Downloading to a Redundant Wide Bank 28 DS3
This procedure applies when you are using TFTP to download, invoked either through the RS-232
port or by Telnet session through the Ethernet port. Connect a PC or terminal as described in
Connecting to the Management Port on page 6-3.
Figure 6-4 shows the state of the Wide Bank before any action is taken to initiate a TFTP download.
Controller A is in control and is handling all traffic.
NOTE: Make sure there are no existing error or alarm conditions on the unit before you
proceed. Ensure that revertive is turned off (revertive ds3 off) before initiating any
downloads. A revertive switch while downloading a file will abort a download.
