System Overview : Dell PowerVault 220S and 221S Systems Service Manual Split-Bus Module Your storage system supports three SCSI bus modes controlled by the split-bus module: Joined-bus mode Split-bus mode Cluster mode These modes are controlled by the position of the bus configuration switch when the system is turned on. Figure 6 illustrates the switch position for each mode. For more information on configuring the SCSI bus modes, see your Installation and Troubleshooting Guide. Figure 6.
System Overview : Dell PowerVault 220S and 221S Systems Service Manual See Table 5 for a description of split-bus module modes and functions. NOTE: To change the SCSI bus mode, you must change the position of the bus configuration switch before turning on the storage system. Changing the position of the bus configuration switch while the system is on will not affect system operation.

Basic Troubleshooting : Dell PowerVault 220S and 221S Systems Service Manual Ensure that the cable connectors are firmly seated before you tighten the captive thumbscrews. When detaching the cable, avoid damage to the cable by grasping and pulling on the cable connector rather than the cable. Also, separate the connectors carefully to avoid damage to the connector pins. Indicators Overview The LED indicators on your storage system provide valuable information when troubleshooting the system.
Basic Troubleshooting : Dell PowerVault 220S and 221S Systems Service Manual For a list of all SCSI hard-drive LED flash patterns, including the ones described previously, see Table 3. To troubleshoot your SCSI hard drives, complete the following steps: 1. Is the storage system turned off? Yes. Turn on the storage system using the on/off switch on the back of the power supply (see Figure 8 for switch location). No. Go to step 2. 2.
Basic Troubleshooting : Dell PowerVault 220S and 221S Systems Service Manual Drive(s) not seen during the host boot If any of these events occur, perform the following diagnostic steps: 1. Is the green AC status LED indicator on the power supply(s) illuminated? (See Figure 8 for location.) No. See "Troubleshooting a Power Supply." Yes. Go to step 2. 2. Are the following system components updated with the latest firmware and device drivers? Enclosure EMM Hard-disk drives Host bus adapter or PERC No.
Basic Troubleshooting : Dell PowerVault 220S and 221S Systems Service Manual down to prevent damage. Troubleshooting a Power Supply The three power-supply LEDs on the back of the power supply (see Figure 8) indicate the status of the power supply when it is connected to the backplane (see Table 7 for a description of each indicator and its function). If all three power-supply indicators are off or if the power-supply fault LED indicator is illuminated, perform the following steps: 1.
Basic Troubleshooting : Dell PowerVault 220S and 221S Systems Service Manual No. Go to step 3. Yes. A power supply has failed. Replace the failed power supply (see "Replacing the Power Supply"). 3. Is the amber fault LEDs for blower A and/or blower B illuminated? (See Figure 8 for LED locations.) No. Go to step 4. Yes. One of the blowers has failed. Replace the failed cooling module (see "Replacing a Cooling Module").
Basic Troubleshooting : Dell PowerVault 220S and 221S Systems Service Manual NOTE: Verify that your SCSI cables meet the following minimum specifications: For U160 systems -- SPI3 specification For U320 systems -- SPI4 specification SPI4 cables are backward-compatible and will work on U160 subsystems. However, using a SPI3/U160 cable from another external device on a U320 enclosure may cause unpredictable and erratic behavior that could result in data loss. Inspect your SCSI cables for damage.
