn’t POST. I immediately checked the iDRAC and retrieved the above from its logs. I have stripped down the unit to only having one CPU and stick of RAM (no riser cards installed etc) but the R7910 still refuses to POST.  What I find interesting is the “CPU 2 has a thermal trip (over-temperature) event” – 2 CPUs have never been installed in this unit, only a single CPU.

solution: It does sound as though it’s a motherboard issue. What errors do you see when the system is stripped down? Are the riser errors still there? When you stripped the system did you also clear the error logs from the iDRAC before restarting the system? Did you try draining power completely – remove the mains cable and hold in the power button for 30 seconds.

About Product:

The Dell Precision R7910 Workstation features a rack mountable 2U form factor and offers performance, ISV certification, and supports professional graphics cards just like the tower version. A rack workstation also provides a central location to manage the hardware, higher levels of security for your data, and Dell’s outstanding server management tools like iDRAC8 and OpenManage.

Dell’s Precision R7910 rack workstation has a total of seven full-length PCIe 3.0 slots in a two processor configuration. Users can install up to three riser cards and a maximum of two double-width x16 cards. With 600W allocated to graphics support, users can install up to four single width Gen2/Gen3 graphics cards (4 x 150W) or the two double-width cards (2 x 300W) as mentioned above but that does require dual processors. The system also comes with an integrated Network Daughter card but there are many options for enhanced network I/O. Clearly there are options for additional performance and connectivity, including PCIe remote access host cards, optional network daughter cards, and graphics cards. High-end graphics cards including Nvidia Quadro and AMD FirePro are supported. There’s also an optional Nvidia Grid K2a for one to many shared graphics, virtualized workstations. Powering all of this hardware is one, or two redundant hot-pluggable 1100W 90% efficient 80PLUS PSUs.

The system supports Windows 7, 8.1, and 10, in addition to, Red Hat Enterprise Linux and Ubuntu. For workstation virtualization, users can install VMware ESXi or Citrix XenServer. Also supported, are Dell’s outstanding iDRAC with Lifecycle controller, an optional WiFi Link WLAN enables advanced remote management features. Dell’s Precision Optimizer takes the guesswork out of customizing the settings for specific supported programs and helps autotune application setting to maximize performance by up to 121%—free with the system. Patented Reliable Memory Technology (RMT) also helps manage your system by working in conjunction with ECC memory to detect and correct errors in real time. The Dell R7910 rack workstation also supports several security features including an intrusion sensor and data protection, advanced authentication, and malware protection.
