Installing and Removing the Switch Module

This section describes the procedures for installing and removing the Switch Module. The section includes the following topics:

•Installing the Switch Module

•Removing or Replacing the Switch Module

Installing the Switch Module

To install the Switch Module in the IBM BladeCenter, perform the following steps:

Step 1 Select the blade enclosure bay in which to install the Switch Module (Figure 2-1).

Note Figure 2-1 shows the IBM BC-H blade enclosure as an example. Your blade enclosure might be different. For additional information, see the documentation that comes with your blade server or BladeCenter unit.

I/O module bay 9¹

2

I/O module bay 8¹

4

I/O module bay 10¹

¹The bay numbers could be different depending upon your enclosure.

Step 2 Remove the filler module from the selected bay. Store the filler module for future use.

Each I/O-module bay must contain either a Switch Module or a filler module. Therefore, if the removed filler module occupied two bays and is a double-height filler, you must install a single-high filler module in the unused bay.

Note If you are preparing to install the Switch Module in a BladeCenter -HT, make sure the interposer card is installed in the interposer tray. For removal and installation details about the interposer card and tray, see the installation instructions in your documentation for IBM BladeCenter HT Interposer for HS Switch Bay.

Step 3 If you have not already done so, touch the static-protective package that contains the Switch Module to any unpainted metal surface of the blade enclosure or any unpainted metal surface on any other grounded rack component for at least two seconds.

Step 4 Remove the Switch Module from its static-protective package.

Step 5 Move the two release latches to the open position (perpendicular to the switch module).

Step 6 Slide the Switch Module into the selected bay until it stops (Figure 2-2).

Figure 2-2 Installing the Switch Module

Step 7 Push the release latches to the closed position.

After you insert and lock the Switch Module, it turns on, and a power-on self-test (POST) occurs to verify that the unit is operating correctly.

The system power LED blinks green while POST is running and then turns solid green when POST is completed.

Step 8 Confirm that the system power LED is green. See the "Switch Module LEDs" section on page 1-5 for more information about the switch module LEDs.

Step 9 If you have a second switch to install, repeat Step 1 to Step 8.

Step 10 To install the SFP+ transceiver module, see "Installing an SFP+ Transceiver Module" section.

Removing or Replacing the Switch Module

To remove or replace the Switch Module, perform the following procedure:

Step 1 Disconnect any cables from the Switch Module that you are removing.

Step 2 Pull the release latches out from the Switch Module.

The Switch Module moves out of the bay slightly.

Step 3 Slide the Switch Module out of the bay and set it aside.

Step 4 Place either another Switch Module or a filler module in the bay.

Note Complete this step within 1 minute.

Step 5 If you placed a switch module in the bay, reconnect the cables that you disconnected. Attach any additional cables that are required by the Switch Module. If you placed a filler module in the bay, then the replacement is complete.

Configuring the Switch Module with Initial Configurations

After the Switch Module boots up and displays the initial configuration dialog on the serial console connection, you can configure the switch.

To enter the basic configuration parameters, perform the following steps:

Step 1 Telnet to the IP address that you configured in the aMM for MGMT1 of the Switch Module.

•GLC-SX-MM= GE SFP, LC connector SX transceiver D

•GLC-T= 1000BASE-T SFP D

Installing an SFP+ Transceiver Module

When installing an SFP+ transceiver module, observe the following precautions:

•Do not remove the dust plugs from the fiber-optic SFP+ transceiver modules or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module ports and cables from contamination and ambient light.

•Removing and installing an SFP+ module can shorten its useful life. Do not remove and insert any SFP+ module more often than is absolutely necessary.

•To prevent ESD damage, follow your normal board and component handling procedures when connecting cables to the Switch Module and other devices.

To install an SFP+ transceiver module, perform the following steps:

Step 1 Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metal surface on your chassis.

Step 2 Remove the SFP+ transceiver module from its protective packaging.

Note Do not remove the optical bore dust plugs until directed to do so later in the procedure.

Step 3 Remove the 10 Gb Ethernet module slot cover and save.

Step 4 Position the SFP+ transceiver in front of the socket opening.

Caution Verify the correct orientation of your transceiver module before inserting it into the slot. Incorrect insertion can damage the module.

If your transceiver module 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.

Step 5 Insert the SFP+ module into the SFP+ port until you feel the connector latch into place.

Step 6 Press the SFP+ module into the slot firmly with your thumb.

If your transceiver module has a bale clasp, move the clasp to the locked (upright) position.

Step 7 To verify that the SFP+ module is seated and latched properly:

a. Grasp the SFP+ and try to remove it without releasing the latch.

b. If the SFP+ cannot be removed, it is installed and seated properly. If the SFP+ module can be removed, reinsert it and press harder with your thumb, repeating if necessary until it is latched securely into the socket.

Step 8 Remove the dust plugs from the network interface cable LC connectors. Save the dust plugs for future use.

Note Do not remove the SFP+ module plugs until you are ready to install the cables.

Step 9 Remove the dust plugs from the SFP+ transceiver optical bores.

Step 10 Immediately attach the network interface cable LC connector to the SFP+ transceiver.

Removing an SFP+ Transceiver Module

Note The SFP+ transceiver modules are static sensitive devices. Always use an ESD wrist strap or similar individual grounding device when handling SFP+ transceivers or coming in contact with modules.

To remove an SFP+ transceiver module, perform the following steps:

Step 1 Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metal surface on your chassis.

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 Release and remove the SFP+ transceiver module from the socket connector.

If your transceiver module has a bale clasp latch, open the clasp to the unlocked position before pulling the transceiver out of the port.

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 or other protective environment.

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

Connecting Devices to the Ethernet Port

The External Management Port on the Switch Module is a 10/100/1000 Ethernet port that uses standard RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires Category 5, Category 5e, or Category 6 UTP cable. The 10BASE-T traffic can use Category 3 or Category 4 cable.

Caution Category 5e and Category 6 cables can store high levels of static electricity. Always ground the cables to a suitable and safe earth ground before connecting them to the switch module or other devices.

The autonegotiation feature is enabled by default on the External Management Port. At this setting, the port configures itself to operate at the speed of attached devices. If the attached device does not support autonegotiation, you can explicitly set the External Management Port speed and the duplex parameters. To maximize performance, either allow the port to autonegotiate both speed and duplex, or set the port speed and duplex parameters on both ends of the connection.

For simplified cabling, the automatic medium-dependent interface crossover (auto-MDIX) feature is enabled by default on the External Management Port. With auto-MDIX enabled, the port detects the required cable type for copper Ethernet connections and configures the interface accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to the External Management Port, regardless of the type of device on the other end of the connection.

Refer to the Cisco Nexus 4001I and 4005I Switch Module for IBM BladeCenter NX-OS Configuration Guide and the Cisco Nexus 4001I and 4005I Switch Module for IBM BladeCenter NX-OS Command Reference for more information about enabling or disabling autonegotiation, and auto-MDIX.

If auto-MDIX is disabled, use the guidelines in Table 2-1 to select the correct cable for connecting the switch-module 10/100/1000 Ethernet ports to other devices. See the "Cable Specifications" section on page B-2 for cable-pinout descriptions.
