Chapter  
Introducing the SAN I/O Module  
1
The Brocade 4424 is a 24-port Fibre Channel module with 8 external ports and 16 internal ports  
designed for installation in a Dell PowerEdge M1000e Blade Server Enclosure. The product ships  
with 12 ports enabled and can be upgraded to 24 ports through Ports on Demand (POD) licensing.  
These ports support link speeds up to 4Gbit/sec.  
Dual function and access gateway configurations  
The SAN I/O Module ships in one of two configurations:  
Dual Function configuration. In this configuration, the SAN I/O Module operates in Standard  
Full Fabric Switch mode by default. The module can also operate in Access Gateway mode.  
Access Gateway configuration. In this configuration the SAN I/O Module operates exclusively in  
Access Gateway mode. Access Gateway simplifies SAN deployment by using NPIV. NPIV  
provides Fibre Channel switch functions that improve SAN I/O Module scalability,  
manageability, and interoperability. For more information on Access Gateway, refer to the  
following:  
-
-
-
For a list of SAN I/O Module F_Ports mapped to N_Ports in the SAN I/O Module as shipped  
For general information and details on using Access Gateway, refer to the Brocade Access  
Gateway Administrator’s Guide.  
Since Access Gateway relies on NPIV technology for its connection to the edge fabric you  
may have to prepare the edge fabric before connecting it to Access Gateway. Please refer  
to the SAN TECH NOTE – Preparing to Install the Brocade Access Gateway for specific  
instructions.  
NOTE  
When shipped in Access Gateway configuration, a Switch (Fabric) license is required to operate the  
module in Standard Full Fabric Switch mode.  
NOTE  
Access Gateway cannot be connected directly into an array; it requires a fabric to support NPIV.  
Determining module configuration  
The factory configuration type is identified by the part number on a label attached to the module.  
Refer to Figure 3 on page 5 for label location.  
If the part number is DL-4424-0001, then the SAN I/O Module is configured in Standard Full  
Fabric Switch mode. Note that Full Fabric Switch mode is the default setting when shipped  
from the factory. Access Gateway mode can also be enabled on this module.

trunking group. Ports that can be used within the same trunking group are color-coded on the SAN  
I/O Module’s port side for easy identification.  
The external ports are divided into two equal groups:  
1. Ports 17, 18, 19, and 20  
2. Ports 21, 22, 23, and 0  
NOTE  
Only the external ports are available for trunking.  
The external ports can form 2-port trunks, 3-port trunks, or a 4-port trunk. For details about  
Brocade ISL Trunking, see the Brocade Fabric OS Procedures Guide.

It is recommended that you set the IP address using the Blade Server Enclosure CMC GUI  
application because this enables centralized management of the SAN I/O Module.  
Using the SAN I/O Module CLI to set the IP address  
Use the following tasks to change the IP address on the SAN I/O Module using the Module’s CLI.  
Task 1: Establish a terminal session with the SAN I/O Module  
Use these steps to establish a terminal emulation session between the SAN I/O Module and a  
Blade Server Enclosure management workstation used for managing the I/O Module. Once this  
session is established, you can log into the Module and use its CLI commands to manage the  
module.  
1. Connect a serial cable between the serial console port on the SAN I/O Module and a Blade  
Server Enclosure management workstation that can establish a terminal emulation session  
with the SAN I/O Module. For instructions, refer to Configuration Guide for your Blade Server  
enclosure.  
2. Disable any serial communication programs that are running on the workstation.  
3. Using a terminal emulator application (such as HyperTerminal on a PC or TERM in a LINUX or  
UNIX environment), establish a terminal session to the SAN I/O Module from the management  
workstation. You will use this connection if you want to reset the module’s IP address using CLI  
commands and perform other configuration tasks.  
For Windows 95, 98, 2000, XP or NT  
a. Click Start and select Programs -> Accessories -> Communications.  
b. Select Hyperterminal and enter a name for the connection.

Connecting the SAN I/O Module to the Ethernet network  
2
Connecting the SAN I/O Module to the Ethernet network  
Once you have successfully set the appropriate IP address of the SAN I/O Module, you can  
establish an Ethernet connection through the Chassis Management Controller (CMC) to a remote  
management workstation for any additional configuration. The management workstation must be  
on the same Ethernet subnet as the CMC.  
NOTE  
Ensure that the SAN I/O Module is not being modified from any other connection until configuration  
is complete.  
Connecting the SAN I/O Module to the fabric  
NOTE  
Refer to “Cabling guidelines” on page 8 before beginning the following procedure.  
Before beginning the following steps, determine whether the SAN I/O Module is in Access Gateway  
or Full Fabric Switch mode. This affects the configuration process. Using the SAN I/O Module CLI,  
you can enter the ag ––modeShow command to determine the current operating mode.  
1. If the SAN I/O Module is in Full Fabric Switch mode, continue with step 2 and step 3. If the  
Module is in Access Gateway Mode, go on to step 4.  
2. Log onto the SAN I/O Module through a Telnet connection, using the admin account.  
3. Modify the domain ID if required using SAN I/O Module CLI commands.  
The default domain ID is 1. If the SAN I/O Module is not powered on until after it is connected  
to the fabric and the default domain ID is already in use, the domain ID for the new SAN I/O  
Module is automatically reset to a unique value. If the SAN I/O Module is connected to the  
fabric after it has been powered on and the default domain ID is already in use, the fabric  
segments.  
To find the domain IDs that are currently in use, run the fabricShow command on another SAN  
I/O Module in the fabric. Identify an unused domain ID:  
a. Disable the SAN I/O Module being configured using the switchDisable command.  
b. Enter the configure command.  
The command prompts display sequentially. Enter a new value or press Enter to accept  
each default value. The SAN I/O Module now has a unique domain ID and can join the  
fabric. Following is an example of command output.

c. Re-enable the SAN I/O Module by entering the switchEnable command.  
NOTE  
It could take a short time (typically a few seconds, but sometimes a little longer) for the newly  
added SAN I/O Module to appear in the fabric display with its newly assigned domain ID.  
4. If you need to install SFP transceivers, install them in the external Fibre Channel ports as  
required.  
a. Remove the dust plugs from the ports to be used.  
b. If necessary, remove the end caps from the SFP.  
c. Orient the transceiver correctly and insert it into a port until it is firmly seated and the  
latching mechanism clicks.  
For instructions specific to the type of transceiver, refer to the transceiver manufacturer’s  
documentation.  
d. Repeat substeps a, b, and c for the remaining ports, as required.  
5. Connect the cables to the transceivers.  
The transceivers are keyed to ensure correct orientation. If a transceiver does not install easily,  
ensure that it is correctly oriented and that the end caps have been removed. The cables used  
in trunking groups must meet specific requirements. For a list of these requirements, see the  
Fabric OS Administrator’s Guide.  
ATTENTION  
A cable should not be bent to a radius less than 5.08 cm (2 inches) under full tensile load and 3.048  
cm (1.2 inches) with no tensile load.

7. Verify the correct operation of the SAN I/O Module by typing the switchShow command from  
the workstation.  
This command provides information about SAN I/O Module and port status.  
8. Verify the correct operation of the SAN I/O Module in the fabric by typing the fabricShow CLI  
command from the workstation.  
9. Back up the SAN I/O Module configuration to an FTP server by typing the configUpload  
command and following the prompts.  
This command uploads the SAN I/O Module configuration to the server, making it available for  
downloading to a replacement SAN I/O Module if necessary. Brocade recommends backing up  
the configuration on a regular basis to ensure that a complete configuration is available for  
downloading to a replacement SAN I/O Module.  
For specific instructions about how to back up the configuration, see the Fabric OS  
Administrator’s Guide. The switchShow, fabricShow, and configUpload commands are  
described in detail in the Fabric OS Command Reference Manual.  
Changing from Fabric Switch mode to Access Gateway mode  
If your SAN I/O Module can run in Dual Function mode and is currently configured in Standard Full  
Fabric Switch mode you can enable Access Gateway mode using the following instructions. You can  
log into the SAN I/O Module and enable Access Gateway mode using either Web Tools or the SAN  
I/O Module command line interface (CLI).  
Notes  
The module ships from the factory in either Access Gateway or Dual Function mode. In Dual  
Function mode, you can configure the module for either Access Gateway Mode or Full Fabric  
Switch mode without an additional license. The module is enabled for Full Fabric Switch mode  
as the default. If the module comes configured in Access Gateway mode, you will need an  
upgrade license to change to Dual Function mode.  
Enabling Access Gateway mode is a disruptive process because the switch is disabled and  
rebooted.Once you enable the SAN I/O Module in Access Gateway mode, only a limited subset  
of Fabric OS commands are available and all fabric-related service requests are forwarded to  
the fabric switches. See the Access Gateway Administrator’s Guide for more information.  
When you enable Access Gateway mode some fabric information is erased, such as the zone  
and security databases. To recover the information save the switch configuration before  
enabling Access Gateway mode.

The SAN I/O Module automatically reboots and comes back online in Access Gateway mode  
using a factory default F_Port to N_Port mapping. You can enter the ag ––modeShow  
command to ensure that the module is in Access Gateway mode. See the Access Gateway  
Administrator’s Guide for more detailed configuration information.  
You can also enter the ag ––mapshow command to display the F_Port to N_Port mapping.  
Enter ag ––help command to display a list of all Access Gateway actions.  
Changing from Access Gateway Mode to Fabric Switch Mode  
If your SAN I/O Module can run in Dual Function mode and is currently configured in Access  
Gateway mode, you can enable the module for Standard Full Fabric Switch mode by disabling  
Access Gateway mode. When you do this, the module automatically reboots in Fabric Switch mode.  
For complete instructions on disabling Access Gateway Mode using the CLI and joining the switch  
to the fabric, refer to the “Disabling Access Gateway Mode” section in the Access Gateway  
Administrator’s Guide.  
Notes  
A license is required for Dual Function Mode, which allows you to switch between Access  
Gateway and Standard Full Fabric Switch Mode. If your SAN I/O Module was shipped in Access  
Gateway Mode, you cannot switch to Fabric Switch Mode without this license.  
You can also use the CLI licenseshow command to determine whether the module is Dual  
Function (Switch), or Access Gateway. This command displays current license keys, along with  
a list of licensed products enabled by these keys. A Dual Function (Switch) module should have  
a “Fabric license” in the command output  
Disabling Access Gateway mode is disruptive because the switch is disabled and rebooted.  
Always back up the current configuration before enabling or disabling Access Gateway mode.  
Enabling Access Gateway mode clears the security and zone databases. Disabling Access  
Gateway mode clears the F_Port to N_Port mapping.  
Activating Ports on Demand (POD)  
Ports on Demand (POD) licensing allows you to enable up to 24 ports from the initial 12 ports. Add  
optional POD licenses using either Brocade Web Tools or a Telnet connection; do not use the Blade  
Server Enclosure CMC software.  
Ports on Demand is ready to be unlocked in the SAN I/O Module firmware. A POD license might be  
supplied with SAN I/O Module software, or you can purchase the license separately from your SAN  
I/O Module vendor, who will provide you with a key to unlock it.  
Once you have installed the license keys, you must enable the ports. You can do so without  
disrupting SAN I/O Module operation, or alternatively, you can disable and re-enable the SAN I/O  
Module to activate all ports.  
If you remove a POD License, ports that were enabled by that license are disabled.

or before connecting to an existing SAN.  
For SAN I/O Modules already connected to existing storage networks:  
1. Add the POD license using Web Tools or CLI.  
2. Enable each newly licensed port using Web Tools or CLI.  
NOTE  
This method is non-disruptive to existing servers and storage connecting to SAN I/O Module.  
For new SAN I/O Module installations, perform the following before connecting to an existing SAN.  
ATTENTION  
Do not use this method if the SAN I/O Module is operating in an existing SAN because traffic will be  
disrupted.  
1. Disable the SAN I/O Module.  
NOTE  
If Secure Fabric OS (Secure FOS) is enabled, you cannot use Telnet or SSH to disable the  
module. For details about using Web Tools, refer to the Web Tools Administrator’s Guide. For  
details about the CLI, see the Fabric OS Command Reference Manual.  
2. Add the POD license using Web Tools or the CLI.  
3. Enable the SAN I/O Module using Web Tools or CLI. When the SAN I/O Module is enabled, the  
newly-added POD ports are also enabled.  
Connecting to the SAN I/O Module Using Web Tools  
Complete the following steps to connect to the SAN I/O Module using Web Tools.  
1. On the management console, open a Web browser such as Internet Explorer.  
The Web browser must be connected to the same network as the SAN I/O Module.

Chapter  
Operating the SAN I/O Module  
3
This chapter describes the operation and interoperability of the SAN I/O Module.  
Interoperability  
The SAN I/O Module supports interoperability for the following functions:  
link initialization  
soft WWN zoning  
SNMP facilities  
principal SAN I/O Module  
selection  
translative mode (private target support on fabrics)  
trunking (between two Brocade switches)  
Advanced Performance Monitoring  
routing (FSPF)  
Simple Name Service  
state change notification  
Port negotiation  
The SAN I/O Module has been designed to be highly interoperable. It supports 1 Gbit/sec, 2  
Gbit/sec, and 4 Gbit/sec transmit and receive rates with autonegotiation. The actual data signaling  
rate used on a port is automatically sensed and set to the rate supported by the device or devices  
attached to the port.  
If the SAN I/O Module is connected to a device, but is unable to negotiate the signaling rate, the  
operator can manually set the speed of each port through the management interfaces.  
The SAN I/O Module is compliant with current Fibre Channel standards, including most  
current-generation switch N_Ports, NL_Ports, and E_Ports as well as host adapters, Redundant  
Array of Independent Disks (RAID) storage devices, hubs, Fibre-SCSI bridge devices, and older  
switch families.

Operating system support  
Brocade Fabric OS has no specific host OS dependencies. The Fabric OS in the switches allows for  
any Fibre Channel-compliant device to attach to switches as long as it conforms to the standards  
for device login, name service, and related Fibre Channel features. The operating systems listed in  
Table 2 are for the host machine running Brocade management applications outside the Fabric OS,  
such as Fabric Manager and Enterprise Fabric Connectivity Manager (EFCM). For the latest  
information on operating system support for these applications, refer to the latest released  
versions of Fabric Manager and EFCM documentation.

Accessing the SAN I/O Module  
The SAN I/O Module is managed as a single element. It has a single IP address and appears as a  
separate entity to the Telnet protocol and the Simple Network Management Protocol (SNMP).  
When SNMP devices send SNMP messages to a management console running SAN management  
software, the information is stored in a Management Information Base (MIB). The Brocade 4424  
Fabric OS 4.4.1 supports the FibreAlliance Fibre Channel Management (FCMGMT) MIBs, allowing  
the provision of needed information to a SAN administrator.  
In addition, the Brocade Fabric Access Layer (API) and the Storage Management Initiative (SMI)  
provide facilities for the discovery and management of physical and logical elements in a SAN.  
Using the Fabric Access interface to the Fabric OS, a client application can retrieve information and  
modify the configuration of Brocade switches in the fabric.

Secure Telnet access is available using Secure Shell (SSH), a network security protocol for secure  
remote login and other secure network services over an insecure network.  
Brocade Web Tools management is available through a secure browser using Secure Sockets Layer  
(SSL). The SSL security protocol provides data encryption, server authentication, message integrity,  
and optional client authentication for a TCP/IP connection. Because SSL is built into all major  
browsers and Web servers, installing a digital certificate enables the SSL capabilities.  
Interpreting POST results  
The power-on self test (POST) system check is performed each time the SAN I/O Module is powered  
on, rebooted, or reset.

During POST, the LEDs are activated in various indicator patterns.  
Perform the following steps to determine POST completion status.  
1. Verify that the LEDs on the SAN I/O Module indicate a healthy SAN I/O Module. LED patterns  
are described in “Interpreting LED activity,” next.  
If one or more LEDs do not display a healthy state, verify that the LEDs are not set to beacon.  
Use the SAN I/O Module CLI switchShow command or Web Tools to verify the LED state. For  
information about how to turn beaconing on and off, see the Fabric OS Administrator’s Guide  
or the Web Tools Administrator’s Guide.  
2. Use the Blade Server Enclosure’s Chassis Management Controller (CMC) GUI to verify that the  
SAN I/O Module is working correctly.  
For details, refer to the Hardware Owner’s Manual for the Blade Server Enclosure.  
3. Review the system log for errors.  
Any errors detected during POST are written to the system log. Access this log through the  
Module’s CLI errShow command. For information about this command, see the Fabric OS  
Command Reference Manual. For information about error messages, see the Fabric OS  
System Error Message Reference Manual.

Locating the serial number  
Before contacting service support, be sure to obtain the module’s serial number. Use one of these  
methods to locate the number:  
Use the CLI and enter the ChassisShow command. The SAN I/O Module serial number is  
displayed along with other data.  
Locate the serial number on the label attached to the SAN I/O Module. Refer to Figure 3 on  
page 5 for location.  
Removing and replacing the SAN I/O Module  
Complete the following steps to remove and replace a failed SAN I/O Module.  
NOTE  
Before beginning this procedure, ensure that you have a replacement SAN I/O Module or filler panel  
available because you do not want to leave the slot on the Blade Server Enclosure open for an  
extended period of time. The slot must be filled with either a replacement SAN I/O Module or a filler  
panel to maintain proper airflow.  
1. Back up the SAN I/O Module configuration to an FTP server by using the Module’s  
configUpload CLI command and following the prompts.  
This command uploads the SAN I/O Module configuration to the server, making it available for  
downloading to a replacement SAN I/O Module if necessary. It is recommended to back up the  
configuration on a regular basis to ensure that a complete configuration is available for  
downloading to a replacement SAN I/O Module.  
2. Stop all SAN activity requiring the ports used by the SAN I/O Module.  
For details about port management, refer to your Blade Server Enclosure Hardware Owner’s  
Manual. Verify that there is no activity by viewing the SAN I/O Module LEDs. For details about  
LED activity on the SAN I/O Module, see “Interpreting LED activity” on page 22.  
3. Remove all cables from the SFP modules.  
4. Remove the SFP modules according to the manufacturer’s instructions.  
Figure 6 on page 24 details the generic process for removing an SFP from a port.

Appendix  
SAN I/O Module specifications  
A
This appendix provides product specifications and regulatory compliance as a handy reference.  
Access Gateway Mode default port mapping  
The 4424 SAN I/O Module can contain 24 total ports. Of these, F_Ports are ports 1-16 and N_Ports  
are ports 0 and 17-23.  
In Access Gateway mode, the SAN I/O Module F_Ports are mapped to N_Ports. This following lists  
the factory-default F_Port to N_Port mapping for Access Gateway mode. Since the SAN I/O Module  
is shipped with Dynamic Ports on Demand (DPOD) enabled, any out of the 24 ports can be  
enabled. Therefore this mapping applies for 12 active ports or, if POD licensing is enabled, for 24  
ports. For more information on changing port mapping and managing ports in Access Gateway  
Mode, refer to the Access Gateway Administrator’s Guide.
