1.3 Ultra 2 Host System—Power Connection Requirement You can connect a controller module to an Ultra 2 host system; however, you must connect the power cord of the Ultra 2 host to one of the AC power sequencers in the expansion cabinet that contains the controller module. You need to order one of the following power cords depending on the type of power sequencer in the expansion cabinet (FIGURE 1-5): ■ Ultra™ Enterprise™ expansion cabinet and StorEdge expansion cabinet— part number 530-2197-xx ■

1. Gain access to the AC power sequencers. See the documentation that came with the expansion cabinet. 2. Route the power cable from the Ultra 2 host under the expansion cabinet frame on the same side as the power sequencer. 3. Plug the power cord from the Ultra 2 host into the top power connector of either power sequencer (FIGURE 1-5). The power connectors are located on the other side of the power sequencer from the main switch. 4. Reassemble the expansion cabinet. See the documentation that c
