CRP-C0266-01

(4) Network Unit

The Network Unit is an interface board for connection to an Ethernet

(100BASE-TX/10BASE-T) network.

(5) Controller Board

The controller board contains processors, RAM, NVRAM, Ic Key and FlashROM. The Ic Key

is a security chip that generates random numbers and encryption keys, and detects any

tampering with the MFP control software.

MFP control software is installed in the FlashROM that is on this Controller Board. MFP

control software consists of the following software such as System/Copy, Network Support,

Scanner, Printer, Fax, Web Support, Web Uapl, and Network Doc Box.

(6) Ic Ctlr

Ic Ctlr is a security chip that encrypts information to be stored on the HDD, and decrypts

information to be read from the HDD.

(7) HDD

HDD is a hard disk drive where document data (non-Scanner Function), document data (only

for the Scanner Function), print data, fax reception data, user information for identification

and authentication, and audit logs are recorded. The area that stores document data

(non-Scanner Function), document data (only for Scanner Function), print data, and fax

reception data is called D-BOX.

(8) USB Port

The USB port is used to connect a client computer to the TOE, print or fax from the client

computer.

(9) SD Card Slot

SD card slot is a slot for maintenance that customer engineers use for SD cards. It is on the

side of the TOE and is usually covered by a cover with a screw. The customer engineers

remove this cover and insert the SD card for maintenance. The slot is used for the activation

of the Stored Data Protection Function and the initial settings to encrypt the HDD when the

TOE is installed. No maintenance based on this certification is assumed, so this interface is

used only for the installation of the TOE.

5.2 IT Environment

The TOE is connected to the internal network and performs communication with server

computers such as FTP server, SMB server, SMTP server, and client computers. Then the

TOE performs the communication with client computers connected by USB and the fax device

of the destination fax connected via telephone lines.

The TOE performs the document data transmission into server computers such as FTP server,

SMB server, and SMTP server that are connected via the internal network.

Client computers that are connected to the TOE via the internal network or USB use the

TOE through the printer driver and Web browser. The client computers send and receive

document data. They also operate some Management Functions and check the TOE

performance through the Web browser.
