Connecting the Cisco MDS 9396T Switch
The Cisco MDS 9396T switch provides the following types of ports:
• Console port—An RS-232 port that you can use to create a local management connection.
• MGMT 10/100/1000 Ethernet ports—Two Ethernet ports that you can use to access and manage the
switch by IP address, such as through the CLI or Fabric Manager. One of the Ethernet ports can also be
used to export analytic data.
• Fibre Channel ports—Fibre Channel ports that you can use to connect to the SAN, or for in-band
management.
• USB port—USB port that you can use for configuration file backups, and capturing logs to file.

Note
The PC must support VT100 terminal emulation. The terminal emulation software—frequently a PC application
such as HyperTerminal Plus—makes communication between the Cisco MDS 9396T switch and your PC
possible during setup and configuration.
To connect the console port to a PC, follow these steps:
Step 1 Configure the baud rate and character format of the PC terminal emulation program to match the following management
port default characteristics:
• 9600 baud
• 8 data bits
• 1 stop bit
• No parity
Step 2 Connect the supplied RJ-45 to DB-9 female adapter or RJ-45 to DB-25 female adapter (depending on your PC connection)
to the PC serial port.
Step 3 Connect one end of the supplied console cable (a rollover RJ-45 to RJ-45 cable) to the console port. Connect the other
end to the RJ-45 to DB-9 (or RJ-45 to DB-25) adapter at the PC serial port.

Step 3 Connect the other end of the console cable to the supplied RJ-45 to DB-25 adapter.
Step 4 Connect the RJ-45-to-DB-25 adapter to the DB-25 port on the modem.
Step 5 Initialize and configure the modem as specified in the Cisco Fabric Manager Fundamentals Configuration Guide and the
Cisco NX-OS Fundamentals Configuration Guide.
For instructions on how to change these settings, see the Cisco Fabric Manager Fundamentals Configuration
Guide for instructions on how to change these settings.
To connect the console port to a modem after the switch is powered on, follow these steps:
Connecting the Management Port
The autosensing 10/100/1000 Mbps Ethernet management ports are located on the left side of the front panel
(labeled MGMT ETH0 and MGMT ETH1), below the console port. MGMT ETH0 is the default Ethernet
management port (interface mgmt0). This port is used for out-of-band management of the Cisco MDS 9396T
switch and data streaming to remote receivers.
Note
The MGMT ETH1 port is disabled in Cisco MDS NX-OS Release 8.3(1).
Use a modular, RJ-45, straight-through UTP cable to connect the management ports to an external hub or
switch. To connect to a router, use a crossover cable.

Connecting to a Fibre Channel Port
Connecting to a Fibre Channel Port
The Fibre Channel ports in the Cisco MDS 9396T switch are compatible with LC-type fiber-optic SFP+
transceivers and cables (see the Removing and Installing Cables into SFP Transceivers section). You can use
these ports to connect to the SAN or for in-band management. For information about configuring the switch
for in-band management, see the Cisco Fabric Manager Fundamentals Configuration Guide and the Cisco
NX-OS Fundamentals Configuration Guide.
Each transceiver must match the transceiver on the other end of the cable, and the cable must not exceed the
stipulated cable length for reliable communications. SFP+ transceivers can be ordered separately or with the
Cisco MDS 9396T switch.

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams
or view directly with optical instruments. Statement 1051
Note
Wear an ESD wrist strap connected to the chassis when handling transceivers. Keep optical connectors covered
when not in use, and do not touch connector ends. The fiber-optic connectors must be free of dust, oil, and
other contaminants.
Removing and Installing SFP+ Transceivers
Warning
Removing and installing an SFP+ transceiver can shorten its useful life. Do not remove and insert SFP+
transceivers more often than is absolutely necessary. We recommend disconnecting cables before installing
or removing SFP+ transceivers to prevent damage to the cable or transceiver.
Note
Use only Cisco SFP+ transceivers on the Cisco MDS 9396T switch. Each Cisco SFP+ transceiver is encoded
with model information that enables the switch to verify that the SFP+ transceiver meets the requirements for
the switch.
The Cisco MDS 9396T switch supports SFP+ transceivers with the following two types of latching devices:
• Mylar tab latch
• Bale-clasp latch

Maintaining SFP Transceivers and Fiber-Optic Cables
SFP transceivers and fiber-optic cables must be kept clean and dust-free to maintain high signal accuracy and
prevent damage to the connectors. Attenuation (loss of light) is increased by contamination, and it should be
kept below 0.35 dB.
Follow these maintenance guidelines:

Powering Up the Switch
• SFP transceivers are static sensitive. To prevent ESD damage, wear an ESD-preventive wrist strap that
is connected to the chassis while handling transceivers.
• Do not remove and insert a transceiver more often than necessary. Repeated removals and insertions can
shorten its useful life.
• Keep all optical connections covered when not in use. If they become dusty, clean them before using to
prevent dust from scratching the fiber-optic cable ends.
• Do not touch ends of connectors. This prevents fingerprints and other contamination of the connectors.
• Clean regularly; the required frequency of cleaning depends upon the environment. In addition, clean
connectors if they are exposed to dust or accidentally touched. Both wet and dry cleaning techniques can
be effective; refer to your site’s fibre-optic connection cleaning procedures.
• Inspect routinely for dust and damage. If damage is suspected, clean and then inspect fiber ends under
a microscope to determine if damage has occurred.
Powering Up the Switch
Connecting the Cisco MDS 9396T Switch
To power up the switch, you must connect one or two power supplies to AC power sources. The number of
power supplies and power sources used depends on the following conditions:
• If you are using combined power (not using power redundancy), you must connect one power supply to
one AC power source.
• If you are using power supply (n+1) redundancy, you must connect two power supplies to one AC power
source.
• If you are using grid (n+n) redundancy, you must use two power supplies and two AC power sources—you
must connect each power supply to a different power source.
Before you begin
You must have the following before powering up the switch:
• Switch installed in a rack and connected to an earth ground
• Recommended power cable for your nation or region
• AC power source with the required amperage located within reach of the power cable being used
Step 1 Connect a power supply to an AC power source as follows:
1. Using the recommended power cable for your country or region , connect the C19 plug on the power cable to the
power receptacle on the power supply.
2. Connect the other end of the power cable to the AC power source.
3. Verify that the LED is on and green. If the LED is off, check the AC power source circuit breaker to be sure that it
is turned on.
Step 2 If you are using the power supply (n+1) redundancy, you must connect the second power supply as follows:
