6. Record the serial number, machine type and model number, and RAID
controller MAC addresses for your DS4800 Storage Subsystem in Appendix B,
"Records," on page 179.
The serial number, machine type, and model number are located on top of
each the DS4800 subsystem unit. The MAC addresses are located near the
Ethernet ports on each RAID controller, as shown in Figure 100 on page 179.
You may not be able to easily access this information after you install the
DS4800.
7. Install and secure the DS4800 chassis in the rack cabinet. See "Installing the
DS4800 on the support rails" on page 41.
8. Replace the components in the installed DS4800 chassis. See "Replacing the
components" on page 43.
9. Install in the rack cabinet the DS4000 storage expansion enclosure or
enclosures you will cable to the DS4800. 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 you power on the DS4800 Storage Subsystem, the DS4800 must
be cabled to at least one storage expansion enclosure populated with at
least two drives. If at least two drives are not installed in each attached
storage expansion enclosure when you power on the DS4800, your
standard storage partition key will be lost and will need to be regenerated

All drives in the connected storage expansion enclosure or enclosures
must contain no prior configuration data. Additionally, if at least two drives
are not installed in each attached storage expansion enclosure, the
resulting insufficient load to the storage expansion enclosure power
supply CRUs might cause the drive expansion enclosure power supply
CRUs to intermittently appear as failed and then reappear in an optimal
state, falsely indicating that the power supply CRUs are bad.

enclosures in the configuration to unique values. The EXP810 drive expansion
enclosures automatically adjust the enclosure IDs to ensure unique enclosure
IDs among themselves. See "Storage expansion enclosure settings" on page

DS4800 configuration:
v If you are using out-of-band management, cable the DS4800 Ethernet ports
to either the management workstation or the host. See "Connecting
secondary interface cables" on page 81.
v If you are using in-band management, cable the DS4800 host channels to
the fibre channel host bus adapters (HBAs) in either the hosts or the fibre
channel switch that connects to the host HBAs. See "Connecting hosts to
the DS4800" on page 79.
