2. Verify the hot input wires (black) connect to negative terminal lugs.
3. Verify the neutral-return input wires (white) connect to positive terminal lugs.
Connect a digital volt meter to each branch in turn and verify:
■
DVM ground probe-to-system ground and red probe to + (positive) terminals
indicates 0 VDC.
■
DVM ground probe-to-system ground and - (negative) terminals indicates -48

1.7 Connecting Consoles to the System
Controller

The system controller (SC) is responsible for providing the Lights-Out Management
(LOM) functions, which include power on sequencing, sequencing module power-on
self-tests (POST), environmental monitoring, fault indication and alarms.
The LOM command line interface and the Solaris/OpenBoot™ PROM console are
accessed by connecting an administrative console to either serial port A or the
10/100 LOM Ethernet port. The administrative console can be any external input
device (laptop computer or workstation) connected to either of these ports.
Serial port A is used to connect directly to an ASCII terminal or a network terminal
server (NTS) using a command line interface. This port is used for the initial
administrative console. It is used to modify the default system controller settings
(usually so that the 10/100 LOM Ethernet port can be used as an administrative
console). The configuration of Serial port A cannot be changed.
The 10/100 LOM Ethernet port is used to connect the system controller to the
network. This port is preconfigured as follows:
■
System controller configured to be on a network
■
System controller Ethernet configured for dynamic host configuration protocol
(DHCP).
■
No pre-configured system controller Ethernet IP address, Gateway, DNS domain,
DNS servers
