We are also planning to attach a lto4 library with this.
So ,does this library can read lto2 tapes if we need to restore something.

Can I use LTO 4 media in my LTO 1, 2 and 3 drives?
No. LTO1, 2 and 3 drives are unable to read or recognize LTO4 media. LTO4 media can only be used in LTO4 drives.

Can I use LTO 1, 2 and 3 media in my LTO 4 drive?
According to drive manufacturer, LTO 4 format is backwards compatible with LTO 2 and 3 data cartridges only. This means LTO 2 and LTO 3 media may be both read in an LTO 4 drive, but backwards write compatibility is limited to LTO3 media.

LTO 4 WORM cartridge:
LTO 4 WORM cartridge can only be used in an LTO4 drive equipped with WORM functionality.

Google would have answered this fairly quickly for you.
