50 I/O Circuit Board Ethernet Circuit Board • Cache DIMM memory The I/O circuit board provides the interface between the enclosure and a host, as well as general support functions. The I/O circuit board provides the following: • Connections to the host • Connections to the enclosure • Dual switching power supply for +3.3 V and +2.5 V • Hot pluggability for the controller • Support for the BBU The I/O circuit board has two SFF optical transceivers supporting shortwave multimode fibre on the host side and a 90-pin controlled impedance (50 Ohm) connector on the device side. An HSSDC connector with repeaters on the expansion loop provides for a copper connection between one of the device channels and an expansion module. Port bypass circuitry on the I/O circuit board enables quadplex operation on a second host loop. The I/O board has seven LEDs to indicate subsystem status. The ethernet circuit board provides a 10BASE-T/100BASETX LAN connection for out of band service for the RAID controller. Features of the ethernet circuit board include: • PCI ethernet controller chip • Enhanced scatter-gather bus mastering • Operation in either full duplex or half-duplex mode • Auto-negotiation for speed, duplex, and flow control • RJ45 ethernet connector with integral activity and link status LEDs The PCI ethernet controller is a fully integrated 10BASE-T/ 100BASE-TX controller consisting of both the media access controller (MAC) and physical layer (PHY) in one package.

Cache DIMM memory
I/O Circuit Board
The I/O circuit board provides the interface between the
enclosure and a host, as well as general support functions.
The I/O circuit board provides the following:
•
Connections to the host
•
Connections to the enclosure
•
Dual switching power supply for +3.3 V and +2.5 V
•
Hot pluggability for the controller
•
Support for the BBU
The I/O circuit board has two SFF optical transceivers
supporting shortwave multimode fibre on the host side and a
90-pin controlled impedance (50 Ohm) connector on the
device side. An HSSDC connector with repeaters on the
expansion loop provides for a copper connection between
one of the device channels and an expansion module. Port
bypass circuitry on the I/O circuit board enables quadplex
operation on a second host loop. The I/O board has seven
LEDs to indicate subsystem status.
Ethernet Circuit
Board
The ethernet circuit board provides a 10BASE-T/100BASE-
TX LAN connection for out of band service for the RAID
controller. Features of the ethernet circuit board include:
•
PCI ethernet controller chip
•
Enhanced scatter-gather bus mastering
•
Operation in either full duplex or half-duplex mode
•
Auto-negotiation for speed, duplex, and flow control
•
RJ45 ethernet connector with integral activity and link status
LEDs
The PCI ethernet controller is a fully integrated 10BASE-T/
100BASE-TX controller consisting of both the media access
controller (MAC) and physical layer (PHY) in one package.
