Intel® NetStructureTMZT 7102 Chassis Management Module

Hardware Specifications

2.12Memory

The ZT 7102 includes 128 Mbytes of SDRAM on a Small Outline Dual Inline Memory Module (SODIMM). The SODIMM used is 16 Mbits x 72 PC133 unbuffered SDRAM with ECC on a 144-pin module.

2.12.1Removing the SODIMM

The following instructions cover the mechanical aspects of removing the SODIMM from a ZT 7102.

1.Take the necessary precautions to protect the ZT 7102 and the SODIMM from static discharge.

2.Locate the SODIMM socket. Refer to Table 4, “Connector Assignments” on page 22 for the socket's location.

3.Press outward on the clips at either end of the SODIMM socket (press both clips at the same time) until the module ejects from the slot and tilts upward.

4.Pull the SODIMM away from the socket.

2.12.2Installing Memory

The following instructions cover the mechanical aspects of installing the SODIMM in a ZT 7102.

1.Take the necessary precautions to protect the ZT 7102 and the SODIMM from static discharge.

2.Hold the SODIMM at an angle and push it into the SODIMM socket. Refer to Table 4, “Connector Assignments” on page 22 for the socket's location.

3.Align the notches on the ends of the module with the matching bumps on the latches and gently push the module down until it clicks in place.

2.13Flash

The ZT 7102 uses an on-board 64 Mbyte flash memory device.

2.14Dual Ethernet Controllers

The ZT 7102 uses two Intel® 82559 Fast Ethernet Controllers. The 82559 consists of both the Media Access Controller (MAC) and the physical layer (PHY) interface combined into a single component solution.

The CMM provides an RJ-45 connector on the faceplate to connect to out-of-band 10/100 LAN0. This connector is labeled with the Ethernet icon (refer to “Face Plate” on page 20). Care should be taken not to confuse the RJ-45 Ethernet port with the RJ-45 serial port that is next to it. (Note that the Ethernet port has integrated speed and activity LEDs).

2.15Serial I/O

The ZT 7102 provides an RS-232 compatible RJ-45 serial port connector on the faceplate. Serial port signals are also available for rear panel access.
