Indications of Malfunction
any of the following indications:
• Error message via OpenArchitect due
to inability to access the registers
within the switch chip, or a failure of
DMA transfers.
• Loss of switch functionality, such as
the inability to forward packets, or
forwarding packets in error.
8 12 Power Supply A power-supply failure will generally result in
lack of boot activity.
3, 6, 12,
13, 16,
17 2, 4, 6,
13, 15 1, 2, 4 Ethernet PHYs
& Transformers An error in the PHY will generally result in
loss of link, or Ethernet data transfer errors
such as Checksum and Frame Alignment.
Note that for ATCA 3.1 Fabric ports, there is
no separate PHY devices or transformers; the
SerDes interface in the switch chips are used
instead.
9 FPGA Most FPGA failures will result in the CPU
failing the boot process.
BOOT ROM If the Boot ROM fails or is not programmed,
there will be no boot activity on the console
port after power up.
Network Cable Network cable failures will result in loss of
link or loss of data packets.
7 IPMI Controller If the IPMI controller is not functioning, the
Ethernet Switch Blade board will not power up
when inserted into a powered-up chassis.
This condition may also result from a failure
within the ATCA Shelf Manager (ShMM) or if
the ShMM determines that the chassis cannot
support the Ethernet Switch Blade.
Testing the FlashROMs
The FlashROMs (device 1 and 2) contain compressed images of the OpenArchitect operating
system. FlashROM device 1 is the primary operating system image. If OpenArchitect has
successfully booted, then FlashROM device 1 is fully operational.
To test FlashROM device 2, set the Ethernet Switch Blade to load the backup image on reboot.
For instructions on temporarily booting from FlashROM device 2, see the section on Booting the
Ethernet Switch Blade User's Guide release 3.2.2j page 177
