CHAPTER 3: STARTING AND CONFIGURING THE SWITCH
Perform the following tasks to connect a terminal to the switch console port:
1. Connect the USB type B connector on the supplied switch and connect the other end to a computer running VT100 terminal
emulation software.
2. Configure the terminal emulation software as follows:
a. Select the appropriate serial port (for example, COM 1) to connect to the console.
b. Set the data rate to 115,200 baud.
c. Set the data format to 8 data bits, 1 stop bit, and no parity.
d. Set the flow control to none.
e. Set the terminal emulation mode to VT100.
f. Select Terminal keys for Function, Arrow, and Ctrl keys. Make sure that the setting is for Terminal keys (not Microsoft Windows
keys).
3. Connect the USB type B connector on the cable directly to the switch console port. The Networking console port is located on
the right side of the front panel and is labeled with a |O|O| symbol.
NOTE: Console access to the stack manager is available from any console port via the local CLI. Only one USB console session at a
time is supported.
3.2 CONNECTING THE SWITCH TO A POWER SOURCE
CAUTION: Read the safety information in the Safety and Regulatory Information manual as well as the safety information for other
switches that connect to or support the switch.
The EMS1G-48 switches support one or two FRU power supplies. The power receptacle is on the rear panel.
3.2.1 AC POWER CONNECTION
1. Make sure that the switch console port is connected to a PC running a VT100 terminal emulator via the USB to USB Type B cable.
2. Using a 5-foot (1.5 m) heavy-duty power cable with a standard power cable with safety ground connected, connect the power cable to
the AC main receptacle located on the rear power supply.
3. Connect the power cable to a grounded AC outlet.
3.3 BOOTING THE SWITCH
When the power is turned on with the local terminal already connected, the switch goes through a power-on self-test (POST). POST
runs every time the switch is initialized and checks hardware components to determine if the switch is fully operational before
completely booting. If POST detects a critical problem, the program flow stops. If POST passes successfully, valid firmware is
loaded into RAM. POST messages are displayed on the terminal and indicate test success or failure. The boot process runs for
approximately 60 seconds.
You can invoke the Boot menu after the first part of the POST is completed.
From the Boot menu, you can perform configuration tasks such as resetting the system to factory defaults, activating the backup
image, or recovering a password.

CHAPTER 3: STARTING AND CONFIGURING THE SWITCH
3.4 PERFORMING THE INITIAL CONFIGURATION
The initial configuration procedure is based on the following assumptions:
The switch was never configured before.
The switch booted successfully.
The console connection was established, and the Easy Setup Wizard prompt appears on the screen of a PC running terminal
emulation software.
The initial switch configuration is performed through the console port.
After the initial configuration, you can manage the switch from the already connected console port or remotely through an interface
defined during the initial configuration.
NOTE: The switch is not configured with a default user name, password, or IP address.
Before setting up the initial configuration of the switch, obtain the following information from your network administrator:
The IP address to be assigned to the management interface.
The IP subnet mask for the network.
The IP address of the management interface default gateway.
These settings are necessary to allow the remote management of the switch through Telnet (Telnet client) or HTTP (Web browser).
3.4.1 ENABLING REMOTE MANAGEMENT
The front panel of the switch contains a Gigabit Ethernet port for out-of band (OOB) management. The OOB port is located to the right of
the console port. On the switch, you can additionally use any of the switch ports on the front panel for in-band management. By default,
all in-band ports are members of VLAN 1.
The Easy Setup Wizard includes prompts to configure network information for the OOB management interface and the VLAN 1 interface
on the switch. You can assign a static IP address and subnet mask or enable DHCP and allow a network DHCP server to assign the
information.
3.4.2 INITIAL CONFIGURATION PROCEDURE
Perform the initial configuration by using the Easy Setup Wizard or by using the CLI. The wizard automatically starts when the switch
configuration file is empty. Exit the wizard at any point by entering [ctrl+z], but all configuration settings specified will be discarded, and
the switch will use the default values.
NOTE: If you do not run the Easy Setup Wizard or do not respond to the initial Easy Setup Wizard prompt within 60 seconds, the switch
enters CLI mode.
You must reset the switch with an empty startup configuration in order to rerun the Easy Setup Wizard.
For more information about performing the initial configuration by using the CLI, refer to the CLI Reference Guide. This Getting Started
Guide shows how to use the Easy Setup Wizard for initial switch configuration. The wizard sets up the following configuration on the
switch:
Establishes the initial privileged user account with a valid password. The wizard configures one privileged user account during the
setup.
Enables CLI login and HTTP access to use the local authentication setting only.
Sets up the IP address for the OOB management interface.
Sets up the IP address for the VLAN 1 routing interface, of which all in-band ports are members.

After completing the initial configuration described in this section, you can connect the OOB port to your management network
for out-of-band remote management, or you can connect any of the front-panel switch ports to a production network for in-band
remote management.
If you specified DHCP for the OOB interface or for the VLAN 1 management interface IP address, the interface will acquire its IP
address from a DHCP server on the network. To discover the dynamically assigned IP address, use the console port connection to
issue the following command:
For the OOB interface, enter show ip interface out-of-band.
For the VLAN 1 routing interface, enter show ip interface.
To access the OpenManage Switch Administrator interface, enter the OOB management interface IP address into the address
field of a Web browser or enter the VLAN 1 management interface IP address into the address field of a Web browser. For remote
management access to the CLI, enter the OOB management interface IP address or VLAN 1 management interface IP address into
a Telnet or SSH client. Alternatively, continue to use the console port for local CLI access to the switch.
The switch supports basic switching features such as VLANs and spanning tree protocol. Use the Web-based management
interface or the CLI to configure the features your network requires. For information about how to configure the switch features,
refer to the User Configuration Guide or CLI Reference Guide.
