1.5 Device Cooling Proper device operation requires cooling. The two fans in the pedestal and in the power supply. • The fan mounted on the rear of the pedestal cools the storage devices. • The power supply internal fan cools the 5.25-inch devices and the power supply. As shown in Figure 1–4, both fans draw air through the front of the pedestal, through the storage devices, and exhaust it out the rear. -

Page 15: Installing A Pedestal
Installing and Operating a Pedestal This chapter describes the procedures for installing and operating a BA346–KB series deskside expansion pedestal. Subjects addressed include selecting the installation area, unpacking the pedestal, installing storage devices, connecting cables, and checking pedestal operation 2.1 Installing a Pedestal You can usually install the pedestal within 2 meters (6.6 feet) of the SCSI controller and next to an ac receptacle. -
Page 16: Selecting The Installation Area
2.2 Selecting the Installation Area The location of the pedestal depends upon the availability of ac power and the distance to the SCSI controller. SCSI bus length is critical to selecting the installation area. Therefore, before selecting the installation area, read Section 3.3. CAUTION Blocking or restricting the input or output air flow can cause overheating. -

2.4 Packing a Pedestal WARNING To prevent personal injury always use two people to pack, unpack, or move the pedestal in the shipping container. Complete the following procedures to pack a pedestal for shipping: CAUTION To prevent damage to the pedestal, you must use the approved packing materials and pack the pedestal as described in this procedure 1. -

2.9 Installing SBBs After installing the options and configuring the pedestal, you can install the SBBs. Be sure that you have set the storage device addresses before installing the devices in the pedestal. The combinations of the SBB guides, shelf slots, and backplane connectors preclude installing an SBB incorrectly;... -
Page 22: Connecting The Scsi Bus Cables
2.10 Connecting the SCSI Bus Cables Once you have installed all the storage devices, you can connect the SCSI bus cable. CAUTION Connecting the SCSI bus cable with power applied to either the controller or the pedestal can generate erroneous signals and cause the SCSI bus to “hang.” Always turn off the power on both the host and the pedestal when connecting or disconnecting the SCSI cables. -

Page 24: Operating The Pedestal
2.12 Operating the Pedestal Use the pedestal power switch, a “push-to-make, push-to-break” type, to turn on the pedestal. The pedestal power switch is shown in Figure 2–11. When the ac power is on the green pedestal power LED is on (see Figure 2–11). When the SCSI bus is active the LEDs on the 5.25-inch devices and the SBBs indicate the status of the storage devices. -
Page 25: Mounting The Door
2.13 Mounting the Door Once the pedestal is operating you can install the door to provide security for the storage devices. (A locked door precludes removing storage devices.) Figure 2–13 shows how to mount the door by inserting the hinge pins on the door into the holes in the bezel. Figure 2–13 Mounting the Door HINGE CXO-4554A-MC... -
Page 26: Replacing A Storage Sbb
2.14 Replacing a Storage SBB There are three methods for replacing a storage SBB with an identical SBB: • Hot swap —This method requires that the SCSI controller support removing and installing SBBs while the bus is active, Check the controller documentation to determine if hot swap is supported. -
Page 27: The Standard Configuration
Configuring the Pedestal This chapter describes the standard BA346–KB pedestal configuration and how to change it. 3.1 The Standard Configuration You can install the dual bus and the 5.25-inch device option at any time. Installing either option requires changing the pedestal configuration. Digital recommends that you install the options during the initial installation. -
Page 28: Scsi Bus Cables And Accessories
3.2 SCSI Bus Cables and Accessories After installing the options, there are two parts to configuring a pedestal—connecting the internal cables and setting the configuration address. Most cabling configurations and all SCSI address configurations are compatible. However, be sure to check Table 3–5 (page 3–7) for a description of each configuration. -
Page 29: Scsi Buses
3.3 SCSI Buses The reliability of data transfers on a SCSI bus is a function of the following: • The bus transmission rate • The bus type (8-bit or 16-bit) • The maximum SCSI bus length (a function of the bus type, the transmission rate, and the use of SCSI bus converters) •... -
Page 30: Internal Scsi Buses
3.4 Internal SCSI Buses Figure 3–3 shows the three internal SCSI bus configurations. Digital recommends that the internal SCSI bus length be kept as short as possible. The total internal SCSI bus cable length is distance from the controller terminator to the pedestal terminator. -
Page 31: Removing The Side Panel
3.5 Removing the Side Panel Whenever you configure the pedestal, you must complete the following procedures: 1. Turn off the power to both the controller and the pedestal. 2. Disconnect the pedestal power cord. 3. Disconnect the external SCSI bus cables. 4. -
Page 32: Setting The Configuration Address
3.6 Setting the Configuration Address There are both configuration addresses and device addresses. Jumpers W1-W3 determine the eight configuration addresses that can be used for both 8-bit (addresses 0-6) and 16-bit (addresses 0-6 and 8-14) devices. Note SCSI device address 7 is the SCSI controller address. Use jumpers W1-W3 to set the address configurations. -
