The height of MIM cards may be one U (44.45 mm or 1.75 in.) or half a U. Slot 5 and slot 6 on the MSR
30-20, MSR 30-40, or MSR 30-60 are both half a U high. The two slots together can accommodate only
one 1-U-high MIM card.

z Boot ROM stores bootstrap.
z The memory is used to store the communication data between the system and the CPU when the
system is running.
z The CF card is used to store the software system and configuration file. The CF card LED blinks
when the system is reading/writing data from/to the CF card. In this case, do not remove the CF
card, otherwise hardware and software damage may occur.
