TCP/IP settings

The TCP/IP option on the left navigation menu, selected by default when you choose Network on the
top menu bar, displays the current TCP/IP settings of the cooling unit (the IP address, subnet mask, and
default gateway) and the MAC address.
On the same page, TCP/IP Configuration provides the following options for how the TCP/IP settings
will be configured when the cooling unit turns on, resets, or restarts: Manual, BOOTP, DHCP, and
DHCP & BOOTP.
For information on DHCP and DHCP options, see RFC2131 and RFC2132.
TCP/IP
Setting Description
Manual The IP address, subnet mask, and default gateway must be configured manually. (The
MAC address is not configurable.) Click Next>> and enter the new values.
BOOTP A BOOTP server provides the TCP/IP settings. At 32-second intervals, the cooling unit
requests network assignment from any BOOTP server:
•If it receives a valid response, it starts the network services.
•If it finds a BOOTP server, but the request to that server fails or times out, the cooling
unit stops requesting network settings until it is restarted.
•By default, if previously configured network settings exist, and it receives no valid
response to five requests (the original and four retries), it uses the previously
configured settings so that it remains accessible if a BOOTP server is no longer
available.
Click Next>> to access the BOOTP Configuration page to change the number of retries
or the action to take if all retries fail to find a BOOTP server: 1
•Maximum retries: Enter the number of retries that will occur when no valid response
is received, or zero (0) for an unlimited number of retries.
•If retries fail: Select either Use prior settings (the default) or Stop BOOTP request.
1 The default values for these three settings on the configuration pages generally do not need
to be changed:
• Vendor Class: APC
• Client ID: The MAC address of the cooling unit, which uniquely identifies it on the local
area network (LAN)
• User Class: The name of the application firmware module
