Table 2-3 describes the technical specifications for the 2XP PCI card.

Table 2-3: 2XP PCI Card Specifications

Feature

Specifications

Notes

2XP PCI card

64-bit PCI-X and PCI

protocols

Can be used in any 3.3V PCI

slot.

Bus speed

66-133 MHz

Capable of peak PCI

date rates at the limits

of the PCI-X or PCI buses

(1067MB for 64-bit, 133MHz

PCI-X and 533MB for 64-bit

at 66 MHz).

Local memory

2 MB

Memory bandwidth

2664 MB/s

Processor

333 MHz RISC

LANai 2XP.

Fiber port physical

LC-type optical connector,

50/125 multimode fiber pair

Class I Laser Product (no

hazard).

Fiber port data rate

2.0+2.0 Gb/s data rate,

2.5+2.5 GBaud signaling,

8b-10/b encoded

The standard firmware

distributes packets

adaptively across the

two ports, such that the two

ports act as a single 4.0+4.0

Gb/s data-rate port.

EEPROM

512 KB

Includes the PCI-

configuration-space data,

such as serial number,

MAC address, and product

code. The EEPROM can be

reprogrammed by the 2XP.

Table 2-4 describes the physical and environmental characteristics of the 2XP

PCI card.

Table 2-4: 2XP PCI Card Physical Characteristics

Characteristic

Specifications

Dimensions (excluding faceplate)

6.4 cm high, 16.4 cm long, 2.2 cm thick

(low-profile PCI short card)

Mass

82g (including the faceplate)

Power requirement

3.3V from the PCI bus, 2.0A (6.6W) maximum

0C to 50C up to 10,000 foot altitude

Environmental, operating

Relative humidity 15% to 80% @ 50C

-40C to 70C

Environmental, nonoperating

Relative humidity 90% @ 65C

2.4 Single-port 2XP PCI

The single-port 2XP PCI NIC (Figure 2-4) is the Myricom Rev. F card. It supports

one X-port interface and one PCI-X interface. These NICS must use the Myricom

GM-2 or Myrinet Express (MX) software.

Other than the difference in the number of ports, the Rev. F card has the same

specifications as the Rev. E card.
