IBM DS3950, Инструкция по установке, использованию и обслуживанию, Страница: 41 / 252

Note: For a storage subsystem that has two Ethernet ports per controller, such
as the DS3950, use the Ethernet port that is labeled #1.
The default IP addresses of the second Ethernet port are:
v
Controller A: 192.168.129.101
v
Controller B: 192.168.129.102
v
Subnet mask: 255.255.255.0
2. Start the DS Storage Manager client software. The Enterprise Management
window opens.
3. Add the DS3950 subsystem to the Enterprise Management domain using the
default IP addresses.
4. In the Enterprise Management window, click the name of the default storage
subsystem. The Subsystem Management window opens.
5.
In the Subsystem Management window, right-click the controller icon and
select
Change > Network Configuration in the pull-down menu. The Change
Network Configuration window opens.
6. In the Change Network Configuration window, click the Controller A and
Controller B tabs and type the new TCP/IP addresses in their applicable fields.
Click
OK .
7. Close the Subsystem Management window, wait at least five minutes, then
delete the default DS3950 storage subsystem entry in the Enterprise
Management window.
8.
If applicable, change the IP address of the Ethernet port in the management
station to a value that is on the same TCP/IP subnet as the controller Ethernet
port IP addresses that you just assigned. Exit DS Storage Manager, then restart.
9. Add a new storage subsystem entry in the Enterprise Management window,
using the new assigned IP addresses.
Note: To manage storage subsystems through a firewall, configure the firewall to
open port 2463 to TCP data.
AC power supply and fan units
The DS3950 storage subsystem has two removable ac power supply and fan units.
Each power supply and fan unit contains one power supply and two fans. The
four fans pull air through the drive from front to back across the drives.
The fans provide redundant cooling, which means that if one of the fans in either
fan housing fails, the remaining fans continue to provide sufficient cooling to
operate the storage subsystem. The power supplies provide power to the internal
components by converting incoming ac voltage to dc voltage. If one power supply
is turned off or malfunctions, the other power supply maintains electrical power to
the storage subsystem. To preserve the optimal airflow, do not remove a failed
power supply and fan unit CRU from the DS3950 chassis until you are ready to
replace it with a new CRU.
Figure 4 on page 14 shows power supply and fan unit components for the DS3950.
Notes:
1.
Your DS3950 hardware might differ slightly from the following illustration.
2. Although both power supply and fan units (left and right) are identical, they
are seated in the DS3950 chassis in opposite orientations. If the power supply
and fan unit cannot fully be inserted in the power supply and fan unit bay, flip
it 180 degree and reinsert it.
