1 PRODUCT DESCRIPTION Product Description Overview Features Front Panel, Model S10 Short-Wave Hub Front Panel, Model L10 Long-Wave Hub Rear Panel, Short-Wave and Long-Wave Hubs Supported Topologies 11
Overview The Hewlett-Packard SureStore E hub, short-wave model S10 and long-wave model L10, is a full-duplex, 1063-megabit-per-second hub. It increases loop reliability, number of loop connections, and distances between server and mass storage devices in a Fibre Channel Arbitrated Loop. The hub’s port detection and bypass circuitry dynamically detects and bypasses a failed node on the loop.
Features HP SureStore E hubs provide the following features: Short-wave hub (model S10): 10 non-Open Fibre Control (non-OFC) short-wave optical transceivers • Long-wave hub (model L10): nine non-OFC, short-wave optical transceivers and one non-OFC, long-wave optical transceiver • Local retime and regeneration of transmit signals to prevent accumulation of jitter and improve the signal • Reliable, automatic bypass of failed nodes; dynamic recognition of newly added or removed nodes, with a controller i
Front Panel, Model S10 Short-Wave Hub The front panel contains LEDs for monitoring power, fault, and port status. The RS-232 port is provided to configure and troubleshoot the hub and to upgrade its firmware. The 10Base-T port provides an ethernet connection if you choose to manage the hub with Fibre Channel Manager. The Reset button resets the internal control microprocessor of the hub. Pushing the Reset button also forces loop initialization on all devices in the loop.
Front Panel, Model L10 Long-Wave Hub Product Description The front panel contains LEDs for monitoring power, fault, and port status. The long-wave port is between port 9 and the 10Base-T port. The RS-232 port is provided to configure and troubleshoot the hub and to upgrade its firmware. The 10Base-T port provides an ethernet connection if you choose to manage the hub with Fibre Channel Manager. The Reset button resets the internal control microprocessor of the hub.
Rear Panel, Short-Wave and Long-Wave Hubs Three fans, located in a customer-replaceable module at the rear panel, cool the hub. If one fan fails, the remaining two fans cool the hub temporarily, but it is important to replace the module as soon as possible (see chapter 5, Maintenance and Replacement). Figure 3 Rear Panel fan air vents Caution 16 Although the module will continue to run with two fans, a full complement of fans ensures system and data integrity.
Supported Topologies Product Description Devices such as FC-AL disk arrays and HP system servers that support FC-AL can be connected to the hub in a loop that includes one or more servers. All nodes in the loop must be 1063 Mbps short-wave, non-OFC, FC-AL. The ports connected by a cable must have the same optical transceivers. Figure 4, Figure 5, and Figure 6 show typical hub topologies. For details on supported topologies, contact an HP sales representative.
Cascaded Short-Wave Hub Topology The example in Figure 5 shows two model S10 hubs connected in a cascade topology. Cascaded short-wave hubs use one port on each hub for the hub-to-hub connection. Such a configuration increases the potential distance between nodes in the loop an additional 500 meters. The maximum distance between the server and FC-AL devices with cascaded short-wave hubs is 1500 meters (1.5 km). Example Topology: Cascaded Short-Wave Hubs model S10 hub ... ...... ...... ...... ... ... ......
Cascaded Long-Wave Hub Topology Caution Product Description Cascaded FC-AL, non-OFC, model L10 long-wave hubs use the long-wave port for the hubto-hub connection. The maximum supported distance between cascaded long-wave hubs with single-mode 9 micron cable is 3 km. The maximum distance between a server and FCAL devices on cascaded long-wave hubs is, therefore, 4000 meters (500 m + 3000 m + 500 m).
Cascaded hubs must have the same firmware versions to operate properly. If you are using Fibre Channel Manager to manage cascaded hubs, configure the hub that has the LAN (ethernet) connection as a parent hub and the remaining hub as a child hub (see page 60 for more information).
2 INSTALLATION Overview Procedure 1: Prepare to Install the Hub Procedure 2: Unpack the Hub Installation Procedure 3: Verify Hub Operation Procedure 4: Mount the Hub into a Rack (Optional) Procedure 5: Plan the FC-AL Connections Procedure 6: Connect FC-AL Devices Procedure 7: Verify the Connections 21
Overview The procedures for installing an HP SureStore E model S10 or model L10 hub are the following: 1. Prepare to install the hub. 2. Unpack the hub. 3. Verify hub operation. 4. Mount the hub in a rack (optional). 5. Plan the FC-AL connections. 6. Connect the FC-AL devices. 7. Verify the connections. Read this chapter completely before installing the hub or attaching any FC-AL devices to the hub.
Procedure 1: Prepare to Install the Hub Before installing the hub: • Complete site-required arrangements for the hub. • Make sure electrical power and temperature control requirements are met. • Define a strategy for integrating the hub into an existing loop. • Draw a map of all nodes to be connected to the hub.
Procedure 2: Unpack the Hub 1. Unpack and inspect the hub for damage that may have occurred during shipment. 2. Save the boxes and packing materials in case there is damage or anything needs to be reshipped at a future date. 3. Verify that all items shown in Figure 7 are present. Contact an HP sales representative if items are missing. 4. If the hub is to be used as a standalone unit, attach the four rubber feet to the bottom corners of the hub.
Procedure 3: Verify Hub Operation By performing this procedure, you test the hub and verify that it operates properly before you mount it in a rack or connect any devices to it. 1. To initialize the self-test, first plug the power cord into the hub and then into a power receptacle. The hub does not have a power switch. The hub runs the self-test each time the power cord is plugged in or the Reset button is pressed. Note Installation 2.
4. Verify that the 10Base-T port is operating properly. Insert an ethernet cable that is connected to the LAN into the 10Base-T port, and verify that the 10Base-T status LED turns on. (The status LED may begin flashing.) 5. Set the hub IP address and configure the hub as described in chapter 3, RS-232 Interface Functions. 6. Verify the connection between the HP-UX server and the hub.
Procedure 4: Mount the Hub into a Rack (Optional) The hub mounts into any standard HP 19-inch wide EIA cabinet. The hub’s front panel will face the rear of the cabinet. The front of the hub contains the 10 Fibre Channel connectors. You will need a T25 Torx head screwdriver to complete this procedure. Record the serial number, located on the bottom of the hub, and the MAC address, located under the 10Base-T port. The MAC address is unique and cannot be changed. 2.
5. Insert one end of the left rail in the adjoining slot. Line up the hole in the rail lines with the holes in the nut and column (Figure 9). 6. Use a second sheet metal nut and repeat steps 4 and 5 to attach the other end of the rail to the inner column on the front of the rack. Note DO NOT attach screws at this time.
7. Repeat step 4 through step 6 to install the right rail. 8. Position the hub in the rack. Align the hole in each mounting ear bracket with the holes in the assembled rail, nut, and column. 9. Insert a 10–32 x .625 machine screw through the mounting ear bracket, rail, nut, and column on each side of the hub (Figure 10). Tighten the screws. Figure 10 Installing the Hub into the Rack Installation 10. Slide the plenum shroud into the front side of the rack.
11. Secure the brackets to the posts with 10–32 x .625 machine screws (Figure 11).
Figure 12 Hub Correctly Installed in a Rack Installation 12. Plug the PDU cable into the cabinet PDU when you are ready to power on the hub. The hub finishes the self-test in less than 15 seconds. Verify that the hub passes the self-test. If the Fault LED (amber) stays on after self-test, the hub failed. Refer to chapter 4, Troubleshooting, or contact an HP service representative for assistance. If the Power LED is not lighted, refer to chapter 4, Troubleshooting, or contact an HP service representative.
Procedure 5: Plan the FC-AL Connections The hub does not require drivers or specific versions of operating systems. However, systems and FC-AL devices that can connect to the hub do have driver and operating system requirements. Contact an HP sales representative for information on hardware and software requirements for the systems or FC-AL devices you plan to connect to the hub. The HP Fibre Channel Manager User Manual lists operating system requirements for Fibre Channel Manager. 1.
In a cascaded configuration of model S10 short-wave hubs, connect any port on the first hub to any port on the second hub. Figure 13 includes all 18 nodes in the loop formed by FC-AL Device 1, Hub A, Hub B, and FC-AL Device 2: – Port 1 on Hub A connects to FC-AL Device 1. – Port 10 of Hub A connects to Port 1 of Hub B. – Port 10 on Hub B connects to FC-AL Device 2. In this configuration, any unused port on Hub A or Hub B can connect to any compatible FC-AL device.
In a cascaded configuration of FC-AL long-wave hubs, connect the long-wave port on the first hub to the long-wave port on the second hub. Figure 14 shows all 18 nodes in the loop formed by FC-AL Device 1, Hub A, Hub B, and FC-AL Device 2: – Port 1 on Hub A connects to FC-AL Device 1. – The long-wave port of Hub A connects to the long-wave port of Hub B. – Port 1 on Hub B connects to FC-AL Device 2.

Procedure 6: Connect FC-AL Devices After the hub and devices are prepared, connect FC-AL devices as follows: 1. Physically set each FC-AL device to a unique loop ID (hardware address). Refer to the FC-AL device’s manual to set the loop ID. If devices are added during normal operation and duplicate IDs occur, the Fibre Channel driver denies access to both devices until the address conflict is resolved. Change the address of the second (duplicating) device.
If the hub is to be connected to an FC-AL adapter that is connected to another FC-AL device, follow the removal procedures in the document that came with the FC-AL device before disconnecting the device’s cable. If the hub is to be connected to an FC-AL device that is connected directly to a server, follow the removal procedures in the document that came with the FC-AL device before disconnecting the device’s cable.
Procedure 7: Verify the Connections After connecting devices and the server to the hub, verify the connections. Note Because the hub is strictly a pass-through device for FC-AL traffic, there is no hub address and the hub is not listed in ioscan output (HP-UX servers) or the SCSI Adapters window (HP NetServers). For HP-UX servers: 1.

Maintenance and Replacement 5 MAINTENANCE AND REPLACEMENT Introduction Maintenance Replacing the Fan Module 85
Introduction This chapter explains how to maintain the hub and replace the fan module. The fan module is the only replaceable part on the hub. To identify the source of a problem, see chapter 4, Troubleshooting. WARNING 86 Do not attempt to open the hub chassis. Uninsulated parts inside the chassis constitute a hazard.
Maintenance and Replacement Maintenance Good system performance requires clean port optics and cable ferrules to avoid obstructing the optical path. The following preventive maintenance will protect the hub for longer use. • Vacuum to remove dust. • Leave the FC port covers on unused FC ports. • Replace the fan module every three years. • Avoid dropping fiber optic cable ends. This can cause internal glass fractures and intermittent signals.
Replacing the Fan Module The three fans in the fan module operate in parallel. If one fan fails, the other two will continue to operate. However, it is important to replace the fan module immediately. Replace the fan module at least once every three years. You will need the following tools: • Standard Phillips screwdriver • Fan module (A3724-60002) WARNING The power cord is the main disconnect for this product. To protect against hazard, always unplug the AC power cord before removing the fan module.
Maintenance and Replacement Figure 21 Removing the Fan Module 4. Remove the fan module. 5. To insert the new fan module, line up the tabs on the bottom of the fan with the tab openings on the hub (see Figure 22 for positioning). Push the fan module into the hub.
Figure 22 Replacing the Fan Module 6. Fasten the four screws to secure the fan module. 7. Plug the power cord into the hub. The hub powers on and runs the self-test. When the self-test is complete, the Power LED should remain lit and the Fault LED should be off.

Supported Distances Table 11 summarizes the supported distances between a host and devices connected to short-wave ports with 50-micron and 62.5-micron cables and long-wave ports with 9-micron cables. The table does not include combinations of mixed cable lengths. Table 11 Supported Cable Distances Connection Short-Wave1 50 micron (multimode) Short-Wave1 62.
Model L10 Long-Wave Hub Note Stated distances assume 9-micron single-mode cable for the long-wave port and 50-micron multimode cable for the short-wave ports. Reference For ports 1 through 9, the long-wave hub supports distances of 500 meters between the port and a connected FC-AL device. For the long-wave port, the long-wave hub supports distances up to 3 kilometers between two long-wave hubs. Under certain conditions, cascaded long-wave hubs are supported at distances up to 10 kilometers.
If both ends of the Fibre Channel cable are between the limits listed in step 5, the two long-wave hub’s are verified for cascading up to 10 km using this cable plant. If the meter readings are not within range, verify that the Fibre Channel cable is securely connected to the hub’s long-wave port. Also verify, that the cable connectors are clean by wiping them with a lint-free cloth dampened with reagent grade isopropyl alcohol and blowing the connectors dry with clean, compressed air.

Fibre Channel Logically, Fibre Channel is a bidirectional, full-duplex, point-to-point, serial data channel structured for high performance capability. Physically, the Fibre Channel is an interconnection of multiple communication ports, called NL_Ports, interconnected by a switching network, called a fabric, a point-to-point link or an arbitrated loop.
N_Port A “Node” port. A Fiber Channel-defined hardware entity that performs data communication over the FC-AL link. It is identifiable by a unique World Wide Name. It can act as an originator or a responder. N_Port Identifier A unique address identifier by which an N_Port is uniquely known. It consists of a Domain (most significant byte), an Area, and a Port, each 1-byte long. The N_Port identifier is used in the Source Identifier (S_ID) and Destination Identifier (D_ID) fields of an FC-AL frame.
