SCSI Controller The server board includes an embedded Adaptec† AIC-7899W SCSI controller providing dual Ultra160 Low Voltage Differential (LVD) SCSI channels. The SCSI bus is terminated on the server board with active terminators that cannot be disabled. The onboard device must always be at one end of the bus. The device at the other end of the cable is terminated with the active terminator on the SCSI cable installed in the system. Network Controller NOTE To ensure EMC product regulation compliance for inta-building lighting surges, the system must only be used with shielded LAN cables that are grounded at both ends. The server board uses two Intel® 82550PM Fast Ethernet Controllers and supports two 10Base-T/100Base-TX network subsystems. On the SERVER BOARD, NIC 1 can be used as both a network interface and server management interface. NIC Connector and Status LEDs The 82550 controller drives LEDs on the network interface connector that indicate link/activity on the LAN and 10- or 100-Mbps operation. The green LED indicates network connection when on and TX/RX activity when blinking. The yellow LED indicates 100-Mbps operation when lit. cc2300 Carrier Grade Server Product Guide 21

SCSI Controller
The server board includes an embedded Adaptec
†
AIC-7899W SCSI controller providing dual
Ultra160 Low Voltage Differential (LVD) SCSI channels.
The SCSI bus is terminated on the server board with active terminators that cannot be disabled.
The onboard device must always be at one end of the bus.
The device at the other end of the cable
is terminated with the active terminator on the SCSI cable installed in the system.
Network Controller
NOTE
To ensure EMC product regulation compliance for inta-building lighting
surges, the system must only be used with shielded LAN cables that are
grounded at both ends.
The server board uses two Intel
®
82550PM Fast Ethernet Controllers and supports two
10Base-T/100Base-TX network subsystems.
On the SERVER BOARD, NIC 1 can be used as both a network interface and server management
interface.
NIC Connector and Status LEDs
The 82550 controller drives LEDs on the network interface connector that indicate link/activity on
the LAN and 10- or 100-Mbps operation.
The green LED indicates network connection when on
and TX/RX activity when blinking.
The yellow LED indicates 100-Mbps operation when lit.
