System Architecture
Robust physical safety design
The IES-5112 Series supports 1+1 MSC redundancy with a failover switching time of less than 1 second. For both IES-5112/IES-5106 Series, the voltage,
temperature and fan speed sensors are tted into the system. When an abnormal condition is detected, the LED displays and/or the corresponding alarms
will alert the administrators of the situation. In case the system temperature rises over the preset threshold, thermal cuto protection will kick in to shut
down the system automatically.
Sophisticated OAM&P features
The IES-5112/IES-5106 Series provides various management methods: local console port, Web-based conguration, Telnet and SNMP v1/v2/v3-based
EMS (NetAtlas Access). The management functions include Alarm and Status Surveillance, Conguration Management, Performance Management and
Fault Management. Both Series allows multiple administrative accounts with 3-level access privileges. Accounts with the rst-level privilege have full
access to all management objects on the Management Information Base (MIB). Second-level accounts have similar access rights except creating new
administrative accounts, while the third-level accounts are granted read-only access rights to the MIB objects. NetAtlas Access EMS also provides view-
based MIB management that partial MIB objects can be dened and accessed for customization and security reasons. In addition, Cluster Management
enables multiple MSAN administration with single/master IP address, while XML-based northbound interface is equipped to interoperate with external
OSS systems.
