• The IEC Class 1 laser is safety compliant under normal
operating conditions. The Class 1 rating is due to an integrated
automatic shutdown circuit that disables the laser when it
detects transmitter failures. The FITS rating of the internal
shutdown circuit is less than 500 FITS.
• The FDA Class 1 laser is safety FDA compliant.
• The product is shipped with a removable process plug
covering the optical interface.
• A mechanical cover engages when the fiber cable is removed
from the optical interface. The cover provides dust protection
in the event of the optical interface being disconnected, and
additional protection to the human eye.
SNMP
The OSU 300's embedded SNMP feature allows unit access and
control by a network manager through either the auxiliary (AUX)
control port or the 10BaseT local area network (LAN) port. The
OSU 300 supports the MIB-II standard, RFC 1213 and 1407, and the
ADTRAN Enterprise Specific MIB.
The term SNMP broadly refers to the message protocols used to
exchange information between the network management system
(NMS) and the managed devices, as well as to the structure of
device management databases. SNMP has three basic components:
Network Manager, Agent, and MIB.
Network Manager
Control programs that collect, control, and present data pertinent to
the operation of the network devices. These programs reside on a
network management station.
Agent
Control program that resides in every network device. This
program responds to queries and commands from the network
manager, returns requested information or invokes configuration
changes initiated by the manager, and sends unsolicited traps to the
manager.
