All the ERM04 chassis power supplies are hot swappable and modular, installing two into a chassis provides redundancy should a

single power supply fail. A fully loaded chassis can run continuously with only one power module fitted into the chassis.

Power Redundancy

To further increase system reliability, the ERM04 chassis is fitted with two hot swappable fan modules. Both fan modules can be

easily removed from the rear of the chassis, without interruption to the operation of the line cards. A fully loaded chassis can run

continuously with only one fan module fitted into the chassis.

Cooling Fan

The ERM04 features cascadeable management which allows managing a stack (up to 10 chassis) from a single IP address. Chassis

are interconnected with standard UTP cables that carry control signals. Each chassis has its own ID, starting with the master chassis

ID0 and cascading up to ID9.

Chassis cascade

Network Management

The ERM04 chassis has been designed as a Multi-serivce platform. This allows network administrators to deploy the chassis in a wide

range of networks. Technologies supported by the chassis included Fast/Gigabit Ethernet, E1/T1, V35/X21/RS530, Serial RS485/422,

Voice FXO/FXS, Repeater, Fiber Multiplexer, E1 Inverse Multiplexer and 10G, 2.7G Transponder.

Protocol Supported

The ERM04 chassis provides an NMC (Network Management Controller) card which must be installed into the first slot of chassis. The

NMC card allows a network administrator with the ability to configure and monitor the status of the blades.

Management can be achieved locally over RS232, or over the network by Telnet, Web or SNMP If the blades support Ethernet in

the First Mile (IEEE 802.3ah), then the management module can also configure and monitor the status of a remote blade.
