Znyx Networks bh5700 manual Testing the FlashROMs

Base	ZMC 0	ZMC 1	Hardware	Indications of Malfunction
	#	#	Subsystem
				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,	2, 4, 6,	1, 2, 4	Ethernet PHYs	An error in the PHY will generally result in
13, 16,	13, 15		& Transformers	loss of link, or Ethernet data transfer errors
17				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
