A complete set of implementation plan for a weak electrical room, template material

ForewordHello, I am Mr. Lin, computer room remodeling plan, computer room refurbishment project should provide a detailed implementation plan, share it today, this can be used as a plan template, simple modification. It can be used in one click. TextChapter 1 Transition instructions

1.1 Transition goals

With this transition, you can implement following functions:

1. A certain project needs to perform a disaster recovery for a bank in order to prevent inconvenience to users in jurisdiction as a result of natural disasters.

2. This migration only performs disaster recovery migration and user hardware setup. The operation is planned to be carried out on May 12, 2020 and to guarantee duty next day (see schedule for specific time).

3. After switching, change network structure according to user's requirements without changing original user's requirements, and apply all security policies of source equipment to new equipment according to user's requirements.

4. This transition only configures original policy, and new user needs are not included in this transition, such as adding two aggregation devices.

1.2 Jump area

The equipment involved in this transition is Sangfor flow control equipment for export, and location of equipment is as follows:

Risk description

Phenomena Analysis

Troubleshooting steps

The aggregator management address is unavailable

Unable to access aggregation device via intranet management PC

1: Check that interface and device address are set correctly.

2: Check main switch port and IP settings.

3: Clear corresponding address entries in ARP address table.

The external network address R1 or R2 is not available

Unable to access external network resources

1. Check cable connection andport mode.

2. Turn off port f0/0 R1 or R2 and restart it.

3.2 Backup scheme

After pre-test time has elapsed, if you are unable to access Internet due to unknown issues, reset connection cable to its original state and roll back.

Chapter 4 Warranty after switching 4.1 Warranty requirements

In order to ensure a smooth switching operation, after switchover of flow control equipment, it is necessary to organize on-site warranty personnel to quickly fix problem as soon as it occurs and reduce business interruption time caused by error.

4.2 Personnel to switch

This switchover takes place in computer room 403, and on night of switchover, security personnel must be in computer room as follows:

To ensure business continuity after switchover, partner will provide an 8-hour on-site visit and a 7*24-hour duty phone next day. If there is a problem during phone call, engineer will arrive on site within 2 hours.

Chapter 5 Optimization Scheme 5.1 Audit Function 5.1.1 Cause Analysis

According to current analysis of project's network access to external resources, there are many access content. To improve efficiency, some access elements are checked.

5.1.2 Optimization settings

According to need for intranet resources, configure devices according to best conditions.
