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 InRow RC/RD/RP (600 mm) User’s Guide TCP/IPSetting Description DHCP At 32-second intervals, the cooling unit requests network assignment from any DHCP server. By default, the number of retries is unlimited. • If the cooling unit receives a valid response, by default it requires the APC cookie from the DHCP server in order to accept the lease and start the network services. • If the cooling unit finds a DHCP server, but the request to that server fails or times out, the cooling unit stops requesting network settings until it is restarted. • If a DHCP server responds with an invalid offer (for example, the offer does not contain the APC Cookie), the cooling unit accepts the lease from that server on the last request of the sequence and then immediately releases that lease. This prevents the DHCP server from reserving the IP address associated with its invalid offer. For more information on what a valid response requires, see “DHCP response options” on page 39. To specify values other than the defaults, click Next>> to access the DHCP Configuration page:1 • Require vendor specific cookie to accept DHCP Address: To disable the requirement that the DHCP server provide the APC cookie, clearclear this check-box. • 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. DHCP and BOOTP The default setting. The cooling unit tries to obtain its TCP/IP settings from a BOOTP server first, and then, if it cannot discover a BOOTP server, from a DHCP server. If it obtains its TCP/IP settings from either server, it switches this setting from the default to BOOTP or DHCP, depending on the type of server that supplied the TCP/IP settings to the cooling unit. Click Next>> to access and configure the same settings that are available on the BOOTP Configuration and DHCP Configuration pages1 and to specify that the DHCP and BOOTP setting be retained after either type of server provides the TCP/IP values. 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 InRow RC/RD/RP (600 mm) User’s Guide DHCP response options Each valid DHCP response contains options that provide the TCP/IP settings that the cooling unit needs to operate on a network, and other information that affects the cooling unit’s operation. Vendor specific information (option 43). The cooling unit uses this option in a DHCP response to determine whether the DHCP response is valid. This option contains up to two APC-specific options in a TAG/LEN/DATA format: the APC Cookie and the Boot Mode Transition. • APC cookie. Tag 1, Len 4, Data “1APC” Option 43 communicates to the cooling unit that a DHCP server is configured to service the cooling unit. By default, this DHCP response option must contain the APC Cookie for the cooling unit to accept the lease. To disable the requirement of an APC cookie, see “DHCP” on page 38. Following, in hexadecimal format, is an example of a Vendor Specific Information option that contains the APC cookie: Option 43 = 0x01 0x04 0x31 0x41 0x50 0x43 • Boot mode transition. Tag 2, Len 1, Data 1/2 This option 43 setting enables or disables Remain in DHCP & BOOTP mode after accepting TCP/IP settings, which, by default, is disabled. – A data value of 1 enables Remain in DHCP & BOOTP mode after accepting TCP/IP settings. Whenever the cooling unit reboots, it will request its network assignment first from a BOOTP server, and then, if necessary, from a DHCP server. – A data value of 2 disables the Remain in DHCP & BOOTP mode after accepting TCP/IP settings. The TCP/IP Configuration setting switches to DHCP when the cooling unit accepts the DHCP response. Whenever the cooling unit reboots, it will request its network assignment from a DHCP server only. Following, in hexadecimal format, is an example of a Vendor Specific Information option that contains the APC cookie and the disable Boot Mode Transition setting: Option 43 = 0x01 0x04 0x31 0x41 0x50 0x43 0x02 0x01 0x01 InRow RC/RD/RP (600 mm) User’s Guide TCP/IP options. The Management Card uses the following options within a valid DHCP response to define its TCP/IP settings. All of these options except the first are described in RFC2132. • IP Address (from the yiaddr field of the DHCP response, described in RFC2131): The IP address that the DHCP server is leasing to the cooling unit. • Subnet Mask (option 1): The Subnet Mask value that the cooling unit needs to operate on the netw...
