A.3 Storage temperatures for individual VM600 system components
The storage temperatures for individual VM600 system components are given in Table A-2.
A.4 Temperature derating for the power entry module of a VM600 rack
The AC-input rear panels with mains sockets used by ABE04x racks have a compact filtered
power entry module with an IEC type C14 connector (IEC 60320).
As shown in Figure A-1, this power entry module requires temperature derating when the
VM600 rack operates in environments with temperatures greater than 50°C (122°F).
Basically, the power entry module (and VM600 rack) can operate at 100% power for
temperatures up to 50°C (122°F), but for temperatures greater than 50°C (122°F) it must be
derated linearly to 50% power at 70°C (158°F).

Notes
In 2015, the CPUM card was updated to use a new CPU module (PC/104) that supports two Ethernet interfaces by default.
However, this change resulted in different temperature specifications for the CPUM/IOCN card pair.
1. Earlier versions of the CPUM card (PNR 200-595-075-HHh or earlier) fitted with the MSM586EN or equivalent
CPU module have a storage temperature range of −25 to 85°C.
2. Later versions of the CPUM card (PNR 200-595-076-HHh or later) fitted with the PFM-541I or equivalent
CPU module have a storage temperature range of −25 to 80°C.
