Introduction: Dell PowerVault 220S and 221S Systems User's Guide Split-Bus Module Your system supports three SCSI bus modes controlled by the split-bus module: Cluster mode Split-bus mode Joined-bus mode These modes are controlled by the position of the bus configuration switch when the system is turned on. Figure 1-6 illustrates the switch position for each mode. Figure 1-6. Bus Configuration Switch Modes file:///C|/Users/rishi_sood/Desktop/220s/en/ug/8f182c11.
Introduction: Dell PowerVault 220S and 221S Systems User's Guide The only difference between cluster mode and joined-bus mode is the SCSI ID occupied by the enclosure services processor. When cluster mode is detected, the processor SCSI ID changes from 6 to 15, allowing a second initiator to occupy SCSI ID 6. As a result, hard-drive slot 13 (normally occupying SCSI ID 15) is disabled, leaving 13 available hard-drive slots in cluster mode.
Introduction: Dell PowerVault 220S and 221S Systems User's Guide Management functions — Includes SES and SAFTE reporting to the host initiator, control of all enclosure LED indicators, and monitoring of all enclosure environmental elements such as temperature sensors, cooling modules, and power supplies. A system with redundant enclosure management features two EMMs that are designated as primary and secondary and that can be configured in either a cluster, joined-bus, or split-bus mode.
Introduction: Dell PowerVault 220S and 221S Systems User's Guide Power Supply/Cooling Modules Your system supports two combined power supply and cooling modules. While the system is designed to operate normally with only one functional power supply, both cooling modules (with two blowers each) must be present for proper cooling. If only one power supply is needed, a blank must be inserted into the other slot to mount the second cooling module.
Introduction: Dell PowerVault 220S and 221S Systems User's Guide Preventing Unauthorized Access to the System The PowerVault 220S can be secured with the lock on the rack door. The PowerVault 221S has a keylock mechanism on the top of the front bezel that prevents unauthorized access to the system. Power Protection Devices A number of devices are available to protect against power problems such as power surges, transients, and power failures. The following subsections describe some of these devices.
