Date Code 20080110 SEL-300 Series Relays Firmware Upgrade Instructions B-21
SEL-387E Instruction Manual
Required Equipment
Gather the following equipment before starting this firmware upgrade:
• Personal computer
• FTP client software (e.g., Microsoft Internet Explorer)
• Disk containing the communications card firmware upgrade (.s19) file
• Firmware upgrade instructions (these instructions)
Upgrade Procedure
A. Prepare the Relay
Step 1. If the relay is in use, follow your company practices for removing a relay from
service. Typically, these include changing settings, or disconnecting external voltage
sources or output contact wiring, to disable relay control functions.
Step 2. Apply power to the relay.
Step 3. These instructions assume that the Ethernet port (PORT5) settings are set as follows:
IPADDR = 10.201.0.213
SUBNETM = 255.255.0.0
DEFRTR = 10.201.0.1
ETELNET = Y
TPORTC = 1024
EFTPSERV = Y
FTPUSER = 2AC
B. Establish an FTP Connection
The following instructions use Internet Explorer operating on Microsoft Windows XP as the FTP
client to establish communications between the relay and a personal computer. The instructions
assume both devices are on the same side of any firewalls.
Step 1. Connect an Ethernet communications cable between the relay Ethernet port (PORT 5)
and the computer Ethernet port.
Alternately, connect an Ethernet communications cable from the relay Ethernet port
to an Ethernet network and another cable from the personal computer Ethernet port to
the same Ethernet network.
Step 2. From the computer, open Internet Explorer.
On a personal computer running Windows, you would typically click on Start >
Programs > Internet Explorer.
