Introduction
This document provides specific procedures for upgrading the Dell™ Networking
N2024/N2024P/N2048/N2048P/N3024/N3024F/N3024P/N3048/N3048P switches to firmware version
6.1.1.7 or later.
IMPORTANT: Dell Networking N2000 and N3000 Series switches support 6.0.1.3
or later firmware (6.1.1.7). Both Dell Networking N2000 and N3000 Series
switches can share the same firmware image version (N3000_N2000v6.1.1.7.stk)
IMPORTANT: Administrators upgrading N2000 and N3000 series switches from
6.x.x.x to 6.1.1.7 of firmware MUST follow the instructions documented in this
procedure. Failure to follow the procedures described in that document when
upgrading from 6.x.x.x to 6.1.1.7 firmware may result in an inoperable switch!
IMPORTANT: After upgrading the switch firmware version to 6.1.1.7, the boot
code update is required on N2000 and N3000 series switches via serial console if
switch is running with the older boot code version. The latest boot code version
available for N2000 and N3000 series switches is “U-Boot SPL 2012.10-00078-
g24e99ea (Jun 24 2014 - 16:41:18)”. Administrators upgrading N2000 and N3000
series switches MUST follow the boot-code update instructions documented in
this procedure.

Upgrade Overview
Administrators must have access to the CLI via telnet, SSH or the serial port to perform the upgrade procedure.
Upgrade Procedure for Dell Networking N2000/N3000 Series Switches
The upgrade procedure given below upgrades an individual switch or a stack of switches running firmware version
6.x.x.x. This is a normal operation of the upgrade procedure. Please do not interrupt switch operation during the
upgrade process as this may result in corruption of flash memory. Do not power off a switch undergoing the
upgrade process unless specifically directed to do so by the instructions.
To upgrade a switch running a 6.x.x.x version of firmware to the 6.1.1.7 version of firmware or later, uses the
procedure below. An annotated upgrade example is shown following this section.
1. Back up your configuration.
2. If using telnet or ssh to perform the upgrade procedure and if the current configuration does not contain a
non-default enable authentication method or enable password, configure an enable password and save the
configuration. Example steps to configure an enable password are shown below:
console#configure
console(config)#enable password <password>
console(config)#exit
console#copy running-config startup-config
3. Download the 6.1.1.7 firmware image (N3000_N2000v6.1.1.7.stk) to the switch or stack master.
NOTE: Activate the image to use as the boot (active) image after the switch
resets. Images on the N2000/N3000 series switches are named active and backup.
4. Activate 6.1.1.7 firmware.
NOTE: Boot Code Update is required for Dell Networking N2000 and N3000
Series Switches after reloading the switch with firmware version 6.1.1.7 as
active image
5. Reload the switch.
6. Update boot code.
7. Reload the switch again for boot code to take effect.
NOTE: A TFTP server must be on the network and the switch software
must be accessible to the TFTP server before attempting to download
the switch software by TFTP.
NOTE: The following TFTP server may be used if you do not have
one: http://tftpd32.jounin.net/tftpd32_download.html

How to Access Serial Console on N2000/N3000 series switches
NOTE: How to access serial console of the N3000 Series switch? Use a supplied “RJ45 Yost to DB9
serial cable” to access the serial console. Connect the RJ45 end of the cable to the RJ45 serial console port
and the DB9 connector to your PC. Download and Install the terminal emulation software on your PC (for
example., PuTTY) to access the serial console with the correct settings (default setting 9600 baud, 8 data
bits, no parity bit, 1 stop bit, and no flow control).

NOTE: How to access serial console of the N2000 Series switch? Use a supplied “RJ45 Yost to DB9
serial cable” to access the serial console. Connect the RJ45 end of the cable to the RJ45 serial console port
and the DB9 connector to your PC. Download and Install the terminal emulation software on your PC (for
example., PuTTY) to access the serial console with the correct settings (default setting 9600 baud, 8 data
bits, no parity bit, 1 stop bit, and no flow control).
NOTE: N2000 switches do not have an out-of-band interface.
Figure.2 N2048 Switch with 48 10/100/1000BASE-T Ports (Front Panel)
RJ-45 serial console port
NOTE: By default, no network information is configured. The DHCP client is enabled on the OOB
interface by default on N3000 and N4000 switches. The DHCP client is enabled on VLAN 1 by default on
the N2000 switches. DNS is enabled, but no DNS servers are configured. VLAN 1 does not have an IP
address, subnet mask, or default gateway configured on N3000 and N4000 switches. You can assign an IP
address or IPv6 addresses to the OOB management port and to any VLAN. By default, all ports are
members of VLAN 1. If you assign an IP address to VLAN 1, you can connect to the switch management
interface by using any of the front-panel switch ports. This is required to manage the N2000 switches over
an Ethernet port.

Upgrade Example for Dell Networking N2000/N3000 Series Switches
This example shows an annotated upgrade example for a N3048 switch running 6.x.x.x firmware. This example
presumes the administrator is logged in to the switch or stack via Serial console. You can also follow this upgrade
procedure via telnet or SSH after setting enable password if it is not set so.
1. Back up your configuration. The following commands copy the running-config to a TFTP server:
console#copy running-config tftp://10.10.10.200/myconfig.txt

2. Set an enable password and save the configuration (not required if an alternative enable authentication
method is already configured).
console#configure
console(config)# enable password <password>
console(config)# exit
console# copy running-config startup-config
3. Download the 6.1.1.7 firmware image from a TFTP server.

10. On switch reload, verify the boot-code version is updated to the latest “U-Boot SPL 2012.10-00078-
g24e99ea (Jun 24 2014 - 16:41:18)” from the serial console.
Stacking Notes
Regarding steps 2, 3 and 4 above:
•The “copy” command will take longer to complete with a stack of switches. This is due to the master
switch copying the software to the member switches. The master switch will display the line “Distributing
the code to the members of the stack!” for several minutes until the copy is done.
•The “copy” command will copy the software to all the switches as “backup” image

After the stack of switches has finished rebooting, log in and verify that the firmware has been updated to the
6.1.1.7 version using the show version command. A single switch will typically reboot in around two minutes. A
stack may take significantly longer to complete the upgrade process.

Switch Recovery Procedure
NOTE: The Switch Recovery procedure requires one to connect to each
switch individually via the serial port. It will not upgrade stack members other
than the switch directly connected via the serial port. If the switches are
connected via stacking cables, disconnect the stacking cables to perform the
recovery procedure.
1. Connect a serial cable to the serial console port on the switch (8-No Parity-1-9600-No Flow Control).
a. Use the supplied RJ45 Yost to DB9 serial cable. Connect the RJ45 end to the switch console port
and the DB9 connector to your PC. Set the terminal emulation software (for example., PuTTY) to
the correct settings (default setting 9600 baud, 8 data bits, no parity bit, 1 stop bit, and no flow
control).

Out-of-Band Management Port
RJ-45 serial console port
2. When the boot menu appears, select 2 – Start Boot Menu within 10 seconds of the prompt appearing. If the
boot menu does not appear after power cycling the switch, check the serial port settings and the serial cable
connections. Make sure that RTS/CTS (HW flow control) and XON/XOFF (SW flow control) are disabled
on the terminal. It is preferred to use the serial cable supplied with the switch. If you do not have the
original serial cable, it may be necessary to use a NULL modem device to access the switch via the serial
cable. Check the serial cable setup with an operational switch to verify that it works properly.
3. Download 6.1.1.7 firmware to the switch using TFTP by selecting option 4 - Load new operational code
from the boot menu.
4. Verify that the firmware has been updated to the 6.1.1.7 version using the show version command.
5. Update Boot Code using the hidden CLI command “update bootcode” from CLI.
