I.	Notes

1. All SANbox2-16 switches with model numbers ending with the letters A
   through G cannot upgrade to the 1.4, or later, firmware release
   without contacting QLogic Technical Support first. Technical Support
   contact information can be found at the end of this document. The
   model number is located on the back of the SANbox2-16 switch.

2. Caution: When downgrading SANbox2 firmware to 1.3.xx, all
   configuration data is lost and a 4-blink code flashes on the
   Heartbeat LED. A backup of the configuration, prior to downgrading
   to 1.3, is recommended. Visit the knowledge base section of our web
   site at http://www.qlogic.com/support/knowledge_base.asp or contact
   QLogic Technical Support for assistance.

3. If you need to downgrade to firmware version 3.0, or to an earlier
   firmware version on a SANbox2 switch, please contact your QLogic
   approved reseller or QLogic Technical Support as noted in the Support
   section of this document.

4. The zoning limits were increased in the 4.1 release. If you downgrade
   your firmware from 4.1 or later to 4.0 with zoning limits that
   exceed the 4.0 limits, you will get alarms stating that the limits
   have been exceeded and an E_Port isolation will occur. To avoid this,
   remove the zoning that exceeds the 4.0 limits prior to downgrading
   the firmware.  Refer to section 3.4.1.4 of the 4.0 Switch Management
   User's Guide for the zoning limits for the 4.0 release.

5. If you have fabrics that cross time zones, please be aware that this
   will cause time stamp differences in the various switch logs.

6. Broadcast is limited to E-Ports and F-Ports on SANbox2-8,
   SANbox2-16, and SANbox2-64 switches.

7. In Firmware 4.2 and later, the IOStreamGuard parameter may be set to
   Auto, Enable, or Disable.  If the parameter is set to Auto and you
   downrev your firmware version to an earlier firmware version, you
   must set the IOStreamGuard parameter appropriately after the downrev
   for each port; otherwise, the storage connected to the ports will
   not be seen.  

8. A switch configuration backup does not archive the primary or 
   secondary secrets for any security groups.  As a result, the
   security secrets need to be reconfigured in Clish after a config
   restore.  Otherwise the restored switch will isolate from the
   fabric due to an invalid attach due to the missing secrets.


II.	Installing the Firmware via telnet

The following procedure should be used, to download Version 5.0.0.31:

After downloading new firmware from QLogic, change directory to the
directory where the new firmware is located.

	ftp to the switch
	login using username images
	enter the following commands:
	> bin
	> put 5.0.0.31.00_xxx (where xxx is mpc for SANbox and x86
				for SANbox2 products)
	> quit
	telnet to the switch
	login using username: admin
	enter the following commands:
	> admin start
	> image unpack 5.0.0.31.00_ xxx (where xxx is mpc for SANbox and
                                x86 for SANbox2)

Refer to the instructions in the Installation Guide listed in the 
Documentation section of these Readme notes for further installation
methods and types of resets to perform to activate this new firmware.


III.	Interoperability

The following interoperability modes are supported for the stated
Brocade, McDATA, and Cisco switch models and firmware versions:

  Cisco switches in their "interop" or "Open" modes:

o	Brocade Silkworm 3200/3800; Firmware supported: v3.1.0,
      v3.1.1c (3800), v3.1.2a (3200), v3.1.1d (3200)
       
o	Brocade Silkworm 3900; Firmware supported: v4.1.0, v4.1.1,
      v4.2.0_rc1,	v4.2.0c, v4.4.0
       
o	Brocade Silkworm 3250; Firmware supported: v4.2.0c

o	McDATA ES-3232, McDATA 4300, McDATA 4500, McDATA ED6064, McDATA
      ED6140; Firmware supported: 06.01.00.09, 06.01.00.18, 06.02.00.22,
      07.00.00

- InteropMode set to Interop_1 supports Brocade switches in "Native"
  mode:

o	Brocade Silkworm 3200/3800; Firmware supported: v3.1.0, v3.1.1b,
      v3.1.1c (3800), v3.1.2a (3200), v3.1.1.d (3200)

o	Brocade Silkworm 3900; Firmware supported: v4.1.0, v4.1.1a,
      v4.2.0_rc1,	v4.2.0c, v4.4.0
       
o	Brocade Silkworm 3250; Firmware supported: v4.2.0c

For information regarding configuration settings necessary for
InteropMode set to Interop_1, refer to the FAQ at the following link:

http://www.qlogic.com/cgi-bin/faq_display.pl?faq=switch/sw_sb2_036.html


Known Issues with Brocade/QLogic operation that are not documented in
the Interoperability Guide (see note below):

- In a mixed QLogic, McDATA, Brocade fabric, using McDATAs GUI to take
  the McDATA switch offline/online sometimes caused an ISL failure
  between QLogic switches and Brocade switches. When this occurs, the 
  Brocade loop initialization code will continuously loop.

- Brocade BB credit negotiation does not work properly. Flow control 
  errors are reported during an E_Port offline/online. This problem is
  fixed in Brocade switch firmware v3.1.0 and later.

- Connecting a QLogic switch to a Brocade 3900 switch via a GL port will
  cause the Brocade switch to become inoperable. To work around this
  issue, change the QLogic port to a G port.  The Brocade 3900 switch
  demonstrates this issue with other non-QLogic switches. 

- With InteropMode set to Standard (FC-SW-2) and connected to a Brocade
  3250 switch (4.2.0c firmware), Brocade BB credit negotiation does not
  work properly while traffic is running if the non-Brocade switch has
  fewer BB credits than the Brocade 3250 switch.  To resolve this issue
  reconfigure the BB credits on the Brocade switch to match those on
  the non-Brocade switch.

- With InteropMode set to Standard (FC-SW-2) and connected to a Brocade
  3200/3800 switch (3.1.2a firmware), zone merges or zone changes
  involving 400 or more WWPN zone members can take five minutes or
  longer to complete.

- With InteropMode set to Standard (FC-SW-2) and connected to a Brocade
  3200/3800 switch (3.1.0 or later firmware) and a Brocade 3900 switch
  (4.1.0 firmware or later), the following issues occur:

o 	When zone merges with a full zone database occur, the full zone
      protocol bit is not enabled.  This is not in compliance with the
      FC-SW-2 specification. There is no current impact to the customer.

o 	If a cfgsave command is issued from the Brocade switch for a zone
      change with a full zone database, a non-standard value is included
      in the save command payload.  The QLogic switch will reject the
      command which causes the save to fail.  A workaround is to issue a
      cfgenable command from the Brocade switch which activates and
      saves the zone change.


Known Issues with McDATA/QLogic operation that are not documented in the 
Interoperability Guide (see note below):

- McDATAs SANpilot, and command line interface, do not display devices 
  attached to the QLogic switch. A workaround is to use their EFCM tool,
  v7.0 or earlier.

- When you display the IP address of a McDATA switch using either the 
  "show fabric" clish command or the SANsurfer Switch Manager, the IP
  address will be displayed as 0.0.0.0.

- Fabric Binding is not supported in McData switches operating in Open
  Fabric mode.


Known Issues with Cisco/QLogic operation that are not documented in the 
Interoperability Guide (see note below):

- None.
