Upgrading the Flash Image
To perform a field upgrade of a Flash image, follow these steps:
Step 1 Ensure that the IP addresses and the FTP servers, user accounts, path names, and filenames of the Flash
image are correctly set up.
Step 2 Enter show-trap to verify that the trap display is turned on.
Step 3 Enter sw-download ftp server-IP username password path filename flashbank or sw-download tftp
server-IP filename flashbank to FTP (TFTP) the image from the FTP (TFTP) server and burn it to the
specified Flash bank. Make sure that the FTP (TFTP) server is accessible using the same username,
password, path name, and filename.
Note Two traps are generated to indicate the beginning and ending of the FTP burn process. The image
cannot be downloaded to a currently active bank.
Step 4 Once the sw-download ftp process is complete, enter boot-bank flashbank to set the boot bank from
which the system next boots up.
Step 5 Enter reboot to reboot the system.
Configuring Remote Communication
To establish a remote communication link with a Cisco ONS 15501 through Telnet or SNMP, the unit
must first be properly installed and powered up.
Configuring for Telnet
When the Cisco ONS 15501's Ethernet port is connected to other Ethernet switches for network
management purposes, it is recommended that either end of the Ethernet port NOT be configured in
auto-negotiation mode, and that both ends of the Ethernet connection be configured in either 10 Mbps
or 100 Mbps, half or full duplex mode.
Note The 15501 default Ethernet boot mode is half-duplex 10 Mbps.
For additional information, please refer to the ethmode command.
To configure the Cisco ONS 15501 for Telnet, follow these steps:
Step 1 Connect the Cisco ONS 15501 to an Ethernet LAN using a standard RJ-45 cable.
Step 2 Make sure that the system network is properly set up using ping to the IP address of the system.
Step 3 Enter telnet target-ip-address to log in remotely to the Cisco ONS 15501.
