Device introduction

Data Transport II device

Picture
The front, rear, and top panels of a Data Transport II device can be opened. The front and rear panels can open 90 degrees and lay flat. This way, you can push them horizontally to stow them underneath the device. The device is equipped with four optical transceiver modules, including two 10 Gbit/s modules and two 25 Gbit/s modules, and one power cord that follows China national standards. The power cord can be found after you open the top panel. You can place the device vertically or horizontally based on the rack space.

No.	Description
1	Six USB 3.0 ports, which can be used to connect to mouses, keyboards, and hard disks.
2	The power button.
3	Two 10 Gbit/s optical ports.
4	Two 1 Gbit/s copper Ethernet ports. The two ports are 1G NIC 1 and 1G NIC 2. The 1G NIC 2 port functions as the management port and the management IP address is `10.10.1.1`.
5	Two 25 Gbit/s optical ports.
6	The Video Graphics Array (VGA) port, which can be used to connect to a monitor.
7	The out-of-band management port.

Note

We recommend that you do not use the management port as a service port.

Step 1: Mount the device on a rack

Unpack and inspect the device.
When you receive a Data Transport II device, you must check the integrity of the device and accessories. The accessories include four optical transceiver modules, which are two 10 Gbit/s modules and two 25 Gbit/s modules, and one power cord that follows China national standards. The power cord can be found after you open the top panel of the device. Then, check whether the device is damaged. If the device is damaged, contact Alibaba Cloud technical support.
Mount the Data Transport device on a rack.
The Data Transport II device is not a standard rack-mounted device. Before you mount the device on a rack, you must prepare a rail and a tray for installation. You can also place the device at the bottom of the rack.
Use a power cord to connect the device based on the power socket of the rack. The power cord and power socket must follow the same standards, such as American standards or China national standards.
Check data ports.
The device board has 1 Gbit/s ports. If you want to use the 10 Gbit/s or 25 Gbit/s network, make sure that small form-factor pluggable (SFP) modules are installed.
After you use the power cord to connect the device, press the power button to power on the device and check the running status.

Connection methods

The Data Transport II device can be connected by using the following methods:

Use a network switch.
Use an Ethernet cable.

Step 2: Configure the service IP address

Method 1

The default management IP address of the Data Transport II device is 10.10.1.1, and the subnet mask is 255.255.255.0.

Use an Ethernet cable to connect your laptop to the management port of the Data Transport II device. The Data Transport II device has two 1 Gbit/s copper Ethernet ports. The 1G NIC 2 port functions as the management port and the management IP address is 10.10.1.1.
Modify the local IP address of the laptop. The new IP address of the laptop and the management IP address of the device must belong to the same CIDR block. For example, change the local IP address to 10.10.1.2 and the subnet mask to 255.255.255.0.
Note
If the management IP address of the device is not 10.10.1.1, use Method 2.
Open the CLI, enter ssh root@10.10.1.1, and then press the Enter key.
Enter the username and password to log on to the Data Transport device.
To obtain the username and password, contact Alibaba Cloud technical support.

Run the cd /etc/sysconfig/network-scripts/ command to go to the specified directory. You can see the following configuration files of the network ports.

Name	Description
ifcfg-eno1	The configuration file of the 1G NIC 1 port.
ifcfg-eno2	The configuration file of the 1G NIC 2 port. The 1G NIC 2 port is the management port. Do not modify the configuration file.
ifcfg-eno3	The configuration file of the 10G NIC 1 port.
ifcfg-eno4	The configuration file of the 10G NIC 2 port.
ifcfg-enp7s0f0	The configuration file of the 25 Gbit/s port 1.
ifcfg-enp7s010	The configuration file of the 25 Gbit/s port 2.

Open the corresponding configuration files and then confirm or modify the following parameters based on the network ports of the Data Transport II device.

Parameter	Description
BOOTPROTO	Specify the type of IP address assignment. Set the value to static.
ONBOOT	Specify whether to enable the network interface controller (NIC) when the system is started. Set the value to yes.
IPADDR	Configure the service IP address. Example: 10.10.1.2.
NETMASK	Configure the subnet mask. Example: 255.255.255.0.
GATEWAY	Configure the IP address of the gateway. Example: 10.10.1.1.

Run the service network restart command to restart the network service. If OK is returned, the network service is restarted.

Method 2

Connect a monitor, mouse, and keyboard to the Data Transport device.

Enter the username and password to log on to the Data Transport device.
To obtain the username and password, contact Alibaba Cloud technical support.

Run the cd /etc/sysconfig/network-scripts/ command to go to the specified directory. You can see the following configuration files of the network ports.

Name	Description
ifcfg-eno1	The configuration file of the 1G NIC 1 port.
ifcfg-eno2	The configuration file of the 1G NIC 2 port. The 1G NIC 2 port is the management port. Do not modify the configuration file.
ifcfg-eno3	The configuration file of the 10G NIC 1 port.
ifcfg-eno4	The configuration file of the 10G NIC 2 port.
ifcfg-enp7s0f0	The configuration file of the 25 Gbit/s port 1.
ifcfg-enp7s010	The configuration file of the 25 Gbit/s port 2.

Open the corresponding configuration files and then confirm or modify the following parameters based on the network ports of the Data Transport II device.

Parameter	Description

Run the service network restart command to restart the network service. If OK is returned, the network service is restarted.

Step 3: Check the hard disk status

Before you use the Data Transport II device, you must check the hard disk status. If you find problems in the hard disk or storage pool, contact Alibaba Cloud technical support.

Run the df -h command in the CLI to check the storage pool.
The /mnt/cube directory is the storage directory of the Data Transport device. Save the data in this directory.

Step 4: Check whether the filedata share folder exists

Before you use the Data Transport II device, you must check whether the filedata share folder exists.

Run the showmount -e x.x.x.x command in the CLI.
The following information is returned after you run the command.
