APC ACSC100 User Manual

The cooling unit is shipped with a Network Management Card that enables the cooling unit to be 
managed over a network. Configure the Network Management Card to control this cooling unit through 
a network.

You must configure the following TCP/IP settings before the Network Management Card can operate on 
a network: 

•  IP address of the Network Management Card
•  Subnet mask
•  Default gateway

Caution: Never use the loopback address (127.0.0.1) as the default gateway address 
for the Network Management Card. Doing so will disable the card and will require you 
to reset TCP/IP settings to their defaults using a local serial login.

Note: If a default gateway is unavailable, use the IP address of a computer that is 
located on the same subnet as the Network Management Card and that is usually 
running. The Network Management Card uses the default gateway to test the network 
when traffic is very light. 

See “Watchdog Features” in the “Introduction” of the User’s Guide for more 
information about the watchdog role of the default gateway.

Use one of the following methods to define the basic TCP/IP settings needed by the Network 
Management Card:

•  APC Device IP Configuration Wizard (See “APC Device IP Configuration Wizard” on this page.) 
•  BOOTP or DHCP server (See “BOOTP & DHCP configuration” on page 28.)
•  Networked computer (See “Remote access to the control console” on page 30.)
