16.3.8. Discover Out-of-Band Management IP Address¶
There are a variety of ways to determine the IP address that is being used by the X10 Out-of-Band management interface.
16.3.8.1. Preset¶
If the system was preconfigured by iXsystems, the Out-of-Band management interfaces have already been configured with the IP addresses requested by the user.
Otherwise, the Out-of-Band management IP addresses are set by default to static addresses:
Node 1: 192.168.100.100, subnet mask 255.255.255.0
Node 2 (if present): 192.168.100.101, subnet mask 255.255.255.0
16.3.8.2. DHCP¶
If the Out-of-Band management IP address has been configured to be assigned by DHCP, the IP address assigned by the DHCP server can be determined by checking the local DHCP server logs for the MAC addresses on the back panel of each X10 node, #11 on Figure 16.3.2.
The local DHCP server can also be configured to provide a fixed IP address for the X10 Out-of-Band management by using the MAC address.
16.3.8.3. Serial Cable¶
The Out-of-Band management IP address can be identified or changed by temporarily connecting the black USB serial cable to the Out-of-Band serial port, #5 on Figure 16.3.2. Connect the USB end of the black cable to a laptop or desktop computer running serial terminal software.
Do not use the serial port for any purpose except checking the initial X10 Out-of-Band management IP address or setting that address to be obtained by a different method. After use, disconnect the black USB serial cable from the X10.
16.3.8.3.1. Out-of-Band Serial Terminal Communication Settings¶
Serial Port Device Names
The name of the serial port varies with operating systems. These are some typical examples:
- Windows:
COM4- macOS:
/dev/tty.usbserialxynnn- FreeBSD:
/dev/cuaU0- Linux:
/dev/ttyUSB0
Serial Port Communication Parameters
Set the serial terminal program to use the appopriate port with these parameters:
38400 baud, 8 data bits, no stop bits, no parity, no flow control
Log in to the serial console with:
Username: sysadmin
Password: superuser
The current Out-of-Band management IP address is displayed with:
ifconfig eth0 | grep 'inet addr'
inet addr:10.20.1.227 Bcast:10.20.1.255 Mask:255.255.254.0
The current Out-of-Band network configuration settings are displayed with:
ipmitool -H 127.0.0.1 -U admin -P admin lan print
The Out-of-Band management system can be set to obtain an IP address from DHCP with:
ipmitool -H 127.0.0.1 -U admin -P admin lan set 1 ipsrc dhcp
The Out-of-Band management system can be set to use a static IP address and netmask. This example shows setting the IP address to 192.168.100.100 with a netmask of 255.255.255.0:
ipmitool -H 127.0.0.1 -U admin -P admin lan set 1 ipsrc static
ipmitool -H 127.0.0.1 -U admin -P admin lan set 1 ipaddr 192.168.100.10
ipmitool -H 127.0.0.1 -U admin -P admin lan set 1 netmask 255.255.255.0

With two people, place the back of the expansion shelf on the rack. Gently push it backwards until the front panels of the expansion shelf are pressed against the front of the rack.
Secure the expansion shelf to the rack by pushing down and tightening the two built-in thumbscrews as indicated in Figure 16.6.6.
Fig. 16.6.6 Secure E24 Expansion Shelf to the Rack
Once the E24 expansion shelf is secured into the rack, insert the included hard drives. To insert a drive, release the handle with the tab on the right side, push it into the drive bay until the handle starts to be pulled back, and then push the handle the rest of the way forward to secure the drive in place.
To connect the E24 expansion shelf to the TrueNAS® Storage Array, note the labels on the SAS ports on the back of the TrueNAS® Storage Array and the letter label on the back of the expansion shelf. Using the included SAS cables, connect the left In SAS port of the left side expander on the E24 expansion shelf to the SAS port with the same letter on the TrueNAS® Storage Array’s primary storage controller, the one in the top slot. If a secondary storage controller is installed, connect the left In SAS port of the right side expander to the port with the same letter on the secondary storage controller. Refer to Figure 16.6.7 for a detailed view.

Note
Please retain the second SAS cable even when only one controller is installed. If the TrueNAS® system is upgraded later with a second storage controller, the second cable will be needed to connect the E24 expansion shelf.
Before plugging in and powering on the E24 expansion shelf, make sure the power switches on both power supplies are set to the Off (Circle) position shown in Figure 16.6.8. Using the power cables provided, connect both power supplies to appropriate power sources. Secure the power cables in place with the plastic locks.

Once all the power and storage connections are set up, turn on the expansion shelf by moving the power switches on both power supplies to the On (line) position.
When setting up a TrueNAS® Storage Array for the first time, wait two minutes after powering on all expansion shelves before turning on the TrueNAS® Storage Array.
