Drawing 1X00508 Section 1: Introduction
The 1X00508 drawing identifies each switch by a unique group number:
Group Application G01 IP switch G02 Root switch, zero fan-out switches supported G03 Back-up root switch, zero fan-out switches supported, G04 Primary fan-out switch G05 Partner or Secondary fan-out switch G06 Root switch, up to 3 pairs of fan-out switches supported G07 Back-up root switch, up to 3 pairs of fan-out switches supported G08 Root switch, up to 10 pairs of fan-out switches supported G09 Back-up root switch, up to 10 pairs of fan-out switches supported G10 Dual Attached -- IP traffic only switch G11 Manageable Field LAN / IO switch G12 Root switch, 1 pair of fan-out switches supported G13 Back-up root switch, 1 pair of fan-out switches supported G42 “Spare” – prepared for field configuration to replace a G01 through G13 switch G99 Base switch, all other groups are made from this one.
As indicated in the table above, all groups except G42 and G99 are fully configured switches for use in an Ovation DCS.
G99 is the “base switch” from which all other groups are to be made. G99 is an un-configured switch that has been inspected and upgraded as necessary to insure that it has the correct Cisco IOS software and cautionary labeling installed.
G42 is a G99 that is prepared for field configuration to replace groups G01 through G13.
1.1 PC Preparation
The reader is assumed to be familiar with the PC environment, including the ability to use both serial and Ethernet communications facilities.
The procedures described below require a PC with a terminal emulator such as
HyperTerminal™. The following settings and commands assume that HyperTerminal is being used.
The COM port should be set to 9600 baud, 8 data bits, no parity, 1 stop bit, and no flow control. Advanced terminal settings such as line delay and character delay may need to be adjusted if the switch configuration download results in errors or partial configuration due to overrun errors on the switch command parser (try line delay = 10msec and character delay = 2msec as a starting point).
Initial communication with the switch is done through the switch’s CONSOLE port.
Cisco supplies a powder-blue modular cable with either an integral DB-9 connector or a separate gray DB-9 to modular adapter with each switch. This cable should be used to Release 01

Drawing 1X00508 connect the port labeled “CONSOLE” on the switch to the serial DB-9 COM port on the PC.
Upgrading switch software requires a TFTP-server application and use and re-configuration of the PC’s Ethernet adapter.
The SolarWinds™ TFTP Server1 for Windows 95, 98, NT, ME, Win2K, and XP is included with this release.
The TFTP server is a self-installing executable. Open SolarWinds-TFTP-Server.exe and follow the on-screen instructions. Accepting the defaults will install the software in the \"C:\\Program Files\\SolarWinds\\\" sub-directory, add a “Start” menu selection, and create the directory “C:\\TFTP-Root\\”.
Copy the switch software file c2960-lanbasek9-tar.122-40.SE.tar to the TFTP server root directory “C:\\TFTP-Root\\”. If the TFTP server is already installed, the location of the TFTP server root directory can be determined by starting the TFTP server
application. The TFTP Server root directory is displayed in the status window at the lower left.
1.2 Switch Replacement
If this switch is being configured to replace a 1X00508, 1X00093, or 1X00036 switch in an existing Ovation system, refer to the accompanying document
SwitchReplacement.pdf, which can be found on the CD enclosed with the G42 switches.
Cisco no longer supplies a TFTP server for upgrading switch and router IOS images. SolarWinds.Net, Inc. develops and markets an array of network management, monitoring, and discovery tools. Their TFTP Server is included in this release with their express permission. It and their suite of other network tools are available at http://www.solarwinds.net.

Drawing 1X00508 Section 2: Switch Configuration – Groups 01 to 13
This procedure requires a G99 or G42 base switch as the starting point. Before
beginning this procedure the switch should be visually inspected for the following labels: A warning notice similar to that shown below should be located on the top surface of the switch.
An IOS label, shown below, should be located on the back of the switch and read as indicated:
IOS 12.2(40)SE
NOTE: If either of these labels is missing or if a different IOS is indicated the switch may not be configured correctly as a G99. “Section 3: Base Switch Configuration – G99” procedure must be applied first.
Configuration of Groups 01 through 13 require a system dependant configuration file for each switch. The \"Network Configuration Tool\" available on the Crossroads Intranet site should be used to assign values and build the configuration files. The Network Configuration Tool emails the completed files to the project engineer, the Software Licensing Group, and the Operation technician responsible for switch configuration.
1. The system dependant switch configuration files may be copied to the PC’s hard
drive or loaded directly from floppy diskette or CD-ROM. 2. Perform the procedure described in “Section 4: Verifying Switch Operation:” and return here to continue with configuration of Groups 01 through 13. Make sure the switch responds with the autoinstall and configuration dialog questions. 3. The SW Version and SW Image reported by the switch MUST be 12.2(40)SE and C2960-LANBASEK9-M respectively. If this is not the case, perform the
procedure described in “Section 3: Base Switch Configuration – G99” before proceeding. 4. Press ENTER a few times to obtain the switch prompt. If the prompt is “switch>”, type “ena” and press ENTER. The prompt should change to “switch#”. 5. Type “conf t” and press ENTER. The switch will respond with:
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#

Drawing 1X00508 Right click on the HyperTerminal “Transfer” function and select “Send Text File”. Browse for and “Open” the appropriate switch configuration file in the dialog box. Carefully monitor the HyperTerminal text window to insure that commands in the configuration file are being typed into the switch configuration. As each
command is sent to the switch the switch will prompt with the switch name plus “(config)” or “(config-if)”.
During the configuration the switch will also display warning messages, which indicate:
• A command is setting a parameter that has already been set or is the same as the default condition. Examples:
test-switch(config)#vtp mode transparent Device mode already VTP TRANSPARENT. test-switch(config)#no udld enable UDLD is already globally disabled.
• An operating mode change that should be used with caution or does not activate immediately. Example:
test-switch(config-if)# spanning-tree portfast
%Warning: portfast should only be enabled on ports connected to a single host. Connecting hubs, concentrators, switches, bridges, etc... to this interface when portfast is enabled, can cause temporary bridging loops. Use with CAUTION
%Portfast has been configured on FastEthernet0/24 but will only have effect when the interface is in a non-trunking mode.
If the switch displays any error messages indicating invalid input to the command parser, such as:
^
% Invalid input detected at '^' marker.
the switch is failing to receive the commands properly. This usually indicates that the terminal emulator is delivering text to the switch console too rapidly. Try increasing the terminal emulator line and character delay settings to 50 and 10 milliseconds respectively. Power cycle the switch, re-run the terminal emulator with its new settings, and go back to Step 4.
The last command sent to the switch is “end,” completing the transfer. The “end” command will exit the configuration dialog, and the switch will display its command prompt, e.g.,
priswitch#
6. Press ENTER a few times to make sure the switch displays the command prompt. At the command prompt, type “write” and press ENTER. The switch should respond with:
Building configuration... [OK]
priswitch#

Section 3: Base Switch Configuration – G99
The group G99 base configuration establishes a consistent starting point for all of the other switch configuration groups. It also ensures that any switches that are shipped from stock are configured with a valid and approved IOS (switch software) and are dressed with the proper warning and identification labels for use in an Ovation system.
1. Perform the procedure described in “Section 4: Verifying Switch Operation:” and return here.
2. If the switch reports the SW Version is 12.2(40)SE AND the SW Image is C2960-LANBASEK9-M, continue with Step 19 of this procedure.
Caution: When upgrading the IOS, make certain that the switch and PC are securely connected to a reliable source of power.
3. Since the switch is not running the approved software, additional steps must be taken to load the proper version. Be sure that the PC has been properly prepared as described in “1.1 PC Preparation” above.
Note: This procedure requires the PC running the TFTP server have IP connectivity to the switch. It is necessary to configure the PC’s Ethernet adapter to have an IP address on the same subnet as the switch.
Do not connect the PC Ethernet to the switch at this time.
4. Assign the PC’s Ethernet adapter the static IP address of 192.168.2.1 with a subnet mask of 255.255.2.0. Verify that the IP address and subnet mask are set properly. Reboot the PC if required.
5. Re-establish HyperTerm communication with the switch CONSOLE port. Press ENTER a few times to obtain the switch prompt. If the prompt is “switch>”, type “ena” and press ENTER. The prompt should change to “switch#”.
6. At the “switch#” prompt, type “conf t” and press ENTER. The switch should respond with:
Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#
7. Type the following commands, and press ENTER after each line:
no ip http server int vlan1 (The prompt will change to Switch(config-if)#) ip address 192.168.3.1 255.255.2.0 no shutdown end

8. Type “write” and press ENTER at the “Switch#” prompt. The switch should
respond with:
Building configuration... [OK] Switch#
9. Connect the PC’s Ethernet adapter to port 1 on the switch with a straight-through patch cable. The switch port LED should first turn amber and then, after 15 to 30 seconds, green. The LED must be solid green before proceeding with the upgrade process. You should see the following messages displayed from the switch CONSOLE port:
xx:xx:xx: %LINK-3-UPDOWN: Interface FastEthernet0/1, changed state to up
xx:xx:xx: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up
10. From a DOS Command shell on the PC, use the “ping 192.168.3.1” command to verify IP connectivity to the switch. Do not proceed unless the switch responds to the ping.
11. Activate the TFTP server application.
12. At the “Switch#” prompt, type the following command and press ENTER.
archive download-sw /overwrite tftp://192.168.2.1/c2960-lanbasek9-tar.122-40.SE.tar
The tftp download will begin with the switch displaying text similar to the following: Loading c2960-lanbasek9-tar.122-40.SE.tar from 192.168.2.1 (via Vlan1): !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

NOTE: There are two common errors that can cause the tftp download to abort immediately:
• If the switch responds with “Could not buffer tarfile…”, this
indicates the TFTP server could not locate the file requested by the switch. Verify that the file c2960-lanbasek9-tar.122-40.SE.tar was copied correctly to the TFTP server root directory. Release 01

If the switch responds with error messages starting with: ‘Unable to create temp dir “flash:update”’ or
‘Error opening flash:update/info’,
this indicates a previous tftp upgrade did not complete successfully. At the “Switch#” prompt, enter:
delete /r /f flash:update
and press “ENTER” to confirm directory removal when prompted.
Re-enter the “archive…” command as above at the “Switch#” prompt to initiate the tftp download.
