5. Before removing the DS3950 from the shipping box, remove the components
from the DS3950 chassis to lighten the unit. See “Removing the CRUs” on
page 36.
6.
Record the serial number, machine type and model number, and RAID
controller MAC addresses for your DS3950 storage subsystem in Appendix A,
“Records,” on page 167.
The serial number, machine type, and model number are located on the left
edge of the front unit as shown in Figure 11.
The MAC addresses are located near the Ethernet ports on each RAID
controller.
7. Install and secure the DS3950 chassis in the rack cabinet. See “Installing the
DS3950 into a rack on the support rails” on page 40.
8. If needed, replace the components in the installed DS3950 chassis. See
“Replacing the components” on page 42.
9. Install the storage expansion enclosure or enclosures you will cable to the
DS3950 in the rack cabinet. Follow the instructions in the Installation, User’s,
and Maintenance Guide for your storage expansion enclosure to set up and
mount the storage expansion enclosures.
10.
Use SFP modules and Fibre Channel cables to cable the DS3950 to the EXP395
or EXP810 storage expansion enclosure. See “Connecting storage expansion
enclosures to the DS3950” on page 55.
11. Perform one of the following cabling tasks to enable management of the
DS3950 configuration:
v
If you are using out-of-band management, cable the DS3950 Ethernet ports
to either the management workstation or the host.
v If you are using in-band management, cable the DS3950 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 DS3950 using Fibre Channel host ports” on page 82.
12. Connect the power cables for the DS3950. See “Cabling the ac power supply”
on page 92.
Attention:
Before you turn on the power to the DS3950 storage subsystem, it must be
populated with at least two E-DDMs.
If at least two E-DDMs are not installed in the DS3950, an insufficient load to
the enclosure power supplies might cause them to intermittently appear as
failed, falsely indicating the power supplies are bad. All of the E-DDMs in the
DS3950 storage subsystem and the connected storage expansion enclosure or
enclosures must contain no prior configuration data.
