Card P/N
Config. Dwg.
Diagnostics:
Top and side views of the 907-GEM-R multiplexer motherboard are shown in Figure 3-19. The backplane
PC/104 connector allows stacking of other 907 expansion cards. The 907-GEM card receives +5 VDC power
through a standard two-pin Molex power connector. The power input has overvoltage and reverse polarity
protection. The 907-GEM card can also receive power via the PC/104 connector from other cards when used
in a Model 907 stack. Typical current draw is 1.5 A from a +5 VDC power supply.
The 907-GEM has an array of diagnostic LEDs for Power, Optical Link Ready, Optical Link Error, Port Errors
and Port Tx/Rx Activity. The power LED is green when the input power voltage is within an acceptable range.
When the SFP transceiver is receiving sufficient optical power, the Link Ready LED is green; otherwise, the
Optical Link Error LED is red. The Port Error LEDs are red when the copper port is receiving packets that
cause the input buffers to overflow. Port Tx Activity LEDs are green when packets are being transmitted from
the 907-GEM card and Port Rx Activity LEDs are green when packets are being received into the 907-GEM
card. Also, the quad RJ-45 jack of the 907-GEM card has LEDs to indicate the link status of each copper port;
the orange LED indicates 10 Mbps, the yellow LED indicates 100 Mbps and the green LED indicates
1000 Mbps.
The optical configuration of the card, and any other special options, are designated by the –XX suffix of the
card part number. Refer to the configuration drawing for more details.
