Table 1–1 SW300 Specifications Characteristic Specification Dimensions (nominal) 838.20 mm (33.00 in) height 476.25 mm (18.75 in) width 482.60 mm (19.00 in) depth Weight Cabinet with shipping packaging 106.65 kg (242.00 lb) Maximum configuration 77.85 kb (178.
1.3 Major Components The major components of the SW300 enclosure are shown in Figure 1–2. Figure 1–2 SW300 Components (Cabinet Removed for Clarity) POWER A POWER B POWER SUPPLY SBB DUAL-SPEED BLOWER STORAGE DEVICE SBB AC POWER ENTRY CONTROLLER A ENVIRONMENTAL MONITOR UNIT HS ARRAY CONTROLLER AC POWER ENTRY CONTROLLER B CXO-4305A-MC 1.3.
remains powered by the ac power entry controller B. As shown in Figure 1–3, this configuration provides complete power redundancy to the shelf ’s devices. The ac power entry controller A provides power to the four power supply SBBs on power supply bus A. This is the minimum power configuration (4+0) for the system. The power supply SBB located at the top of power supply bus B provides power for 4+1 redundancy.
1.3.3 Environmental Monitor Unit (EMU) The EMU provides increased protection against catastrophic subsystem faults. The SW300 enclosure has two EMUs to provide complete system redundancy. If one EMU should fail, the other continues to monitor all system functions. The EMU works with the controller to warn the user of various types of existing or impending subsystem failures.
– Turns off the SHELF_OK signal – Activates the audible alarm – Resets the host controller(s) If one power supply SBB fails, but four or more power supply SBBs are still functioning, the EMU generates a fault condition and performs the following actions: • – Turns on the Shelf Fault (amber) LED on the front of the EMU – Turns on the Fault (amber) LED located on the upper right corner on the front of the SW300 Senses cabinet temperature—The EMU senses two different temperatures: warning and reset
1.3.4 HS Array Controllers The card cage assembly contains two slots for controller and cache memory modules. These slots provide the mechanical mounting, power, and signal interfaces for the units they house. This assembly allows for the mounting of two controllers to provide redundancy. Note This manual covers minimal controller functionality.
1.3.5 Dual Speed Blowers As shown in Figure 1–4, the SW300 enclosure has eight rear-mounted blowers that pull air from the front of the cabinet to the rear. Connectors on the backplane provide the +12 V dc of power to operate the blowers. Logic signals allow the status of the shelf blowers to be monitored by the EMU.
1.3.6 Power Supply SBBs Note The BA35X–HA power supply is not supported in the SW300 enclosure. The power supply SBB (BA35X–HD), shown in Figure 1–5, converts ac input from the ac power entry controller to +5 V dc and +12 V dc for use by the SW300 components. The SW300 enclosure provides connections for up to eight power supply SBBs. A minimum of four operable power supply SBBs is required for system operation. The SW300 enclosure is designed for 4+1 redundant power supply.
1.3.7 Storage Device SBBs The storage devices come in either a 3½-inch or a 5¼-inch SBB, as shown in Figures 1–6 and 1–7 respectively. The SW300 enclosure provides space for 24 3½-inch SBBs, 8 5¼-inch SBBs, or combinations of each. A 3½-inch SBB occupies one slot in a shelf. A 5¼-inch SBB requires three slots in a shelf. The disk drive SCSI bus address for 5¼-inch SBBs is usually assigned based upon the shelf backplane connector but also can be assigned manually in some SBBs.

4.4 HS Array Controller LEDs and Fault Notification The operator control panel (OCP), normal operation, and fault notification are discussed using a typical HSZ40 controller for reference. 4.4.1 HSZ40 Operator Control Panel The HS controller OCP contains the following: • One reset button (//) with an embedded green LED • One button per SCSI port • Six amber LEDs1 Figure 4–3 shows the HSZ40 controller OCP.
Under normal operation, the amber LEDs indicate the state of the respective SCSI–2 buses. When the devices on the buses are functioning correctly, the amber LEDs will not be lit or flashing. Pressing one of the port buttons at this time will light its corresponding amber LED and quiesce its SCSI–2 port. A port must be quiesced to remove or warm swap a device on the SCSI–2 bus for that port.

5 Removal and Installation Procedures This chapter describes the procedures to remove and install the following field replaceable units (FRUs) in the SW300-series redundant array of independent disks (RAID) enclosure: • StorageWorks building block (SBB) power supply or storage device • Environmental monitor unit (EMU) • Controller • Dual speed blower • AC power entry controller 5.
4. Use both hands and pull the power supply SBB out of the shelf. Figure 5–1 Removing a Power Supply SBB (Cabinet Removed for Clarity) CXO-4314A-MC 5.2 Installing a Power Supply SBB Use the following procedure to install a power supply SBB: 1. Insert the replacement power supply SBB into the guide slots and push it in until it is fully seated and the mounting tabs engage the shelf. 2. Connect the power cord to the power supply SBB. 3.
5.4 Removing a Storage Device SBB CAUTION Warm swap supports removing and replacing only one SBB at a time. Should another SBB need to be swapped, the entire warm swap procedure must be repeated. The steps in this section must be followed in their exact order to be sure of the following: • Preserve data integrity (especially for devices with older SCSI interface designs). • Reduce chances of making a port unusable for a long period, which can render several devices inaccessible.
2. Quiesce the SBB’s port by pressing and holding the controller port button for the SBB. Continue holding the button until all controller amber OCP LEDs light. Note Only one port can be quiesced at any time. If the button is not held long enough, or multiple buttons are pushed in quick succession, all buttons are ignored (no ports are quiesced). The button must be pressed and held again to quiesce the port. 3.
When the SBB is removed, the LED pattern on the controller OCP changes to solid amber, and normal operation on the ports resume. At this time, the removed SBB’s port LED on the controller OCP turns on. The LED stays on until the SBB is returned to its slot or until another SBB is inserted in the slot. The remaining port LEDs on the controller OCP turn off. 5.
For additional information on storage device replacement, see the StorageWorks Solutions Shelf and SBB User’s Guide. 5.6 Removing an Environmental Monitor Unit Use the following procedure to remove an EMU: Note This component can be removed and installed while power is on. If the system contains a redundant EMU, then one EMU can be hot swapped without affecting system operation. 1. Loosen the two captive retaining screws with a flat-blade screwdriver. 2.
5.9 Installing a Controller Use the following procedure to install a controller: Note This component can be removed and installed while power is on. 1. Slide the controller into the slot using its slot’s rightmost rails as guides. 2. Use a gentle up-and-down rocking motion to help seat the controller into the backplane. 3. Press firmly on the controller until it is seated. 4.
