2. Create a redundant host connection by connecting a second SAS cable from a
second SAS HBA (or a second SAS port in the HBA) to a host port on
controller B in the DCS3860 storage system.
The DCS3860 can support up to two redundant host connections to a base
DCS3860 storage system. With the optional host interface card installed in each
controller, up to four redundant host connections are supported.
Cabling the power supply
The DCS3860 requires 200-240V AC power. Ensure that it is connected only to the
correct AC supply voltage. If there are multiple DCS3860 units to be connected,
ensure that the AC source and the rack Power Distribution Unit current ratings are
sufficient to support the DCS3860 operating and surge current requirements.
Complete the following steps to connect the power supply cable.
1. Using the strap that is provided with the power supply, tie the power supply
cord to the strap to provide strain relief and to prevent the power cord from
accidently being unplugged.
2. Connect the power cable to the power supply.
3. Continue with “Powering on the DCS3860” on page 56 for the initial startup of
the storage expansion enclosure.
Relocating the DCS3860
Before you move a DCS3860 with populated hard drive drawers, you must obtain
a rack relocation kit. Follow the instructions provided with the relocation kit to
avoid potential damage to the DCS3860:
v
You can unmount the system from the rack and move the system alone. Use the
DS/DCS dense drive enclosure relocation kit.
v
You can also move the rack with the system mounted in it. Use the rack
relocation kit.
