Welcome to the ERS4900 setup utility.
You will be requested to provide the switch basic connectivity settings. After entering the requested
info, the configuration will be applied and stored into the switch NVRAM.
Once the basic connectivity settings are applied, additional configuration can be done using the available
management interfaces. Use Ctrl+C to abort the configuration at any time.

Manual configuration
Use the following CLI command to manually configure the in-band management IP address:
ip address <A.B.C.D> [netmask <A.B.C.D>] [default-gateway <A.B.C.D>]
Example:
1.
Enter Privileged Exec mode:
4900GTS>enable
2.
Enter the Global Config mode:
4900GTS#config terminal
3.
Manually configure in-band management IP information:
4900GTS(config)#ip address 192.0.2.1 netmask 255.255.255.0
default-gateway 192.0.2.0

Connect stacking cables as required for a Cascade Up (stack up) or Cascade Down
(stack down) configuration as shown below:
Connect the AC power cord to the back of the switch, and then plug the other end of the cord
into an AC power outlet.
Warning:
You must use a power cord set approved for the 4900 Series switch and the power
receptacle type in your country.
Ensure you have properly grounded the switch before powering up the unit.
The console port uses the RJ-45 port outlined with a blue border. Use an RJ-45 to DB-9 cable, or a
DB-9 to DB-9 serial cable to connect the switch console port to your management terminal.
Adapters are available to provide different connection options. The maximum length of a console
cable is 25 feet (8.3 meters). The following table describes the RJ-45 console port pin-out
information. You can use the pin-out information to verify or create a console cable for use with
your maintenance terminal.
1.
Connect the console cable from the terminal to the console port of the switch to allow
initial configuration. Any terminal or PC with the appropriate terminal emulator can be
used as the management station.
2.
Set the terminal protocol on the terminal or terminal
emulation program to VT100 or VT100/ANSI.
3.
Connect to the switch using the terminal or terminal
emulation application.
4.
The switch banner appears when you connect to the
switch through the Console port. There is no default
password for the switch for CLI console access.
Enter
Ctrl+Y
and type the following CLI commands:
enable
install
5.
The CLI Quickstart welcome screen helps you enter the information requested at each prompt.
Note:
The ERS 4900 uses the default IP address of 192.168.1.1/24 if the switch does
not get its IP address from another source. The default IP address is not applicable to
the out-of-band management port.
RJ–45 Console port pin assignments
The switch will power on immediately when it is connected to a suitable AC power source. The
switch does not have a power switch.
Check the front-panel LEDs as the device powers on to be sure the PWR LED is lit green. If not,
check if the power cord is correctly connected.
Status LEDs are on the left front side of the switch. For more information on all status LEDs, see
Installing ERS 4900 Series.
Before installing SFP and SFP+ transceivers, ensure the switch is up, fully booted, and operating
normally. Verify that the SFP or SFP+ transceivers and network cabling support your network
configuration.
Install SFP transceivers by performing this procedure.
1.
Remove the transceiver from the protective packaging.
2.
Verify that the transceiver is the correct model for the
network configuration.
3.
Grasp the transceiver between your thumb and forefinger.
4.
Insert the transceiver into the proper module on the switch.
Apply a light pressure to the transceiver until it clicks and
locks into position in the module.
