[j-nsp] M320 SW upgrade from Junos 8.4 to 9.2

[Hangu Jeong]

Hi,

Refer to following instructions to upgrade to 9.2,

 In JUNOS Release 8.5, the JUNOS software was extended to use FreeBSD
version 6.1. As a result, the following requirements apply when you upgrade
your routing platform to JUNOS Release 8.5 and later:
 For J-series, M-series, MX-series, and T-series routing platforms, the
minimum requirement for installation media (such as a compact flash disk,
internal flash disk, or PC Card) is 256 MB.
For M-series, MX-series, and T-series routing platforms, you must perform
the upgrade using the jinstall package.

Hangu
