CHAPTER
3
Connecting the Cisco MDS 9216
Switch
The Cisco MDS 9216 Switch provides the following types of ports:
• CONSOLE port (Interface Module): An RS-232 port that you can use to
create a local management connection.
• COM1 port (Interface Module): An RS-232 port that you can use to connect
to an external serial communication device such as a modem.
• MGMT 10/100 Ethernet port (Interface Module): An Ethernet port that you
can use to access and manage the switch by IP address, such as through the
CLI or Fabric Manager.
• Fibre Channel ports (Supervisor and Switching Modules): Fibre Channel
ports that you can use to connect to the SAN, or for in-band management.

Caution When running power and data cables in overhead or sub-floor cable trays, we
strongly recommend that power cables and other potential noise sources be
located as far away as practical from network cabling that terminates on Cisco
equipment. In situations where long parallel cable runs cannot be separated by at
least 3.3 ft (1 m), we recommend shielding any potential noise sources by housing
them in a grounded metallic conduit.

Preparing for Network Connections
When preparing your site for network connections to the Cisco MDS 9216
Switch, consider the following for each type of interface, and gather all the
required equipment before connecting the ports:
• Cabling required for each interface type
• Distance limitations for each signal type
• Additional interface equipment required
Connecting to the Console Port
The console port, labeled “Console”, is an RS-232 port with an RJ-45 interface
(see Figure 3-1 on page 3-3). The console port is an asynchronous (async) serial
port; any device connected to this port must be capable of asynchronous
transmission.
We recommend using this port to create a local management connection to set the
IP address and other initial configurationsettings before connecting the switch to
the network for the first time.
Note Connecting the console port to a modem is supported for switches running Cisco
MDS SAN-OS Release 1.2(2a) or later.
Although the console port can be used to connect to a modem, the COM1 port is
recommended for this purpose.

Caution If you do want to connect the console port to a modem, do not connect it while
the switch is booting; connect either before powering the switch on or after the
switch has completed the boot process.
You can use the console port to perform the following functions:
• Configure the Cisco MDS 9500 from the CLI
• Monitor network statistics and errors
• Configure SNMP agent parameters
• Download software updates
Note To connect the console port to a computer terminal, the computer must support
VT100 terminal emulation. The terminal emulation software—frequently an
application such as HyperTerminal or Procomm Plus—makes communication
between the Cisco MDS 9216 Switch and computer possible during setup and
configuration.

Connecting to the COM1 Port
Send documentation comments to mdsfeedback-doc@cisco.com.
To connect the console port to a computer terminal, follow these steps:
Step 1 Configure the terminal emulator program to match the following default port
characteristics: 9600 baud, 8 data bits, 1 stop bit, no parity.
Step 2 Connect the supplied RJ-45 to DB-9 female adapter to the computer serial port.
We recommend using the adapter and cable provided with the switch.
Step 3 Connect the console cable (a rollover RJ-45 to RJ-45 cable) to the console port
(see Figure 3-1) and to the RJ-45 to DB-9 adapter at the computer serial port.
Note For configuration instructions, refer to the Cisco MDS 9000 Family Configuration
Guide.

Note The COM1 port is not supported for connection to a console.
The COM1 port (labeled “COM1”) is an RS-232 port with a DB-9 interface. You
can use it to connect to an external serial communication device such as a modem.
For information about how to turn off hardware flow control, refer to the Cisco
MDS 9000 Family Configuration Guide.
Note Connecting the COM1 port to a modem is supported for switches running Cisco
MDS SAN-OS Release 1.2(1a) or later.
