Power and Warning LEDs

 

 

 

 

 

PWR (dial shelf controller power)

Green

Lights when power is ON.

 

 

 

MBUS (system MBus power)

Green

Lights when the dial shelf controller card is

 

 

 

supplying +5 VDC to the system MBus.

 

 

 

MAJ (major alarm)

Yellow

Lights to indicate a major1 alarm condition.

MIN (minor alarm)

Yellow

Lights to indicate a minor2 alarm condition.

ACO (alarm cutoff)

Yellow

Lights when the alarm cutoff button has been

 

 

 

pressed during a major or minor alarm. Turns off

 

 

 

when the original alarm clears or any new alarm

 

 

 

occurs.

 

 

 

HIST (history clear)

Yellow

Lights when software recognizes a major or minor

 

 

 

alarm situation. LED powers off when the Clear

 

 

 

Alarm button is pressed and no alarm condition

 

 

 

remains.

 

 

 

Clock and Status LEDs

 

 

 

 

 

 

CLK (clock)

 

Green

Lights to identify the dial shelf controller card

 

 

 

active clock; active clock is independent from

 

 

 

master dial shelf controller card designation.

 

 

 

MAST (master)

Green

Lights to indicate the system software recognizes

 

 

 

the dial shelf controller card is in master mode.

 

 

 

 

Slot 0

 

Green

Lights when PCMCIA slot 0 is in use.

 

 

 

 

Slot 1

 

Green

Lights when PCMCIA slot 1 is in use.

 

 

 

DSI (dial shelf interconnect)

Green

Lights to indicate a working connection between

 

 

 

the dial shelf and router shelf.

 

 

 

10BaseT (Ethernet link)

Green

Lights to indicate a working data transfer link

 

 

 

connection between the access server and the

 

 

 

system controller.

 

 

 

Liquid Crystal Displays

 

 

 

 

 

LCDs (upper and lower)

AS5800 specifications

Cisco Systems has long been a leader in the networking and telecommunications field, and its AS5800 series of routers exemplify this tradition. The AS5800, along with the AS5850, AS5350, AS5400, and AS5300, provides robust solutions for service providers and enterprise-level networking applications. Each of these models has distinct features and characteristics that cater to the evolving demands of internet traffic and data processing.

The Cisco AS5800 is designed for high-capacity routing and optimized for broadband services. It supports a wide range of services, including voice, data, and video applications, making it a versatile option for service providers looking to deliver integrated solutions. It is equipped with advanced quality of service (QoS) features that ensure bandwidth is allocated effectively, holding strong even under heavy traffic conditions.

In comparison, the AS5850 offers superior processing capabilities and is typically utilized in larger-scale implementations. This model supports high-density interfaces, allowing numerous connections without compromising performance. Its architecture includes enhanced MPLS (Multiprotocol Label Switching) support, enabling more efficient traffic management and better utilization of network resources.

The AS5350 is known for its scalability and energy efficiency, ideal for voice-over-IP (VoIP) and media gateway applications. It supports various telephony features, such as protocol interworking and transcoding, making it a preferred choice for organizations focusing on digital voice technologies. The AS5300, while slightly older, continues to be a valuable asset for less demanding networks, offering reliable performance with VoIP capabilities and basic data applications.

The AS5400 bridges the gap between high-performance routing and operational efficiency. It incorporates Cisco's proprietary technologies to ensure seamless connectivity and robust failover systems. This model is highly regarded for its security features, protecting network integrity and providing peace of mind for businesses relying on sensitive data transfer.

Overall, Cisco’s AS5800 series showcases a progressive evolution of routing capabilities with enhanced features tailored for resilience, scalability, and performance. These routers not only address the technical needs of modern networks but also strategically position organizations for future growth in an increasingly digital world. Each model, with its unique attributes, continues to support the varied demands of global communication infrastructures.
