Problem: Xbar Error/C7010-FAB-1 in Power Down State

The C7010-FAB-1 is in a power down state and these errors appear:

%PLATFORM-3-EJECTOR_STAT_CHANGED: Ejectors' status in slot 13 has changed,
Left Ejector is OPEN, Right Ejector is CLOSE

%PLATFORM-3-EJECTOR_STAT_CHANGED: Ejectors' status in slot 13 has changed,
Left Ejector is OPEN, Right Ejector is OPEN

%PLATFORM-2-XBAR_REMOVE: Xbar 3 removed (Serial number XXX)

Xbar Ports  Module-Type                         Model              Status
---  -----  ----------------------------------- ------------------ ----------
3    0      Fabric Module                       N/A                powered-dn
?
Xbar Power-Status  Reason
---  ------------  ---------------------------
3    powered-dn     failure(powered-down) since maximum number of bringups were exceeded

Alternatively, xbar ASIC errors appear:

%MODULE-4-MOD_WARNING: Module 15 (serial: XXX) reported warning due to
X-bar Interface ASIC Error in device 70 (device error 0xc4600248)

%OC_USD-SLOT15-2-RF_CRC: OC2 received packets with CRC error from MOD 15
through XBAR slot 3/inst 2

Root Cause

This issue is due to either a faulty or bad-seated xbar module, or a bad chassis slot.

Solution

    Check the output of these commands:
        show version
        show module
        show logging
        show logging nvram
        show module internal exception-log
        show module internal event-history
        show core
        show system reset-reason
        show environment | in xbar
        show system internal platform internal event-history xbar X is xbar #
        show system internal xbar-client internal event-history errors
        show system internal xbar all
        show system internal xbar event-history errors
    Perform a hard reseat of the xbar module and check the status.
    If the reseat fails, test xbar in another slot or test the same slot with another xbar module in order to ensure the chassis is fine.
    Replace the faulty hardware based on the tests performed in steps 2 and 3.

就像2楼提供的信息所说的,可能是硬件有问题,按2楼提供的解决方案操作看看要不要更换硬件。
