Safety Guidelines

Follow these safety guidelines to ensure successfu l and saf e operation of the switch:

• The supply circuit, line fusing, and wire size must conform to the electrical rating on the

switch nameplate.

• The ambient air temperature near the switch must not exceed 40 degrees Celsius. This is

particularly important to verify if the switch is installed in a closed or multi-rack assembly.

• The volume of air flow available to the switch must be at least 50 cubic feet per minute,

and all air vents should have a minimum of 1.5 inches of airspace.

Follow these safety guidelines for a rack-mount installation :

• The rack space should be 1U high, 19 inches wide, and 26 inches deep.

• All equipment installed in the rack should have a reliable branch circuit ground

connection. Do not rely on a secondary connection to a branch circuit, such as a power strip.

• The additional weight of the switch should not unbalance the rack or exceed the rack’s

weight limits.

• The rack should be mechanically secured to insure stability in the event of an earthquake.

WARNING For safety reasons, when installing this product in an equipment rack, you must

consider rack stability against tipping. Please refer to the Hewlett-Packard Rack System/E User's Manual provided with the equipment rack to determine rack stability (also available in electronic

format through the HP Web site at

http://www.hp.com/racksolutions/). If the necessary stability is

not achieved, through the placement of additional equipment or ballast, the equipment rack must be anchored to the building structure before operation.

Installing and Configuring the Switch

Saving the System Configuration Files

Upload the switch configuration file for disas ter recovery and keep it in a safe place where it can be easily found. Backing up the configuration after the initial configuration changes and periodically thereafter is strongly recommended.

Backing up the Switch Configuration Settings

FTP must be used on Windows workstations to backup the system configuration. The FTP server must be running before an upload can occur. Use the RSHD service or FTP on a UNIX machine.

Note: The two supplied utilities, RSHD.EXE and CAT.EXE currently do not support uploads for

Windows, only downloads. These utilities are available from the support Web site:

http://www.hp.com/support/fc8B.

1. Verify that the RSHD service (on a UNIX machine) or the FTP service (on a Windows

machine) is running on the host workstation.

2. Log on to the switch as the admin user.

3. At the command line enter the following command:

configUpload "hostIPaddr", "user", "path_filename","password"

where hostIPaddr is the IP address of the host computer, user is the User ID used to log into this computer, path_filename is the path location and filename of the configuration file, and password is the password for the user ID specified. If only configUpload is entered the system prompts you for each parameter.

Example:

switch:admin> configupload Server Name or IP Address [host]: 123.45.678.901 User Name [user]: kelev File Name [config.txt]: switch1 Protocol (RSHD or FTP) [rshd]: ftp Password: upload complete

Next Steps

Specific tasks remain to be completed before the switch is fully operational and manageable in your network with your equipment. These tasks and the associated tools are described in the remaining documents shipped with the product on the Documentation CD. This section provides specific guidance for completing tasks that many users may need to do.

Setting QuickLoop Mode on Ports

The default configuration for a port is fabric mode. QuickLoop is used to connect private hosts to private storage using the Fibre Channel network. A QuickLoop zone, c onnecting two switches, may be used to expand the nu mber of private hosts and storage connected. An entire switch can be set to operate in QuickLoop mode using the qlEnable telnet command. A port on a switch operating in Mixed mode can be set to or removed from QuickLoop using the telnet commands qlPortEnable and qlPortDisable. See the QuickLoop User’s Guide for more details.

Installation and Reference Guide 2-21

Installing and Configuring the Switch

Setting Up Speed Negotiation

There are two methods for co nfiguring the ports o n the FC Entry Sw itch 8B and FC Switch 8B. The port can be set to auto-sensing mode, which allows the port to automatically be configured to the highest speed. Ports can also be set to a fixed speed of either 1 or 2 Gbps.

To display the configuration settings of the ports on a switch, use the portCfgShow. The port speed is displayed as 1G (fixed speed of 1 Gbps), 2G (fixed speed of 2 Gbps), or AN (auto-negotiate). To set the speed level for all the ports on a switch, use the telnet command switchCfgSpeed. To set the speed level for a single port, use the portCfgSpeed.

Depending on your environment you may need to force a port to use a specific speed level. Auto negotiation may not be supported by the device. Check the configuration information for your network components for specific requirements. See the Fabric OS Ref er ence Manual for a detailed command description.

Turning the Switch On and Off

To turn the FC Entry Switch 8B or FC Switch 8B on, connect the power cable to the power connector on the switch and to a power source . The swi tch takes approx imatel y 4.5 mi nutes t o boo t after it is turned on.

To turn the switch off, disconnect the power cable from the power source. Note: Removing all power from the switch triggers a system reset. When power is r e stored, all

devices are returned to the initial state and the switch runs POST, a system check that lasts approximately 2.5 minutes.

POST can be skipped by using the fastboot command. F or more information abo ut this command, refer to the Fabric OS Reference Manual. A fast boot requires approximately two minutes to complete.

Interpreting LED Activity

System activity and status can be determined through the activity of the LEDs on the switch. Note: The LEDs may flash yellow during diagnostic tests, and green, yellow, or orange during

POST. This is normal, and does not indicate a problem unless the LEDs do not display a healthy pattern after POST or the other diagnostic tests are complete.

The orange light may be referred to as “amber” in other documentation.

The switch includes the following LEDs:

• Eight port status LEDs on the SFP media side (above and to the left of each port) to

indicate the status of each port.

• Eight port speed LEDs on the SFP media side (above and to the right of each port) to

indicate the current link speed of each port.

• One switch status LED on the SFP med ia s ide and one on the fan side, to indicate whether

the switch is on and has successfully booted, and whether any of the ports are faulty.

• Two Ethernet port LEDs, one to show lin k speed and one to show link status.
