Installing the blade switch

The HP 6125 switches can be installed into the HP BladeSystem c3000 and c7000 enclosures. The installation position in the enclosure in this document is only for illustration. For more information, see HP BladeSystem Enclosure Setup and Installation Guide .

Preparing for installation

WARNING!

The blade switches are Class 1 laser devices. Do not stare into any fiber port when the blade switch has power. The laser light emitted from the optical fiber may hurt your eyes.

CAUTION:

Take ESD-preventive measures to avoid damaging the components. For more information, see HP BladeSystem Enclosure Setup and Installation Guide .

•To avoid any equipment damage or bodily injury caused by improper use, follow the enclosure safety recommendations. For more information, see HP BladeSystem Enclosure Setup and Installation Guide.

•Identify the interconnect bay to install the blade switch. For more information, see HP BladeSystem Enclosure Setup and Installation Guide.

Installing and removing the blade switch

IMPORTANT:

•If the blade switch does not install easily, make sure that it is correctly oriented.

•To prevent dust from entering the system, install the interconnect blank into the interconnect bay after removing the blade switch.

Installing the blade switch

1.Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well grounded.

2.Remove the interconnect blank from the slot.

Keep the removed interconnect blank for future use.

3.Unpack the blade switch.

4.Press the release tab (see callout 1 in Figure 3) and then pull the ejector lever to the open position (see callout 2 in Figure 3).

5.Slide the blade switch into the interconnect bay (see callout 1 in Figure 4) until it touches the backplane.

6.Push the ejector lever to the closed position. (See callout 2 in Figure 4).

Figure 4 Sliding the blade switch into the interconnect bay

7.Verify that the Health LED is green after the blade switch starts up. Otherwise, check the installation.

8.Choose proper cables for the blade switch.

For more information about ports, see "Ports." For more information about cable installation, see "Connecting the blade switch to the network."

Removing the blade switch

1.Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well grounded.

2.Press the release tab to open the ejector lever.

3.Pull the ejector lever outwards slowly to take out the blade switch.

Connecting the blade switch to the network

Connecting the blade switch to the network through twisted pair cables

You can use category-5 or above twisted pair cables to connect the 10/100/1000Base-T ports on your blade switch to the network. These ports use RJ-45 connectors and support MDI/MDI-X auto-sensing.

To connect a 10/100/1000Base-T port to a peer device:

1.Plug one end of a twisted pair cable into the RJ-45 port of the blade switch.

2.Plug the other end of the twisted pair cable into the RJ-45 port of the peer device.

3.Verify the port LED for correct connection. For LED status, see "LEDs."

Connecting the blade switch to the network through optical fibers

WARNING!

To avoid injury to your eyes, do not stare at the optical interfaces and optical fiber connectors when connecting optical fibers.

You can install a transceiver module in a fiber port on the blade switch and then plug the fiber connector to the transceiver module. For more information about installing the transceiver module, see Pluggable SFP[SFP+][XFP] Transceiver Modules Installation Guide.

To install a transceiver module into the port on the blade switch and the peer device:

1.Remove the dust cover of the fiber connector, and clean the end of the fiber connector.

2.Remove the dust plug of the transceiver module, plug one end of the optical fiber into the transceiver module, and plug the other end into the transceiver module in the peer device, as shown in Figure 5.

The transmit port on one end must connect to the receive port on the other end.

3.Verify the port LEDs for correct connection.

For more information about LED status, see "LEDs."

Testing connectivity

After you connect the blade switch to the network, use the ping or tracert command to test network connectivity. For more information about these two commands, see HP 6125 Blade Switch Series Network Management and Monitoring Command Reference.

Accessing the blade switch for the first time

Logging in through the console port

The first time you access the blade switch you must use a console cable (see Figure 6) to connect a console terminal, for example, a PC, to the console port on the blade switch.

A console cable is an 8-core shielded cable, with a crimped RJ-45 connector at one end for connecting to the console port of the blade switch, and a DB-9 female connector at the other end for connecting to the serial port on the console terminal.

Figure 6 Console cable

Setting up the configuration environment

To connect a terminal, for example, a PC, to the blade switch:

1.Plug the DB-9 female connector of the console cable to the serial port of the PC.

2.Plug the RJ-45 connector of the console cable to the console port of the blade switch.

IMPORTANT:

Identify the mark on the console port and make sure that you are connecting to the correct port.

Figure 7 Connecting a console port to a terminal

Setting terminal parameters

To configure and manage the blade switch, you must run a terminal emulator program on the console terminal, for example, a PC. This section uses Windows XP HyperTerminal as an example.

The following are the required terminal settings:

•Bits per second—9,600

•Data bits—8

•Parity—None

•Stop bits—1

•Flow control—None

•Emulation—VT100

To set terminal parameters, for example, on a Windows XP HyperTerminal:

1.Select Start > All Programs > Accessories > Communications > HyperTerminal. The Connection Description dialog box appears.

2.Enter the name of the new connection in the Name field and click OK.

Figure 8 Connection description

3.Select the serial port to be used from the Connect using list, and click OK.
