| *1 | : | Mid Plane. A board that is located between the front and rear (SVC or FRT, CM or IOM side) of the ETERNUS DX. |
| *2 | : | All of the host interfaces on the CM that will have maintenance performed go offline. When a multipath configuration is used, switch to the host paths of the CM that will not have maintenance performed to continue operation. |
| *3 | : | When hot expanded, each CM must be pulled out to expand. Therefore, all host interfaces on the CM to be expanded will temporarily go offline. |
| *4 | : | Bootup and Utility Device. |
| *5 | : | An I/O suspension may be required depending on the firmware changes. |
| *6 | : | Can be replaced for configurations with two or more CEs. All of the paths on the CE that will have maintenance performed go offline. When a multipath configuration is used, switch to the host paths of the CE that will not have maintenance performed to continue operation. |
| *7 | : | Operation can be continued during a failure. The status of the DE can be monitored via ETERNUS Web GUI or ETERNUS CLI. |
