Install the HP Model 30/FC High Availability Disk Array 1. Check Power Requirements Refer to the disk array DC power requirements in the Reference chapter of the Hewlett-Packard Model 30/FC High Availability Disk Array Service Manual (part number A3661-90002) to make sure the installation site meets these requirements. The HP Model 30/FC High Availability Disk Array uses 200VAC to 240VAC nominal; 110VAC is not supported.
The HP Model 30/FC High Availability Disk Array is rated to draw approximately 5amps at 230VAC steady state current for normal operation. However, when powered on, the disk array draws a heavy in-rush (surge) current (up to 115 amps for 10 to 12 ms) that could trip standard industrial circuit breakers.
i. Remove the disk array’s front bezel by grasping its sides and pulling straight out. If the bezel is difficult to remove, use a small standard screwdriver to carefully loosen the bezel at its four outside corners. To remove front bezel, grasp the sides of the panel and pull straight out. To install front bezel, press panel onto ballstuds. Ballstud Figure 10. Removing the front bezel 3. Prepare the Cabinet The HP Model 30/FC High Availability Disk Array requires 11 EIA units of space in the cabinet.

4 – Cluster Cabling and Setup 1. Plan the HP FC-AL Hub Connections The HP NetServers should be powered down when making the FC-AL connections to the FC I/O adapters. Power down the HP NetServers if they are not already powered down. The HP Model 30/FC High Availability Disk Array and the cabinet should still be powered down at this time. CAUTION Incorrect wiring can lead to problems, such as devices left off the loop and inaccessible by the HP NetServer. Follow the guidelines below before starting. a.
NOTE To protect hub ports, port covers should remain installed in all unused ports. 3. Connect Cascading HP FC-AL Hubs If using cascading hubs, connect the two HP FC-AL hubs to each other. • If connecting short-wave hubs, refer to figure 28. • If connecting long-wave hubs, refer to figure 29. – When installing long-wave cascading hubs (HP A4839A), make sure the long-wave port (Port 10) is connected only to the long-wave port (Port 10) on the other long-wave hub. 4.
5. Connect the HP Model 30/FC High Availability Disk Array to the HP FC-AL Hub The external Fibre Channel connectors link the disk array to an HP FC-AL hub through fiber optic cables. These connectors are located at the back of the disk array, on the Fibre Channel Interconnect (printed circuit assembly). The Fibre Channel connectors are located above the SPs. One Fibre Channel connector is associated with each SP.

6. Verify FC-AL Cabling Correct cabling example, HP FC-AL short-wave hub (HP A3724A) In a cascaded configuration of HP FC-AL short-wave hubs, use a short-wave cable to connect any port on the first HP FC-AL hub to any port on the second HP FC-AL hub. In the following example, Port 1 on Hub A connects to FC-AL Device 1; Port 10 of Hub A connects to Port 1 of Hub B; and Port 10 on Hub B connects to FC-AL Device 2. Any shortwave FC-AL device or hub can connect to Port 10 of a short-wave hub.
Incorrect cabling examples Do NOT cable together two ports on the same HP FC-AL hub. Ports between the two connections will be eliminated from the FC-AL loop. Figure 30. Incorrect cabling example: connected ports on the same HP FC-AL hub Do NOT leave cables that are connected to the HP FC-AL hub disconnected at the opposite end of the cable. Figure 31. Incorrect cabling example: disconnected cable Do NOT attach more than one cable between any two HP FC-AL hubs. Figure 32.
Nonsupported cabling example Connecting an HP FC-AL hub to more than one other HP FC-AL hub is NOT a supported configuration. Figure 34. Non-supported cabling example: more than two HP FC-AL hubs connected Do not attach power cords or power up the disk array or the cabinet at this time.
