[HOW] Migration from DSL to Elite

Senario 1: Setup ELITE connection
Senario 2: Migration from DSL to Elite


Don't worry, and just follow the guide on Senario 1,
WAN IP address most probably is different from DSL, so you may just ignore the WAN IP from DSL,
but it has LAN IP address for their network, please check clearly for what LAN they are using,
and It maybe same with what Singtel gave to you.

Besides that, please check on their current router, is there any NAT translation setup or port forwarding.
If there is, please configure on this new connection router also.

NOTE: Please use back the LAN IP that they are currently using and do test the network.

To change admin password or create more user account to access,

Please check System time and correct it too,

One last time, MOST important,

Please remember to SAVE it after you finish all your configuration,

Otherwise, after you turn off the power, everything will be gone… 

Good Luck for everyone.

[HOW] Setup Elite connection (Singtel, Starhub, M1)

Let's start to access HP MSR-a900. Power up and connect correct cable into the device's LAN port.
Open browser and type http://192.168.1.1/

NOTE: this is the default IP address.

Then web user login page will appear and need to enter username and password to login.
Username: admin
Password: admin

NOTE: don't forget to enter the verification code.

After login successfully, will saw a page as below.
For ADSL configuration, may just go ahead to select on wizard and select basic configuration.

However, this page is guide to configure ELITE connection.
Firstly, have to select WAN Interface Setup under the Interface Setup.

Here is an example:
Singnet given ELITE information as below:-
WAN IP:
10.185.60.109 (Singtel)
10.185.60.110 (Customer)
Subnet Mask: 255.255.255.252

LAN IP:
10.73.203.80 - 10.73.203.95
Subnet Mask: 255.255.255.240

DNS server:
165.21.83.88
165.21.100.88

So after the first step, this is what will display in WAN Interface Setup

Then , please select either Ethernet0/0 or Ethernet0/1 as WAN port, click on the modify icon.

For ADSL, will just select PPP0E as connection mode.
Now, Manual will be the connection mode for this setup.

Next, enter the WAN port information that given by Singnet. Refer to snapshot.

Please take note in:
IP address - WAN IP (Customer)
IP Mask - WAN IP subnet mask
Gateway address - WAN IP (Singtel)
DNS1 and DNS2 - Singtel DNS

Just hit on Apply button after complete filling all the information and there is a window pop out shown that configuration is modifying the router.

After that, the IP address will shown on the WAN Interface table.

Now, we proceed to LAN interface setup by choose LAN Interface Setup in Left panel.

By default, all the 4 LAN ports are in same VLAN1, and we are not going to change anything in VLAN, unless you have 2 network.
So just continue to select VLAN interface setup.

As singtel is given a pool of IP address, so we just choose one from it,
BUT, please don’t take the 1st IP address and Last IP address in the pool as they are network address and broadcast address.
So we select 2nd IP address,

Then click apply, you may lost connection after apply it as you are using LAN port to configure it.
Unless you are using Console cable =)

The DHCP server, we can just ignore if the user didn’t require for it and they may have DHCP server in their network.

Finally, we are done here.

However, we still need to remember the important setting,
NAT, network address translation,
We knows, Singtel is given us Public IP address, but our customer network is using Private IP address,
So we do need NAT to help the network work well.

First, we need to check whether their network has firewall and NAT is managed by other devices,
If no, please do configure NAT in this router as well.
If Yes, we need to disable the NAT in this router!

NAT configuration is at left panel

Please delete whatever you see in the right bottom panel and make sure the network is working well.

Lastly, REMEMBER to save the configuration after complete everything.

[How] combine several parts of a file

When you have a lot of separate file parts, how you gonna combine all these file parts into one? 
Let's check out of this snapshot.

Why to create a new folder for those file parts?
Answer: To make clear view for ourselves, and won't mess up the whole progress.

The steps to combine all the file parts are very easy,
We only need to use "copy /b" command to combine all the file as the snapshot shown.

No matter what time of file extension, even movie, music files, you able to use this command to combine all your file parts rather then use other softwares.
