M3-M Myrinet-2000 Switch Monitoring Line Card |
These specifications concentrate on the physical characteristics of this product. Please see this Guide to Myrinet-2000 Switches and Switch Networks for information about the installation and the principles of operation of this family of products.
This monitoring line card may be used only in the top line-card slot of the M3-E16, M3-E32, M3-E64, and M3-E128 enclosures.
Ethernet ports (2): Dual-redundant 10-Base Ethernet ports. The Ethernet MAC address is shown on a label on the front panel. Each Ethernet port has a green LED: Off: not connected to an active port; On: connected; Blinking: traffic.
Main Microcontroller: A Power-PC microcontroller with RAM and flash memory communicates via individual serial links with small microcontrollers on port line cards, associated with XBar16s on the backplane, on a fan-monitoring board, and on the monitoring line card itself. The standard firmware runs under VxWorks, and provides SNMP as well as a simple web server.
Small-Microcontroller functions: Self-test, board identification, voltage monitoring, and temperature monitoring (upstream & downstream in the air flow). All status information is reported on demand through the serial link to the main microcontroller. The µC will shut off the line-card power on over-temperature or other fault conditions. The µC controls a Status LED on the front panel: Off: not operating; Green: operating. Yellow: fault.
Power requirements: Dual +12V input power @ 0.4A (4.8W) maximum. Power-indicator LEDs for both +12V sources. This line card is hot-swappable.
Physical characteristics: 9U-220mm card per IEEE 1101.10, with specialized connectorization. Detail dimensional specifications are given here. Weight 20oz (570g).
Regulatory Approvals: When properly installed in a Myricom M3-E16, M3-E32, M3-E64, or M3-E128 enclosure, the line card is fully compliant with EN55024 (1998), EN55022 Class A (1998), VCCI Class A (May 1999), FCC Part 15 Subpart B Class A, CISPR 22/85 Class A, ICES-003 Class A (ANSI C63.4 1992), and AS/NZS 3548 Class A (w/A1 & A2 1997).
