OSD2254P OPERATION
When using the OSD2254P for the first time, check that the unit is in good condition with no visible
damage.
Upon power up check that the indicators illuminate accordingly on power up (see Table 4).

CONNECTIONS
For RJ45 connection use Category 5 (CAT5) or higher. Length should be no more than 100 meters.
For singlemode fiber connections, fiber used must be 9/125
µ
m singlemode fiber.
For multimode fiber connections, fiber used must be 50/125
µ
m or 62/125
µ
m multimode fiber.
Plug in the appropriate connectors for system configuration;
–
RJ45 cable to fixed copper ports (port 1 and 2) and copper SFP modules
–
LC or SC fiber cable to fiber SFP modules.
Redundant Ring Operation
The OSD2254P connected in a redundant ring topology providing maximum reliability on critical
networks. In the event of device or fiber failure the data path will automatically switch to a secondary
path in less than 2ms per node to maintain ring network integrity.
