Note: A PoE Power Injector may be convenient for providing local power when
initially configuring the device before installation. These HPE power injectors are
recommended for use with the switch: J9867A HPE Single-Port 802.3at Gigabit PoE
In-Line Power Supply and J9407B HPE 1-port Power Injector (802.3af PoE power).

▌Accessing the switch for the first time

The switch device has a Web-based interface, and also has a Command Line
Interface (CLI) accessible through the console port or via Telnet.

The Web-based interface is accessible from a Web browser using the device’s
assigned IP address.

Access to the CLI via the console port requires a console cable (purchased
separately) and requires that the unit not be fully installed as the console port is on
the back of the switch.

To Telnet to the device and use the CLI also requires knowledge of the device’s
assigned IP address.

Here are three common scenarios for initial switch configuration:

• Install device on a network with a DHCP Server and configure the device from its

Web interface or Telnet CLI.

• Install device on a network without a DHCP Server and configure the device from

its Web interface or Telnet CLI.

• Configure the device from its console port.

Installing device on a network with a DHCP Server and configuring
the device from its Web interface or Telnet CLI

NOTE:

For security purposes, Hewlett Packard Enterprise recommends that you
change the login information and assign access permissions immediately after
the first successful login.

Power the switch and attach it to a network with a DHCP Server.

By default, HTTP and HTTPS are enabled.

By default, the switch is configured to get its IP address from a DHCP server.

You will need to determine the assigned IP address. Here are common methods:

• Go to the DHCP Server and identify the new switch and its assigned address.

Note: Sometimes the DHCP Server is a service of a specific device, such as a
network router or switch with this capability.

• Use the HPE Network Discovery Tool downloadable from Hewlett Packard

Enterprise website. This free utility will scan your network and identify the switch
and its assigned IP address.

12

To log in to the Web interface:

1. Use an Ethernet cable to connect the PC or the configuration terminal to an

Ethernet port on the device.

2. Assign the login host an IP address in the same subnet as the device.

3. Open the browser, and then enter login information:
a. In the address bar, enter the IP address of the device.

− HTTP access—http://ip-address

− HTTPS access—https://ip-address

The ip-address argument represents the IP address of the device.

b. On the login page, enter the default username (admin) and leave blank the

password line. You do not need to enter a password at the first login.

c. Click Login.

For more information about how to Telnet CLI, see HPE FlexNetwork NJ5 000 5G
PoE+ Walljack Switch Getting Started Guide.

Install the device on a network without a DHCP Server and
configure the device from its Web inte rface or Telnet CLI

1. Use an Ethernet cable to connect the PC or the configuration terminal to an

Ethernet port on the device.

2. Identify the IP address and mask of the device.

If the device is not connected to the network, or no DHCP server exists on the
network, the device uses the default IP address and mask. The default mask is

255.255.0.0. The default IP address is 169.254.xxx.xxx, where xxx.xxx depends

on the last two bytes of the MAC address. Find the MAC address label on the
device and use the following rules to determine the last two bytes for the IP
address:

Last two bytes of the MAC address Last two bytes for the IP address

All 0s 0.1

All Fs 255.1

Not all 0s or all Fs

Decimal values of the last two bytes
of the MAC address

For example:

13

MAC address IP address

08004E080000 169.254.0.1

08004E08FFFF 169.254.255.1

08004E082A3F

169.254.42.63 (The decimal value of 2A is 42.
The value of 3F is 63.)

3. Assign the login host an IP address in the same subnet as the device.

4. To access the device from a Web browser, open the browser, and then enter

login information:

a. In the address bar, enter the IP address of the device.

− HTTP access—http://ip-address

− HTTPS access—https://ip-address

The ip-address argument represents the IP address of the device.

b. On the login page, enter the default username (admin) and leave blank the

password line.
You do not need to enter a password at the first login.

c. Click Login.

Note: Console cable is not provided with the switch. The console cable 5184-6719 is
shipped with many HPE products, such as HPE 1620, HPE 19XX, HPE 5120SI, HPE
5130EI switches. The part can also be purchased separately on HPE parts store
PartSurfer.

The following example shows the procedure to connect a PC to the switch:

1. Connect the DB-9 female connector of the console cable to the serial port of the

PC.

2. Connect the RJ-45 connector to the console port.

▌Setting the operation mode

The switch can operate in managed mode (the default) or unmanaged mode.

You can change the switch operation mode by using one of the following methods:

• Use the reset button to change the operation mode.
a. Insert a pin or paper clip into the reset button hole.
b. Press and hold the button for 7 to 12 seconds until the management mode

LED flashes (10 times per second).

c. Release the button. The management mode LED enters the target mode. If

the LED is on, the switch operates in managed mode. If the LED is off, the
switch operates in unmanaged mode. After the operation mode is changed,
the switch starts saving configuration files. During the saving process, the
Power LED flashes once per second and the reset button is unavailable for
other operations. After the saving process is completed, the Power LED
stops flashing.

NOTE:

To prevent damages to the flash memory, only the first 10 mode change
operations after the reboot can cause configuration saving.

• Connect to the console port of the switch and execute the following commands at

the CLI:

16

<HPE> system-view
[HPE] manage-mode on /* Managed mode */
[HPE] undo manage-mode on /* Unmanaged mode */

When the switch operates in unmanaged mode, you cannot configure the switch.

When the switch operates in managed mode, you can configure the switch at the CLI
or the Web interface. Hewlett Packard Enterprise recommends that you use the Web
interface.
