ZyXEL ALC1248G-53 91-004-476001B Manual Do Utilizador

The IES-6000 supports 1+1 MSC redundancy with a failover switch time less than 1 second. In addition, voltage, temperature and FAN speed sensors are 

fitted into the system. When an abnormal condition is detected, the LED displays and/or the corresponding alarms will alert administrators of the situation. 

In case the system temperature rises over the preset threshold, thermal cutoff protection will kick in to shut down the system automatically.

The IES-6000 provides various management methods: local console port, Web-based configuration, Telnet and SNMP v1/v2/v3-based EMS (NetAtlas Access 

EMS). The management functions include Alarm and Status Surveillance, Configuration management, Performance management and Fault management. 

The IES-6000 allows multiple administrative accounts with 3-level access privileges. Accounts with the first-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 defined and accessed for customization and security reasons. In addition, Cluster Management enables multiple DSLAM administration 

with single/master IP address, XML-based northbound interface is equipped to interoperate with external OSS systems.
