Replacing the Boot ROM

Replacing the Boot ROM

To upgrade the boot ROM software to a new software image, you must replace the existing boot ROM.

Required Tools and Equipment

You will need the following tools and equipment:

•ROM extraction tool

•One boot ROM

•ESD-preventive wrist strap

Boot ROM Replacement

Caution A PLCC-type boot ROM does not have pins that plug into the socket; instead, the contacts are on the sides of the boot ROM and along the inner sides of the socket. Therefore, you cannot use a small flat-blade screwdriver to remove a PLCC-type boot ROM. Forcing a small screwdriver or other tool between the boot ROM and the sides of the socket to pry out the boot ROM will damage the component, the socket, or both.

To replace the boot ROM, follow these steps:

Step 1 Turn the power switch on the universal gateway off and disconnect site power.

Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

Step 2 Remove all interface cables from the rear panel of the universal gateway.

Step 3 Attach an ESD-preventive wrist strap.

Step 4 Remove the chassis cover. (See the instructions in the section “Removing the Chassis Cover” section on page A1.)

Step 5 Remove the carrier card to access the system board. (See the Cisco AS5350 Universal Gateway Card Installation Guide for instructions on removing the carrier card. This document is available on Cisco.com and the documentation CD-ROM that comes with your universal gateway. See the “Obtaining Documentation” section on page xiii.)

AS5350 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.
