5. Before removing the DS4700 Express from the shipping box, remove the
components from the DS4700 Express chassis to lighten the unit. See
“Removing the CRUs” on page 40.
6. Record the serial number, machine type and model number, and RAID
controller MAC addresses for your DS4700 Express Storage Subsystem in
Appendix A, “Records,” on page 191.
The serial number, machine type, and model number are located on the left
edge of the front unit as shown in Figure 17.
The MAC addresses are located near the Ethernet ports on each RAID
controller.
7. Install and secure the DS4700 Express chassis in the rack cabinet. See
“Installing the DS4700 Express into a rack on the support rails” on page 46.
8. If needed, replace the components in the installed DS4700 Express chassis.
See “Replacing the components” on page 48.
9. Install in the rack cabinet the DS4000 storage expansion enclosure or
enclosures you will cable to the DS4700 Express. Follow the instructions in the
Installation, User’s, and Maintenance Guide for your DS4000 storage
expansion enclosure to set up and mount the storage expansion enclosures.
Attention
Before powering on the DS4700 Express Storage Subsystem, it must be
populated with at least two E-DDMs. If at least two E-DDMs are not
installed in each attached storage expansion enclosure or DS4700
Express Storage Subsystem, when you power on the DS4700 Express
and its attached storage expansion enclosures, your standard storage
partition key might be lost and must be regenerated using instructions on
the IBM DS4000 Solutions and Premium Features Web site:
https://www-912.ibm.com/PremiumFeatures/
In addition, the resulting insufficient load to the enclosure power supplies
might cause them to intermittently appear as failed, falsely indicating the
power supplies are bad. All E-DDMs in the DS4700 Express Storage
Subsystem and the connected storage expansion enclosure or
enclosures must contain no prior configuration data.
10. Use SFP modules and fibre channel cables to cable the DS4700 Express to
the DS4000 storage expansion enclosure or enclosures. See “Connecting
storage expansion enclosures to the DS4700 Express” on page 68.
11. Set the enclosure IDs for all storage expansion enclosures in the configuration.
See “Storage expansion enclosure settings” on page 97.
