It also provides configuration rules and ac power distribution information. 1.1 Product Description A vertical mounting kit is a floor-mounted stand that encloses a DECstor/me modular storage shelf. A typical BA35X-VA vertical mounting kit is shown in Figure 1-1. Figure 1-1 Typical BA35X-VA Vertical Mounting Kit ------------------------------------------------------------ CXO-3639A-PHðTX Introducing the Vertical Mounting Kit 1.1 Product Description The part number for both versions of the vertical mounting kit is the same: BA35X-VA. Whether you purchase a single or double version depends on how many vertical mounting kits you order. For each single-height shelf, order one BA35X-VA vertical mounting kit; for each double-height (BA350-EA) shelf, order two BA35X-VA vertical mounting kits. For example, if your configuration uses one BA350-EA (double-height) shelf and two BA350-SA (single-height) shelves, you would order four BA35X-VA vertical mounting kits: · Two vertical mounting kits for the BA350-EA shelf · One vertical mounting kit for each BA350-SA shelf No tools are required to assemble or disassemble a vertical mounting kit--the parts ``snap'' together. Vertical mounting kits are shipped fully assembled with the ac distribution unit and the modular storage shelf installed. The modular storage shelf has system building blocks (SBBs) installed and small computer system interface (SCSI) buses configured according to the customer 's order. Shelf power supplies are connected to the ac distribution unit. The physical specifications of the vertical mounting kits are described in Table 1-1. Table 1-1 Physical Specifications of the Vertical Mounting Kits ------------------------------------------------------------ Specification Single Vertical Mounting Kit Double Vertical Mounting Kit ------------------------------------------------------------ Height 578 mm (22.75 in) 578 mm (22.75 in) Width 203 mm (10 in) 356 mm (14 in) Depth 400 mm (15.75 in) 400 mm (15.75 in) Weight 17 kg (37 lb) 29 kg (63 lb) ------------------------------------------------------------ 1.2 Configuration Rules The following configuration rules apply to vertical mounting kits: · Measure capacities by the number of shelves that can be installed: - One BA350-SA shelf can be installed in a single vertical mounting kit. - One BA350-EA shelf can be installed in a double vertical mounting kit. · Connect no more than two vertical mounting kits in series to the same wall receptacle. (Each vertical mounting kit has an unswitched ac outlet for this purpose. See Section 1.3 for additional information.) · Mount all shelves with the power supply at the bottom (slot 7), as shown in Figure 1-2. · Reserve slot 6 for either a redundant power supply or a battery backup unit (BBU). 1-2 Introducing the Vertical Mounting Kit Introducing the Vertical Mounting Kit 1.2 Configuration Rules Figure 1-2 Shelf Orientation in a Single Vertical Mounting Kit To maintain the stability of a single vertical mounting kit, install SBBs in the order specified in Section 2.2. 1.3 AC Power Distribution Each vertical mounting kit has an ac distribution unit that provides switch- controlled ac power to the shelf power supply. (The only exception to this is the double vertical mounting kit used with the SZ200 RAID subsystem, which has only one ac distribution unit.) The ac distribution unit in your vertical mounting kit will be one of two types, depending on when you purchased your kit: · The initial version of the ac distribution unit used with the vertical mounting kits had an unswitched, built-in, 10.2-centimeter (4-inch) power cord for connection to the ac distribution unit in a second vertical mounting kit. The short length of this built-in cord did not allow for much flexibility in configuration arrangements. · The second-generation ac distribution units have replaced the unswitched power cord with a switched ac outlet. This ac outlet can be used for connecting either another vertical mounting kit's ac distribution unit or an optional redundant power supply in a BA350-EA shelf. In either case, you must order an ac power cord for this additional connection. Introducing the Vertical Mounting Kit 1-3 Introducing the Vertical Mounting Kit 1.3 AC Power Distribution Table 1-2 lists the power cords available for ac distribution units. These power cords must be ordered separately because they are country specific. In general, the power cords listed in Table 1-2 have the following characteristics: · Are rated at 10 amps at the specified operating voltage · Are 2.5 meters (8.2 feet) long · Have a country-specific plug · Have an IEC 320 C-14 compatible connector The only exception is the BN27S-03 power cord used in Japan and the United States; it is rated at 15 amps and is 3 meters (9.8 feet) long.
