99InRoom Controller - Operating Instructions

2. When the Network Management Card reboots, the BOOTP server provides it with the TCP/IP settings.

– If you speciﬁed a bootup ﬁle name, the Network Management Card attempts to transfer that ﬁle

from the BOOTP server using TFTP or FTP. The Network Management Card assumes all settings

speciﬁed in the bootup ﬁle.

– If you did not specify a bootup ﬁle name, the Network Management Card can be conﬁgured remo

tely by using the control console or the Web interface (user name and password are both apc, by

default).

To create the bootup ﬁle, see your BOOTP server documentation.

DHCP. You can use an RFC2131/RFC2132-compliant DHCP server to conﬁgure the TCP/IP settings for the Net-

work Management Card.

This section brieﬂy summarizes the Network Management Card communication with a DHCP server.

For more detail about how a DHCP server is used to conﬁgure the network settings for a Network Ma

nagement Card, see “DHCP Conﬁguration” in the InRoom Precision Air Conditioner User’s Guide.

1. A Network Management Card sends out a DHCP request that uses the following to identify itself:

– A Vendor Class Identiﬁer (APC by default)

– A Client Identiﬁer (by default, the MAC address value of the Network Management Card)

– A User Class Identiﬁer (by default, the identiﬁcation of the application ﬁrmware of the Network Ma

nagement Card)

2. A properly conﬁgured DHCP server responds with a DHCP offer that includes all of the settings that

the Network Management Card needs for network communication. The DHCP offer also includes the

Vendor Speciﬁc Information option (DHCP option 43). By default, the Network Management Card will

ignore DHCP offers that do not encapsulate the APC cookie in the Vendor Speciﬁc Information option

using the following hexadecimal format:

Option 43 = 01 04 31 41 50 43

where

– the ﬁrst byte (

01) is the code

– the second byte (

04) is the length

– the remaining bytes (

31 41 50 43) are the APC cookie

See your DHCP server documentation to add code to the Vendor Speciﬁc Information option.

To change the control console DHCP Cookie Is setting, use the Advanced option in the TCP/IP

menu. See “Remote access to the control console” on page 100.

To change the Web interface setting Require vendor speciﬁc cookie to accept DHCP Address

which is enabled by default, ﬁrst choose DHCP under the TCP/IP Conﬁguration heading by

selecting the Administration tab, the Network option on the top menu bar, and TCP/IP on the

left navigation menu. To disable the APC cookie requirement, click Next to access the DHCP

Conﬁguration page, and unmark the checkbox „Require vendor speciﬁc cookie to accept

DHCP Address.“
