Handling BRD Alarms for the Optical Channel Diagnosis Panel in an RH5485

Publication Date:  2015-06-18 Views:  79 Downloads:  0
Issue Description
Figure 1 and Figure 2 shows an optical channel diagnosis panel. The BRD alarm indicator is in the red box. If the BRD alarm indicator is on, the input/output (I/O) board or mainboard is faulty.

Handling Process
1.  Log in to the integrated management module (IMM) to view the IMM event log, and find the following alarm logs:
1499. E --  -- 7/24/2011:16:19:58 -- Fault in slot "No Op ROM Space" on system "SN# 99B5585"

2.  Check whether a Peripheral Component Interconnect Express (PCIe) device is installed in PCIe slot 5. If yes, remove the device and reinstall it in another slot.

3.  After you perform the preceding operations, BRD alarms are cleared. If the IMM continues to report errors, and the network interface card (NIC) integrated by the main board does not support the preboot execution environment (PXE) function, perform the following operations to start the read-only memory (ROM) with the disabled NIC in the Unified Extensible Firmware Interface (UEFI):
  • Choose F1 setup > System Settings > Network > XE Configuration.
  • Select the media access control (MAC) address of the on-board NIC 1.
  • Set PXE Mode to Disabled.
  • Select Save Changes.
  • Select the MAC address of the on-board NIC 2.
  • Set PXE Mode to Disabled.
  • Select Save Changes.
4.  If the BRD alarm indicator is lit, check that the I/O board or main board is faulty based on the actual condition, and replace the faulty component.
Root Cause
1.  If a PCIe device is installed in the PCIe slot 5, and the server is configured with the BR10i RAID controller card, BRD alarms are generated.

2.  If the seven PCIe slots on the server are installed of PCIe devices, BRD alarms are caused.

3.  If no PCIe device is installed in PCIe slot 5, BRD alarms are caused due to the faulty main board or I/O board.
Solution
For the first case, install the PCIe device in other PCIe slots.

For the second case, you are advised to remove those unnecessary PCIe devices.

For the last case, replace the faulty board.

Suggestions
Experience: If BRD alarms are generated for the optical channel diagnosis panel, check that PCIe devices are configured in the seven PCIe slots, a PCIe device is installed in PCIe slot 5, and the RAID controller card is the BR10i card. In addition, check that the NoOp ROM Space alarm is in the IMM log.

Precautions: Do not install PCIe devices in PCIe slot 5.
