About this guide
1 Overview The Brocade 8Gb SAN Switch for HP BladeSystem c-Class (referred to in the rest of this manual as the 8Gb SAN Switch) is a Fibre Channel (FC) switch that supports link speeds of up to 8 Gbps. The 8Gb SAN Switch can operate in a fabric containing multiple switches or as the only switch in a fabric. NOTE: In this document, the Brocade 8Gb SAN Switch refers to those Brocade FC switch modules compatible with the HP BladeSystem c-Class enclosure only.
Component identification Figure 1 and Table 2 identify the physical components of the 8Gb SAN Switch. 1 80 .
NOTE: Refer to Interpreting LED activity, page 34 for complete information on 8Gb SAN Switch LEDs. Internal ports summary Sixteen logical internal ports (numbered 1 through 16) connect sequentially to server bays 1 through 16 with the enclosure midplane. Server bay 1 is connected to Switch Port 1, Server bay 2 is connected to Switch port 2, and so forth. 8Gb SAN Switch redundancy The HP BladeSystem c-Class was engineered as a no-single-point-of-failure bladed solution.
ISL trunking groups If your 8Gb SAN Switch is licensed for interswitch link (ISL) trunking, use the trunking groups available on the switch. The FC ports are numbered from left to right, and are part of the same ISL trunking group. The trunking group consists of the ports shown in Figure 2. NOTE: ISL Trunking is optional software that allows you to create trunking groups of ISLs between adjacent switches.
Supported SFP transceiver options Table 5 through Table 7 lists the only supported SFPs.

Installation and safety considerations The 8Gb SAN Switch installs in the I/O bays in the rear of the HP BladeSystem c-Class enclosure. Refer to the appropriate BladeSystem Enclosure Setup and Installation Guide for specific enclosure requirements. Installing multiple switches If you do not have a DHCP server connected to the OA, install and configure one 8Gb SAN Switch at a time. This is required so that Ethernet IP address conflicts do not occur with duplicate default Ethernet IP addresses.
2. Remove the slot cover (if installed). CAUTION: Properly ground yourself before handling the switch. 3. Press the handle latch to release the installation handle.

Verify that the enclosure is powered on. 2. Verify that the switch is installed. 3.
NOTE: Refer to the HP BladeSystem Onboard Administrator user guide for additional information on EBIPA. Using external DHCP To set the Ethernet IP address using external DHCP: 1. Connect to the active OA with a web browser. 2. Document the DHCP-assigned address by selecting the switch from the OA GUI Rack Overview window. 3. Verify the IP address using a Telnet or SSH login to the switch, or select the switch in the OA GUI Rack Overview window.
9. Identify the interconnect bay number where the switch is installed. At the OA command line, enter: connect interconnect x Where x is the interconnect bay slot where the switch is installed. a. User: admin b. Password: password NOTE: Enter entries as shown, because commands are case sensitive. 10. Or, follow the onscreen prompts to change your password now. 11. The OA will then connect its serial line to the Switch in the specified interconnect bay.
1. Connect the workstation to the Ethernet network containing the OA. If the OA is not on a network, connect directly to the OA/iLO Ethernet port on the active OA. IMPORTANT: Verify that the switch is not being reconfigured from any other connections during the remaining steps. 2. Open a Telnet connection using the IP address set earlier. The login prompt displays when the Telnet connection locates the switch in the network. 3. Enter the user name, using the administrative account admin. 4.

The configupload command copies the switch configuration to the server, making it available for downloading to a replacement switch, if necessary.
3 Managing the 8Gb SAN Switch This chapter provides the following information: • • • • • • • • • Management features, page 31 Maintaining the 8Gb SAN Switch, page 32 Powering on and off, page 33 Interpreting LED activity, page 34 LED patterns, page 34 POST and boot specifications, page 36 Firmware update, page 37 About the reset button, page 37 Replacing a faulty 8Gb SAN Switch Management features The management tools built into the 8Gb SAN Switch (listed in Table 11) can be used to monitor fabric topolog
You can connect a management station to one switch with Ethernet while managing other switches connected to the first switch with FC. To do so, set the FC gateway address of each of the other switches to be managed to the FC IP address of the first switch. The gateway address of the first switch should be set to whatever the gateway address is for the subnet on which the first switch resides. See Table 12.
2. Orient the SFP with the appropriate port. See Figure 7 and Table 13. 80 .C Rev 4-01 0211 07 00 -100 0 40 WH scale: 3/8" = 1" MAC 00 WW 05 1E N 10 :00 35 A2 :1E :05 :00 D6 :D6 :A2 :35 0 23 ADE h BROC Switc N b SA 22 21 20 19 1 18 17 ! 2 set Re 26479a Figure 7 Installing an SFP Table 13 SFP components Item Description 1 bail 2 SFP 3. Insert the SFP into the port until you hear a click. 4. Close the bail.
NOTE: Each time the 8Gb SAN Switch is powered on, its settings are restored to the last saved configuration. Interpreting LED activity You can monitor switch activity and status by checking 8Gb SAN Switch LEDs. There are three possible LED states: no light, a steady light, or a flashing light. The steady lights and flashing lights can be green or amber. The LEDs flash any of these colors during boot, POST, or other diagnostic tests.
Module status LED patterns The system and power LED patterns are shown in Table 15. Table 15 Module Status LED patterns during normal operation LED name Module Status LED color Status of hardware Recommended action No light Switch is off, boot is not complete, or boot failed. Verify that switch is on and completed booting. Steady green Switch is on and functioning. No action required.
LED name LED color Status of hardware Recommended action Fast-flashing amber (on 1/2 second, off 1/2 second) Port is faulty. Check the Port Status LEDs, error log, transceiver, and cable or loopback plug. Clear the error log. Rerun the diagnostics to verify that the error condition is fixed. Alternating green and amber Port is bypassed. Check configuration of FC loop. POST and boot specifications POST is a system check that is performed each time the switch is powered on, rebooted, or reset.
2. Verify that the 8Gb SAN Switch prompt appears on the terminal of a computer workstation connected to the switch. If there is no switch prompt when POST completes, press Enter. If the switch prompt still does not appear, try opening another Telnet session or another management tool. If this is not successful, the 8Gb SAN Switch did not successfully complete POST; contact HP. 3. Review the switch system log for errors.
