Connecting the Cisco UCS 6200 Series Fabric Interconnect


The Cisco UCS 6200 Series Fabric Interconnect provides the following types of ports:

RS-232 port—create a local management connection.

Ethernet ports, encrypted and unencrypted—to connect to a LAN.

Fibre Channel ports—connect to a SAN.

This chapter includes the following sections:

Preparing for Network Connections

When preparing your site for network connections to the Cisco UCS 6200 Series Fabric Interconnect, 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


Tip You can save time and confusion when making cabling changes if you make copies of Table C-5 and keep them accurate to your current configuration.


Connecting to the Console Port

The console port is an RS-232 port with an RJ-45 interface. (See Figure 3-1.) 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 configuration settings before connecting the system to the network for the first time.


Caution You can use the console port to connect to a modem. If you do not connect it to a modem, connect it either before powering on the system or after the system has completed the boot process.

The front connector ports are in a 2x2 stacked RJ-45 jack. Figure 3-1 shows a close-up view of the Ethernet connector ports, including the console port.

You can use the console port to perform the following:

Configure the Cisco UCS 6200 Series Fabric Interconnect 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 UCS 6200 Series Fabric Interconnect and a computer possible during setup and configuration.


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 RJ-45 connector of the console cable to the console port (see Figure 3-1) and the DB-9 connector to the computer serial port. Depending on the laptop you use for the initial configuration, you may also want a USB 2.0 to Serial (9-pin) DB-9 RS-232 Adapter Cable.


Note For configuration instructions, see the Cisco UCS Manager CLI Configuration Guide.



Connecting Ports


Caution To prevent an IP address conflict, do not connect the management port to the network until the initial configuration is complete. For configuration instructions, see the Cisco UCS Manager GUI Configuration Guide.

The Ethernet connector port has an RJ-45 interface.

To connect the Ethernet connector port to an external hub, switch, or router, follow these steps:


Step 1 Connect the appropriate modular cable to the Ethernet connector port:

Use modular, RJ-45, straight-through UTP cables to connect the Ethernet connector port to an Ethernet switch port or hub.

Use a cross-over cable to connect to a router interface.

Step 2 Connect the other end of the cable to the device.

Removing a Transceiver

Installing a Transceiver

Use an SFP+ transceiver to connect to an Ethernet or Fibre channel port.


Caution Excessively installing and removing an SFP or SFP+ transceiver can shorten its life. Do not remove and install transceivers unless it is absolutely necessary. We recommend disconnecting cables before installing or removing transceivers to prevent damage to the cable or transceiver.

To install a transceiver, follow these steps:


Step 1 Attach an ESD wrist strap and follow its instructions for use.

Step 2 Remove the dust cover from the port cage.

Step 3 Remove the dust cover from the port end of the transceiver.

Step 4 Insert the transceiver into the port:

If the transceiver has a Mylar tab, position the transceiver with the tab on the bottom, and then gently insert the transceiver into the port until it clicks into place.

If the transceiver has a bale clasp, position the transceiver with the clasp on the bottom, close the clasp by pushing it up over the transceiver, and then gently insert the transceiver into the port until it clicks into place.


Caution If the transceiver does not install easily, ensure that it is correctly positioned and the tab or clasp are in the correct position before continuing.

Note If you cannot install the cable into the transceiver, insert or leave the dust plug in the cable end of the transceiver.

To remove an SFP+ transceiver, follow these steps:


Step 1 Attach an ESD wrist strap and follow its instructions for use.

Step 2 If a cable is installed in the transceiver:

a. Record the cable and port connections for later reference.

b. Press the release latch on the cable, grasp the connector near the connection point, and gently pull the connector from the transceiver.

c. Insert a dust plug into the cable end of the transceiver.


Caution If the transceiver does not remove easily in the next step, push the transceiver completely in and then ensure that the latch is in the correct position before continuing.

Step 3 Remove the transceiver from the port:

If the transceiver has a Mylar tab latch, gently pull the tab straight out (do not twist), and then pull the transceiver out of the port.

If the transceiver has a bale clasp latch, open the clasp by pressing it downwards, and then pull the transceiver out of the port.


Note If you cannot remove the SFP+ transceiver, reseat it by returning the bale clasp to the up position. Press the SFP+ transceiver inward and upward into the cage. Next, lower the bale clasp and pull the SFP+ transceiver straight out with a slight upward lifting force. Be careful not to damage the port cage during this process.


Step 4 Insert a dust cover into the port end of the transceiver and place the transceiver on an antistatic mat or into a static shielding bag if you plan to return it to the factory.

Step 5 If another transceiver is not being installed, protect the optical cage by inserting a clean cover.

Maintaining SFP Transceivers and Fiber-Optic Cables

SFP and 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 should be below 0.35 dB.

Consider the following maintenance guidelines:

Transceivers are static sensitive. To prevent ESD damage, wear an ESD wrist strap that is connected to the chassis.

Do not remove and insert a transceiver more often than is necessary. Repeated removals and installation can shorten its useful life.

Keep all optical connections covered when not in use. If they become dusty, clean before using to prevent dust from scratching the fiber-optic cable ends.

Do not touch ends of connectors to prevent fingerprints and other contamination.

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 fiber-optic cleaning procedures for your site.

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.
