For medium voltage systems it is common to use two or three autoreclose shots, and, for specific applications, four shots. Using four shots, final dead time can be set for a time long enough to allow thunderstorms to stop before definitive final reclose. This scheme prevents unnecessary lockout caused by consecutive transient faults.
Local access to the CLI
You can use a local computer to connect to the ATS and access the CLI.
1. Select a serial port at the local computer and disable any service that uses that port.
2. Use the communication cable to connect the selected port to the serial port on the front panel of
the ATS.
3. Run a terminal program (such as HyperTerminal®) and configure the selected port for 9600 bps,
8 data bits, no parity, 1 stop bit, and no flow control. Save the changes.
4. Press ENTER up to 3 times to display the User Name prompt.
5. Use apc for the user name and password.
6. See “Configure TCP/IP settings in the CLI” on page 8 to finish the configuration.
Remote access to the CLI
From any computer on the same network as the Rack ATS, you can use ARP and Ping to assign an IP address
to the Rack ATS, and then use Telnet to access the CLI of that Rack ATS and configure the other TCP/IP
settings.
NOTE: After the IP address of the Rack ATS is configured, you can access the Rack ATS using Telnet or SSH,
without first using ARP and Ping. You must enable SSH before using it, so Telnet is required for initial CLI
configuration.
1. Use ARP to define an IP address for the Rack ATS and use the MAC address of the Rack ATS in
the ARP command. For example, to define an IP address of 156.205.14.141 for a Rack ATS that
has a MAC address of 00 c0 b7 63 9f 67, use one of the following commands:
– Windows command format:
arp -s 156.205.14.141 00-c0-b7-63-9f-67
– LINUX command format:
arp -s 156.205.14.141 00:c0:b7:63:9f:67
NOTE: The MAC address can be found on the bottom of the ATS.
2. Use Ping with a size of 113 bytes to assign the IP address defined by the ARP command. For
example:
– Windows command format:
ping 156.205.14.141 -l 113
– LINUX command format:
ping 156.205.14.141 -s 113
3. Use Telnet to access the Rack ATS at its newly assigned IP address. (For example:
telnet 156.205.14.141) Use apc for both user name and password.
(See “Remote access to the CLI” on page 13)
