         HP GbE2c Ethernet Blade Switch for c-Class BladeSystem Firmware
                       Customer-Level Release Notes
                              Version 1.0.0
                                5/18/2006

A. Description -

	This is the first release of the HP GbE2c Ethernet Blade Switch 
	for c-Class BladeSystem firmware.


B. Upgrade Requirement -

	Not-Critical.


C. New Features -

	First release.


D. Problems Fixed -

	None.


E. Known Problems -

	1) Performing a "revert apply" CLI command causes ports 17 and 18 (the
	cross-connects) to be marked down.  The ports may be brought back up
	by using the "/oper" command to disable and then enable the ports.

	2) The following SNMP traps are listed in the bt4trap.mib MIB, 
	although the switch does not support them:
		bt4SwCubeInserted
		bt4SwCubeRemoved

	These SNMP traps are supported by the switch (with the same value as
	the equivalent GbE2 traps) but are not listed in the MIB:
		bt4SwTempExceedThreshold
		bt4SwTempReturnThreshold

	3) All SNMP traps are sent with the (GbE2) bt2SwTrapDisplayString
	rather than the (GbE2c) bt4SwTrapDisplayString as defined in the MIB,
	which may cause display issues in some SNMP manager software (e.g.,
	HP-SIM).  The traps may be displayed correctly by loading the GbE2
	MIBs as well, which are available in the GbE2 Management Utilities.

	4) Once the "verbose 0" CLI command is issued, no command prompts
	appear.


F. Notes -

	1) If you are upgrading from a GbE2 p-Class environment, note that 
	the switch cross-connect ports now are disabled by default in the 
	c-Class environment.  Cross-connect ports were enabled by default 
	for p-Class.

	2) Ports 1-18 (downlink and XConnect ports) support the e-Keying 
	mechanism.  The e-Keying feature allows the OnBoard Administration (OA)
	to communicate with the switch, via the I2C interface, as to whether 
	or not there is a port type mismatch.  Depending on that mismatch 
	information, the switch will enable/disable that specific port.  If 
	the port (1-18) is attached to an Ethernet device, depending on what 
	is plugged in to the enclosure, then it is a match so the switch will 
	enable the port.  Otherwise the switch will disable the port to protect
	the port from damage.  The switch will also display the log message 
	"disabled because of a mismatch".  For more details on e-Keying refer 
	to c-Class enclosure documents.

	3) This release will not allow enabling port 19, which is internally 
	connected to the OA network.  Support for this port is planned for a
	future release.

	4) How Bootp works:

		1. Bootp is enabled by default. It is expected that user will 
		configure their BOOTP/DHCP server to issue both IP interface
		and gateway address upon request.

		2. Bootp assigned addresses will override IP interface 1 and 
		gateway 1. 

		3. Bootp assigned addresses will not be saved to the
		configuration dump. 

		4. If user manually configures an IP interface 1 or gateway 1
		through CLI, Bootp will NOT be automatically disabled; but the
		Bootp process will also be re-initiated when the apply is done.
		Note that if Bootp addresses become available, #2 and #3 above
		will still apply; otherwise, the configuration will be updated
		with the user assigned addresses as they become active.

		5. Bootp assigned addresses will be automatically applied while
		user assigned addresses will need to be applied.
 
		6. Bootp can be disabled manually. Any manually configured IP 
		interface and gateway addresses will be saved to the
		configuration.

		NOTES: 
		------
		- When Bootp addresses are assigned, if Bootp is then disabled,
		the current assigned addresses are still active 

		- When going from Bootp enabled/dynamic address assigned, to
		Bootp disabled/static addresses assigned, then doing a revert
		apply takes configuration back to Bootp enabled but the
		addresses must be reassigned by the Bootp server.

		- If Bootp is enabled, user assigned addresses get saved only
		if they haven't been overwritten by a dynamic BootP address yet
		(see #4 above) 

		- User assigned addresses cannot be the same as Bootp assigned 
		addresses.
