Solution
1. Check if the LAN cable is connected
to the LAN port.
2. Make sure that the IP address of
both the remote and local/central
servers are on the same subnet.
(Refer to chapter 2 for details.)
Try "ping xx.xx.xx.xx" (remote
server ip) on local/central server
and make sure remote server could
reply the ping request.
3. Check if the IP source is set to
[DHCP]. When set to [DHCP], you'll
not be able to configure the IP
address.
The maximum SEL number is 900 events.
Refer to section 4.4.9 to check if the time
zone is set up correctly.
Ask MIS to add the following port
numbers in Firewall:
5123 (virtual floppy) (TCP)
5120 (virtual CDROM) (TCP)
623 (IPMI) (TCP & UDP)
80 (HTTP) (TCP)
7578 (iKVM) (TCP)
443 (HTTPs) (TCP)
