Maintenance Button
The Maintenance button is a dual-function momentary switch on the front
panel. Its purpose is to reset the switch module or to place the switch module
in maintenance mode. Maintenance mode sets the IP address to 10.0.0.1 and
provides access to the switch module for maintenance purposes when flash
memory or the resident configuration file is corrupted. Refer to “Recovering a
Switch Module” on page 4-5 for more information about using maintenance
mode.
Resetting a Switch
To reset the switch module, use a pointed tool to momentarily press and
release (less than 2 seconds) the Maintenance button. The switch module will
respond as follows:
1. All switch module LEDs will illuminate, then the System Fault LED
extinguishes leaving only the Input Power LED illuminated.
2. After approximately 1 minute, the power-on self test (POST) begins.
3. When the POST is complete, the Input Power LED is illuminated.
Placing the Switch in Maintenance Mode
To place the switch module in maintenance mode, do the following:
1. Isolate the switch module from the fabric.
2. Press and hold the Maintenance button with a pointed tool for 2–4
seconds.
3. After a few seconds, the POST begins illuminating all switch module
LEDs.
4. When the POST is complete, the switch module LEDs extinguish.
To exit maintenance mode and return to normal operation, momentarily press
and release the Maintenance button to reset the switch module.
The switch module LEDs shown in Figure 1-3 provide status information
about switch module operation. Refer to “External Port LEDs” on page 1-5 for
information about port LEDs.

Fibre Channel Ports
Fibre Channel Ports
The switch module has 6 external Fibre Channel ports through which to
connect to devices or other switches and 10 internal ports connecting to the
server midplane. Each of the external Fibre Channel ports is served by a Small
Form-Factor Pluggable (SFP) optical transceiver and is capable of 1-Gbps,
2-Gbps, or 4-Gbps transmission. SFPs are hot-pluggable. External ports can
self-discover both the port type and transmission speed when connected to
public devices or other switches. The internal ports operate at 1-Gbps or
2-Gbps.
The external ports are named Ext10, Ext11, Ext12, Ext13, Ext14, and Ext15 and
are numbered 10–15 as shown in Figure 1-4. The external port LEDs are
located to the left their respective ports and provide port login and activity
status information.

NOTE: The switch module comes from the factory as a 12-port switch, enabling
external ports 10–13 and internal ports 0–7 . You can upgrade the switch module to
enable the remaining external ports (14, 15) and internal ports (8, 9) through the
purchase of the Port Activation PFE key. Refer to the McDATA Switch Module Management Guide for information about installing a PFE key. For additional McDATA
PFE keys, please contact your McDATA representative or visit the web site at
Each external port has its own Logged-In LED (L) and Activity LED (A) as
shown in Figure 1-6.

The Logged-in LED indicates the logged-in or initialization status of the
connected devices. After successful completion of the POST, the switch
module extinguishes all Logged-In LEDs. Following a successful loop
initialization or port login, the switch module illuminates the corresponding
logged-in LED. This shows that the port is properly connected and able to
communicate with its attached devices. The Logged-In LED remains
illuminated as long as the port is initialized or logged in. If the port
connection is broken or an error occurs that disables the port, the Logged-In
LED will flash. Refer to “Logged-In LED Indications” on page 4-2 for more
information about the Logged-In LED.
The Activity LED indicates that data is passing through the port. Each frame
that the port transmits or receives causes this LED to illuminate for 50
milliseconds. This makes it possible to observe the transmission of a single
frame. When extending credits, the Activity LED for a donor port will reflect
the traffic of the recipient port. Refer to “Distance” on page 2-4 for more
information about extended credits and donor ports.

Fibre Channel Ports
Transceivers
Port Types
Switch modules support SFP optical transceivers for the Fibre Channel ports.
A transceiver converts electrical signals to and from optical laser signals to
transmit and receive data. Duplex fiber optic cables plug into the transceivers
which then connect to the devices. A Fibre Channel port is capable of
transmitting at 1-Gbps, 2-Gbps, or 4-Gbps; however, the transceiver must also
be capable of delivering at these rates.
The SFP transceivers are hot pluggable. This means that you can remove or
install a transceiver while the switch module is operating without harming
the switch module or the transceiver. However, communication with the
connected device will be interrupted. Refer to “Install SFP Transceivers” on
page 3-2 for information about installing and removing SFP optical
transceivers.
Switch modules support generic ports (G_Port, GL_Port), fabric ports
(F_Port, FL_Port), and expansion ports (E_Port). Switch modules come from
the factory with internal ports configured as FL_Ports and external ports
configured as GL_Ports. Generic, fabric, and expansion ports function as
follows:
•A GL_Port self-configures as an FL_Port when connected to a public loop
device, as an F_Port when connected to a single public device, or as an
E_Port when connected to another switch. If the device is a single device
on a loop, the GL_Port will attempt to configure first as an F_Port, then if
that fails, as an FL_Port.
•A G_Port self-configures as an F_Port when connected to a single public
device, or as an E_Port when connected to another switch.
•An FL_Port supports a loop of up to 126 public devices. An FL_Port can
also configure itself during the fabric login process as an F_Port when
connected to a single public device (N_Port).
•An F_Port supports a single public device.
E_Ports enable you to expand the fabric by connecting switch modules with
other switches. Switch modules self-discover all inter-switch connections.
Refer to “Multiple Chassis Fabrics” on page 2-6 for more information about
multiple chassis fabrics. Refer to the McDATA Switch Module Management Guide for information about defining port types.
The Ethernet port shown in Figure 1-7 is an RJ-45 connector that provides a
connection to a management workstation through a 10/100 Base-T Ethernet
cable. A management workstation can be a Windows® or a Linux®
workstation that is used to configure and manage the switch fabric. The
switch through which the fabric is managed is called the fabric management
switch. You can manage the switch module over an Ethernet connection with
the following management tools:
•McDATA Embedded Web Server
•McDATA Element Manager through EFCM
•Command Line Interface (CLI)
•Simple Network Management Protocol (SNMP)
The Ethernet port has two LEDs: the Link Status LED (green) and the Activity
LED (green). The Link Status LED illuminates continuously when an Ethernet
connection has been established. The Activity LED illuminates when data is
being transmitted or received over the Ethernet connection.

Switch Module Management
Switch Module Management
The switch supports the following management tools:
•McDATA Embedded Web Server
•McDATA Element Manager
•Command Line Interface
•Simple Network Management Protocol
•File Transfer Protocol
McDATA Embedded Web Server
McDATA Embedded Web Server is a graphical user interface that provides
both fabric and switch module management functions. Because McDATA
Embedded Web Server resides in the switch firmware, no installation is
needed. You can run one instance of the McDATA Embedded Web Server at a
time by opening the switch IP address with an internet browser. Refer to the
McDATA Switch Module Management Guide for information about the
McDATA Embedded Web Server.
McDATA Element Manager
McDATA Element Manager is a subset of the McDATA Embedded Web
Server and enables you to manage a single switch through EFCM. To open
McDATA Element Manager through EFCM, you must install the Element
Manager (PFE) key on the switch module. For information about McDATA
Element Manager and its capabilities, refer to the McDATA Switch Module Management Guide.
Command Line Interface
The command line interface (CLI) provides monitoring and configuration
functions by which the administrator can manage the fabric and its switches.
The CLI is accessible over an Ethernet connection. Refer to McDATA 4416 Command Line Interface Guide for more information.
Simple Network Management Protocol
SNMP provides monitoring and trap functions for the fabric. The switch
module firmware supports SNMP versions 1 and 2, the Fibre Alliance
Management Information Base (FA-MIB) version 4.0, and the Fabric Element
Management Information Base (FE-MIB) RFC 2837. Traps can be formatted
using SNMP version 1 or 2.
File Transfer Protocol
FTP provides the command line interface for exchanging files between the
switch module and the management workstation. These files include
firmware image files, configuration files, and log files. Refer to the McDATA 4416 Command Line Interface Guide for an example of using FTP to transfer
configuration backup files.
