NOTE
Incorrect wiring will result in chassis malfunction.
The iMediaChassis/3 is compliant with Isolated Grounding Plane practices. The
POSITIVE and NEGATIVE terminals are isolated from chassis ground and must
have a ground reference at the power-sourcing equipment.
POW ER SUPPLY MODULES
Power supply modules in all models of the iMediaChassis/3 are fixed, and not
end-user replaceable.
FANS
The iMediaChassis/3 includes temperature-triggered fans. When the temperature
inside the chassis reaches 45° C, the two fans activate to cool the chassis. Fans
are not end-user replaceable.
Installing Management and Application Modules
SNMP Management Modules include two twisted pair ports, one for management
and one reserved for future use. The Management Module also features a DB-9
serial port, and supports SNMP V1/V2c.
