How does one check the IP address, subnet mask, and default gateway of the
XLi?
Log on to the XLi and enter the following command:
> F100 IC
F100 IP:192.168.47.156 SM:255.255.255.0 G:192.168.47.1
Is the null modem cable necessary? What if I’m upgrading a XLi remotely?
The null-modem cable is optional. If you decide to Telnet to the XLi over TCP/IP network, you don’t need
the null modem cable.
I’m using a null modem cable to connect to the XLi from my laptop and the
XLi keeps rebooting?
An ungrounded voltage level on one of the pins in the null modem cable causes the unit to reset. Use
one of the following work-arounds:
• Connect the laptop to a grounded power supply, if it has one, or ground the laptop’s chassis.
• Do away with the null modem cable. Telnet to the unit over the network.
Use a regular PC instead of the laptop. The PC is connected to a grounded power supply and doesn’t
cause this problem.
