6N20xx Series Overview

Console Port
The console port provides serial communication capabilities, which allows communication using the RS-232 protocol. The serial port
provides a direct connection to the switch and allows access to the command line interface (CLI) from a console terminal connected to
the port through the provided serial cable.
The console port is separately configurable and can run as an asynchronous link from 1,200 baud to 115,200 baud.
The Dell CLI only supports changing the speed. The defaults are 9600 baud rate, 8 data bits, No Parity, 1 Stop Bit, No Flow Control.
USB Port
The Type-A, female USB port supports a universal serial bus (USB) 2.0-compliant flash memory drive. The Dell Networking switch can
read or write to a flash drive formatted as FAT-32. You can use a USB flash drive to copy switch configuration files and images between
the USB flash drive and the switch. You can also use the USB flash drive to move and copy configuration files and images from one switch
to other switches in the network.
The USB port does not support any other type of USB device.
Reset Button
The reset button is accessed through the pinhole and allows you to perform a hard reset on the switch. To use the reset button, insert an
unbent paper clip or similar tool into the pinhole. When the switch completes the boot process after the reset, it resumes operation with
the most recently saved configuration. Any changes made to the running configuration that were not saved to the startup configuration
prior to the reset are lost.
Port and System LEDs
The I/O-side contains LED that indicate the status of port links, power supplies, fans, stacking, and the overall system status.
Stack Master LED and Stack Number Display
When a switch within a stack is the master unit, the stack master LED, which is labeled M, is solid green. If the M LED is off, the stack
member is not the master unit. The Stack No. panel displays the unit number for the stack member. If a switch is not part of a stack (in
other words, it is a stack of one switch), the M LED is lit, and the unit number displays.

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 support the weight of the switch and the switch
cables. The switch is includes four self-adhesive rubber pads.
1 Attach the self-adhesive rubber pads on each location marked on the bottom of the switch.
2 Set the switch on a flat surface. 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 on N20xx Series Switches
This section explains how to stack multiple N20xx series switches.
Stacking Multiple N20xx Switches on Dell Networking OS
6.3(0.16)
If you are using Dell Networking OS version 6.3(0.16), you can stack up to 12 switches using the mini-SAS ports located on the rear of the
switch. N20xx switches support stacking only with other N20xx series switches. When you connect multiple switches together through
the stack ports, they operate as a single unit with up to 576 I/O-side ports. The stack operates and is managed as a single entity.
NOTE: If you are installing a stack of switches, you must assemble and cable the stack before powering up and configuring it.
When you power up a stack for the first time, the switches elect a Master Switch, which may occupy any location in the stack.

12 N20xx Series Installation

Stacking Multiple Switches on Dell Networking OS 9.11(0.0)
The system supports PE stacking, which allows multiple units to act as a single port extender. You can stack up to eight units using the
stack ports on the PSU-side.
The stack ports support the serial attached SCSI (SAS) protocol and operate as mini-SAS ports. The system supports stacking only with
port extenders of the same series. The stack operates and is managed as a single entity.
NOTE: If you are installing a stack, assemble and cable the stack before powering it up. When you power up a stack for the first
time, the units receive the provisioned configuration from the parent C9010. A Stack Master unit is elected based on the highest
MAC address or highest provisioned priority. The master unit may occupy any location in the stack. The Stack Master LED on
the I/O-side lights on the master unit.
NOTE: Although individual stack members do not require a separate uplink to a parent C9010, Dell Networking recommends
connecting more than one stack unit to the C9010 for redundancy. A stack unit uses the stacking connection to the master PE
for its C9010 uplink. For more information, see the Connecting to a C9010 Switch section.
Creating a Switch Stack
Create a stack by connecting adjacent units using the mini-SAS stacking ports on the PSU-side of the switch. Figure 8 shows the
switches connected in a ring topology. A ring topology is the recommended topology for a stack..
1 Connect one of the mini-SAS cables into either of the stacking ports of the top switch and the switch directly below it.
If necessary, use a separately purchased, longer (1–meter or 3–meter) mini-SAS cable to connect the switches.
2 Repeat this process until you connect all the devices.
3 Use the remaining stacking cable to connect the two remaining stacking ports together to create the ring topology.
Figure 8. Connecting a Stack of Switches
N20xx Series Installation 13

1 Stack units
2 Stacking cables
The ring topology stack has the following physical connections between the switches:
• The bottom mini-SAS port on Unit 1 is connected to the top mini-SAS port on Unit 2.
• The bottom mini-SAS port on Unit 2 is connected to the top mini-SAS port on Unit 3.
• The bottom mini-SAS port on Unit 3 is connected to the top mini-SAS port on Unit 1.
Stacking Standby on Dell Networking OS 6.3(0.16)
The stacking feature on Dell Networking OS version 6.3(0.16) supports a Standby or backup unit that assumes the Master unit role if the
Master unit in the stack fails. As soon as a Master failure is detected in the stack, the Standby unit initializes the control plane and enables
all other stack units with the current configuration. The Standby unit maintains a synchronized copy of the running configuration for the
stack. The Standby unit is automatically selected in the stack; however, you can use the CLI to select a different stack member as
Standby. For more information, see the User's Configuration Guide or the CLI Reference Guide.
Stacking Standby on Dell Networking OS 9.11(0.0)
If the system runs Dell Networking OS version 9.11(0.0), the system supports a Standby or backup unit that assumes the Stack Master
role if the Master unit in the stack fails. The parent C9010 maintains a synchronized copy of the running configuration for the stack. When
the system detects a Stack Master failure, the C9010 initializes the Standby unit and enables all other stack units with the current
configuration.
Although the Standby unit is automatically selected in the stack, you can use the CLI on the C9010 or the N20xx/N30xx series system
console to manually configure a different stack member as Standby. For more information, see the Dell Networking Configuration Guide
for C9000 Series Switches
14 N20xx Series Installation

Starting and Configuring the N20xx Switch
Connecting an N20xx Switch to a Terminal
After completing all external connections, connect a terminal to a switch to configure the switch.
NOTE: Read the Release Notes for this product before proceeding. Dell Networking recommends that you obtain the most
recent version of the user documentation from the Dell Support website at http://www.dell.com/support.
To monitor and configure the switch using the serial console, use the console port on the I/O-side of the switch. Connect it to a VT100
terminal or to a computer running VT100 terminal emulation software. The console port is a data terminal equipment (DTE) connector.
You must have the following equipments to use the console port:
• VT100-compatible terminal or a computer with a serial port running VT100 terminal emulation software, such as Microsoft
HyperTerminal.
• A serial cable (provided) with an RJ-45 connector for the console port and DB-9 connector for the terminal.
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 9600 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 on the right side
of the I/O-side and is labeled with a |O|O| symbol.
NOTE: Serial console access to the Stack Manager is available from any serial port using the local CLI. Only one serial
console session at a time is supported.

Booting the N20xx Switch
When you turn on the power with the local terminal already connected, the switch goes through a power-on self-test (POST). POST runs
every time the switch initializes and checks the hardware components to determine if the switch is fully operational before booting. If
POST detects a critical problem, the program flow stops. If POST passes successfully, valid firmware loads into RAM. POST messages
display 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 completes. From the Boot menu, you can perform configuration tasks such
as resetting the system to factory defaults, enabling the backup image, or recovering a password. For more information about the Boot
menu functions, see the CLI Reference Guide.
Initial Configuration
This section describes how to perform the initial configuration on your system.
Perform the Initial Configuration on Dell Networking OS
6.3(0.16)
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 is established, and the Dell Easy Setup Wizard prompt appears on the screen of a VT100 terminal or terminal
equivalent.
Perform the initial switch configuration 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 pre-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 assign to the management interface.
Starting and Configuring the N20xx Switch 17

• 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).
Enable Remote Management
On the N20xx switches, you can use any of the switch ports on the I/O-side for in-band management. By default, all in-band ports are
members of virtual local area network 1 (VLAN 1)..
The Dell Easy Setup Wizard includes prompts to configure network information for the VLAN 1 interface on the N20xx switch. You can
assign a static IP address and subnet mask or enable the dynamic host configuration protocol (DHCP) and allow a network DHCP server
to assign the information.
For information about the CLI commands you use to configure network information, see the CLI Reference Guide.
Initial Configuration Procedure
You can perform the initial configuration using the Dell Easy Setup Wizard or 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 are
discarded, and the switch uses the default values.
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, see the CLI Reference Guide. This installation guide
describes 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 simple network management protocol (SNMP)community string the SNMP manager uses at a given IP address. You may
choose to skip this step if you do not use SNMP management 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.
Example Session
This section describes a Dell Easy Setup Wizard session. The example session uses the following values:
• The SNMP community 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 wizard configures the initial values. After completing the wizard, the switch is configured as follows:
• SNMPv2 is enabled and the community string is set up. 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.
18 Starting and Configuring the N20xx Switch

• An IP address is configured for the VLAN 1 routing interface.
• A default gateway address is configured.
In the following example, the possible user options or default values are enclosed in [ ]. If you press Enter without defining options, the
default value is accepted. Help text is in parentheses.
Performing Initial Configuration on Dell Networking OS
9.11(0.0)
Before proceeding, ensure that the C9010 switch runs Dell Networking OS version 9.11(0.0) or later.
The following section explains the procedure to set up an N20xx switch if it runs the Dell Networking OS version 9.11(0.0) or later:
To complete the hardware installation, install the system in a rack, attach an uplink cable to a parent C9010 switch, set up an N20xx stack
if required, and power on the port extender.
To provision an N20xx system, configure basic software settings from the C9010 console either before or after you connect the N20xx to
a C9010. For example, you can preconfigure software settings to download from the parent C9010 after you power on the N20xx.
Provisioning preconfigured N20xx settings is performed using a discovery and authentication process through a port-channel interface on
the C9010.
The C9010 port-channel interface enabled for port extender (PE) communication consists of member ports configured with the cascade
port command. For more information, see the Provisioning a Port Extender section.
Provisioning a Port Extender
You can provision an N20xx system with an initial software configuration before or after you install and power on the PE. To provision an
N20xx system, start from the C9010 console and enter the following commands. If you enter the commands before you install the N20xx
system with a parent C9010, the preconfigured software settings download to the N20xx system when you attach it to a C9010 port and
power it up.
NOTE: Although you can provision an N20xx system after you install and power it on, Dell Networking recommends
preconfiguring the software provisioning before you install it. Then connect the N20xx system to a preconfigured, cascaded
C9010 port. In this way, you can “plug and play” an N20xx system with a parent C9010.
1 Turn on the port-extender feature on a C9010.

Dell(conf-pe-0)# stack-unit unit-id type unit-type
•unit-id is a stack-unit ID number from 0 to 7. The default value is 0.
•unit-type is a stack-unit type.
4 Provisioning an N20xx system automatically creates a link aggregation group (LAG) on the C9010. The C9010 LAG member ports are
the cascade ports configured for the PE with the cascade interface command. The cascade ports must be operationally up
(no shutdown command) and have a default port configuration with no L2 and L3 configuration. The port interfaces must be the
same type. You can configure up to eight C9010 ports in the auto-LAG. The generated auto-LAG number is from 257 to 513.

•slot/port-range specifies a C9010 10 GbE port, including slot number and either a single port number, a port range, or a
combination of both for auto-LAG configuration.
• The range of slot numbers is from 0 to 11. In line-card slots 0 to 9, the range of port numbers is from 0 to 23; in RPM slots 10
and 11, the range of port numbers is from 0 to 3.
• Enter a port range with or without spaces; for example, cascade interface tengigabitethernet 0/1-5 or
cascade interface tengigabitethernet 0/1 - 5.
• You can enter up to six comma-separated ranges or port numbers; for example, cascade interface
tengigabitethernet 0/1-2,8,10–12,15.

NOTE: If the status of a port extender is error, communication with an attached C9010 was unsuccessful, possibly due to a
mismatch in software version (SVM) or another communication error. Wait five minutes for an autoupgrade of the port extender
to complete. If the status does not change to online, contact Dell Networking Support for assistance.
