N2128PX-ON Installation
Rack Mounting an N2128PX-ON Switch
WARNING: Read the safety information in the Safety and Regulatory Information
as well as the safety information for other switches that connect to or support the
switch.
The AC power connector is on the rear panel of the switch.
Installing in a Rack
WARNING: Do not use rack mounting kits to suspend the switch from under a
table or desk, or attach it to a wall.
CAUTION: Disconnect all cables from the switch before continuing. Remove all
self-adhesive pads from the underside of the switch, if they have been attached.
CAUTION: When mounting multiple switches into a rack, mount the switches
from the bottom up.
1 Place the supplied rack-mounting bracket on one side of the switch,
ensuring that the mounting holes on the switch line up to the mounting
holes in the rack-mounting bracket. Figure 1-1 illustrates where to mount
the brackets.
Figure 1-1. Attaching the Brackets
2 Insert the supplied bolts into the rack-mounting holes and tighten with a
screwdriver.

10 Getting Started Guide
3 Repeat the process for the rack-mounting bracket on the other side of the
switch.
4 Insert the switch into the 48.26 cm (19 inch) rack, ensuring that the rack-
mounting holes on the switch line up to the mounting holes in the rack.
5 Secure the switch to the rack with either the rack bolts or cage nuts and
cage-nut bolts with washers (depending on the kind of rack you have).
Fasten the bolts on bottom before fastening the bolts on top.
CAUTION: Make sure that the supplied rack bolts fit the pre-threaded holes in the
rack.
NOTE: Make sure that the ventilation holes are not obstructed.
Installing as a Free-standing Switch
NOTE: Dell strongly recommends mounting the switch in a rack.
Install the switch on a flat surface if you are not installing it in a rack. The
surface must be able to support the weight of the switch and the switch
cables. The switch is supplied with four self-adhesive rubber pads.

Attach the self-adhesive rubber pads on each location marked on the
bottom of the switch.
2 Set the switch on a flat surface, and make sure that it has proper
ventilation by leaving 5 cm (2 inches) on each side and 13 cm (5 inches) at
the back.
Stacking Multiple N2128PX-ON Switches
You can stack N2128PX-ON switches up to 12 switches high using the mini-
SAS ports located on the rear of the switch. When multiple switches are
connected together through the stack ports, they operate as a single unit with
up to 336 front panel ports. The stack operates and is managed as a single
entity. Refer to the User Configuration Guide and the CLI Reference Guide for
more information.

12 Getting Started Guide
Connecting an N2128PX-ON Switch to a Terminal
After completing all external connections, configure the switch by connecting
it to a terminal.
NOTE: Read the Release Notes for this product before proceeding. You can
download the Release Notes from the Dell Support website at dell.com/support.
NOTE: Dell recommends that you obtain the most recent version of the user
documentation from the Dell Support website at dell.com/support.
To monitor and configure the switch via serial console, use the console port
on the front panel of the switch to connect it to a VT100 terminal or to a
computer running VT100 terminal emulation software. The console port is
implemented as a data terminal equipment (DTE) connector.
The following equipment is required to use the console port:
• VT100-compatible terminal or a computer with a serial port running
VT100 terminal emulation software,
such as HyperTerminal®.
• A serial cable (provided) with an RJ-45 connector for the console port and
DB-9 connector for the terminal.
Perform the following tasks to connect a terminal to the switch console port:
1
Connect the DB-9 connector on the serial cable to the terminal or
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 RJ-45 connector on the cable directly to the switch console
port. The Dell Networking console port is located on the right side of the
front panel and is labeled with a
|O|O| symbol.

Getting Started Guide 13
NOTE: Serial console access to the stack manager is available from any
serial port via the local CLI. Only one serial console session at a time is
supported.
Connecting an N2128PX-ON 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 N2128PX-ON model has one internal power supply. The power receptacle
is on the rear panel.
AC and DC Power Connection
1 Make sure that the switch console port is connected to a VT100 terminal
or VT100 terminal emulator via the RJ-45 to DB-9 female cable.
2 Using a 5-foot (1.5 m) standard power cable with safety ground connected,
connect the power cable to the AC main receptacle located on the rear
panel.
3 Connect the power cable to a grounded AC outlet.
4 If you are using a redundant or external DC power supply, such as the Dell
Networking RPS720 or Dell Networking MPS1000 (N2128PX-ON only),
connect the DC power cable to the DC receptacle located on the rear
panel.

14 Getting Started Guide
Booting the N2128PX-ON 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. For more information about the Boot menu functions, refer to the
CLI Reference Guide.

Getting Started Guide 15
Performing the N2128PX-ON Initial Configuration
The initial configuration procedure is based on the following assumptions:
• The Dell Networking switch was never configured before.
• The Dell Networking switch booted successfully.
• The console connection was established, and the
Dell Easy Setup Wizard
prompt appears on the screen of a VT100 terminal or terminal equivalent.
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).
Enabling Remote Management
On the N2128PX-ON/N3132PX-ON switches, you can 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 Dell Easy Setup Wizard includes prompts to configure network
information for the VLAN 1 interface on the N2128PX-ON switch. You can
assign a static IP address and subnet mask or enable DHCP and allow a
network DHCP server to assign the information.
Refer to the CLI Reference Guide for commands to configure network
information.

16 Getting Started Guide
Initial Configuration Procedure
Perform the initial configuration by using the Dell Easy Setup Wizard or by
using the CLI. The wizard automatically starts when the switch configuration
file is empty. You can 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 Dell 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 Dell 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 Dell 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 VLAN 1 routing interface, of which all
in-band ports are members.
• Sets up the SNMP community string to be used by the SNMP manager at
a given IP address. You may choose to skip this step if SNMP management
is not used for this switch.
• Allows you to specify the network management system IP address or
permit management access from all IP addresses.
• Configures the default gateway IP address for the VLAN 1 interface.

Getting Started Guide 17
Example Session
This section describes a Dell Easy Setup Wizard session. The following
values are used by the example session:
• The SNMP community string to be used is public .
• The network management system (NMS) IP address is
10.1.2.100 .
• The user name is
admin , and the password is admin123 .
• The IP address for the VLAN 1 routing interface is
10.1.1.200 with a
subnet mask of
255.255.255.0 .
• The default gateway is
10.1.1.1.
The setup wizard configures the initial values as defined above. After
completing the wizard, the switch is configured as follows:
• SNMPv2 is enabled and the community string is set up as defined above.
SNMPv3 is disabled by default.
• The admin user account is set up as defined.
• A network management system is configured. From the management
station, you can access the SNMP, HTTP, and CLI interfaces. You may also
choose to allow all IP addresses to access these management interfaces by
choosing the (0.0.0.0) IP address.
• An IP address is configured for the VLAN 1 routing interface.
• A default gateway address is configured.
NOTE: In the following example, the possible user options or default values are
enclosed in [ ]. If you press <Enter> with no options defined, the default value is
accepted. Help text is in parentheses.
