Turning on the storage subsystem
Power-on overview
Review the following information before you continue with the power-on
procedure below.
Check the system documentation for the hardware devices that you intend to
power up, and then determine the proper startup sequence. Use the following
power-on sequence, where applicable:
1. Turn on the power to the supporting devices (for example, Ethernet
switches and management stations) before the storage subsystem.
Attention: If you will use out-of-band (direct) configuration management
(using the Ethernet), you must set up the Dynamic Host Configuration
Protocol (DHCP) or BOOTP server before you turn on the power. Setting
up the server allows the controllers to obtain the corresponding IP address
when you turn on the power to the storage subsystem. To configure the
server, you need the controller’s Media Access Control (MAC) address.
The MAC addresses appear on labels near the Ethernet ports on each
controller.

For more information, see the software installation guide for
your operating system.
2. Important: You must turn on the storage expansion enclosures and verify
that the storage expansion enclosure fibre channel connections are optimal
by checking the indicator LEDs before you turn on the DS5100 and
DS5300. The controllers might not recognize the correct configuration if
the storage expansion enclosure hard disk drives are powered up after the
DS5100 and DS5300. For instructions on how to power up the storage
expansion enclosures, refer to the storage expansion enclosure
documentation.
3. Turn on the power to the storage subsystem; then restart or turn on the
power to the host.
Note: Depending on your operating system, you might not have to restart
the host. For more information, see the software installation guide
for your operating system.
Use this procedure to turn on power to a storage configuration at the initial startup
or after a normal shutdown. To restore power after an unplanned shutdown, see
“Restoring power after an unexpected shutdown” on page 136.
Important:
1. If needed, remove the front bezel, as described in “Removing and replacing the
front bezel” on page 130.
2. Ensure that all power cords are connected, as described in “Connecting the
power cables” on page 122.
2. You can also make out-of-band management connections to the DS5100 and DS5300 controller using the default IP addresses.
The default IP addresses for the controller A Ethernet ports 1 and 2 are 192.168.128.101 and 192.168.129.101, respectively. The
default IP addresses for the controller B Ethernet ports 1 and 2 are 192.168.128.102 and 192.168.129.102, respectively. The
default subnet mask for all four Ethernet ports is 255.255.255.0.
