2.Start the DS4000 Storage Manager client software. The Enterprise Management window opens.
3.Add the DS4000 subsystem to the DS4000 Enterprise Management domain using the default IP addresses.
4.In the Enterprise Management window, click on the name of the default storage subsystem. The Subsystem Management window opens.
5.In the Subsystem Management window,
6.In the Change Network Configuration window, click on the Controller A and Controller B tabs and type the new TCP/IP addresses in their appropriate fields. Click OK.
7.Close the Subsystem Management window, wait at least five minutes, then delete the default DS4000 storage subsystem entry in the Enterprise Management window. The default DS4000 storage subsystem entry still displays, but shows an “unresponsive” icon.
8.If applicable, change the IP address of the Ethernet port in the management station to a value that is on the same TCP/IP subnet as the controller Ethernet port IP addresses that you just assigned. Exit DS4000 Storage Manager, then restart.
9.Add a new storage subsystem entry in the Enterprise Management window, using the new assigned IP addresses.
Note: To manage storage subsystems through a firewall, configure the firewall to open port 2463 to TCP data.
AC power supply and fan units
The DS4700 Express Storage Subsystem (models 70A, 70H, 72A, and 72H) has two removable ac power supply and fan units. Each power supply and fan unit contains one power supply and two fans. The four fans pull air through the drive from front to back across the drives.
The fans provide redundant cooling, which means that if one of the fans in either fan housing fails, the remaining fans continue to provide sufficient cooling to operate the storage subsystem. The power supplies provide power to the internal components by converting incoming ac voltage to dc voltage. If one power supply is turned off or malfunctions, the other power supply maintains electrical power to the storage subsystem. To preserve the optimal airflow, do not remove a failed power supply and fan unit CRU from the DS4700 Express chassis until you are ready to replace it with a new CRU.
Figure 4 on page 13 shows power supply and fan unit components for the DS4700 Express model 70 and Figure 5 on page 13 shows power supply and fan unit components for DS4700 Express model 72.
Note: Although both power supply and fan units (left and right) are identical, they are seated in the DS4700 Express chassis in opposite orientations. If the power supply and fan unit cannot fully be inserted in the power supply and fan unit bay, flip it 180 degree and reinsert it.
