DECbridge 500/600 Series Problem Solving
The I/O panel of the DECbridge 500/600 series units contains the following compo-
nents:
•
Fiber optic connector(s) for the FDDI interface – DAS models have one
FDDI type A and one type B connector; SAS models have one type S con-
nector; the DECbridge 600 has no FDDI connector. Depending on the model,
the connectors may be multimode or single-mode.
•
Connector(s) for the IEEE 802.3/Ethernet AUI interfaces(s). The DECbridge
500 series models have a BNC connector for the ThinWire interface and a
“D” connector for the AUI interface. The DECbridge 600 series models have
three “D” connectors for three separate AUI interfaces.
•
A standard IEC connector for the ac input.
•
Circuit breaker (ac input).
•
LED indicators (located on each of the four logic modules).
•
Configuration switches (located on the AP/AP2 module).
•
An address label showing the 48-bit physical addresses of the ports.
NOTE
The bridge does not have a power ON/OFF switch.
Power is applied to the bridge when the ac power cord is
plugged in. Neither does the bridge have a voltage select
switch because the bridge automatically adjusts to a
voltage range of 88 – 264 Vac.
