Hardware Acclimation Times; Optical Multimode Cables - Dell EMC VMAX3 Series Site Planning Manual

Hardware acclimation times

Units must acclimate to the operating environment before applying power. This requires the
unpackaged system or component to reside in the operating environment for up to 16 hours in
order to thermally stabilize and prevent condensation.

If there are signs of condensation after the recommended acclimation time has passed, allow
an additional 8 hours to stabilize.
Systems and components must not experience changes in temperature and humidity that are
likely to cause condensation to form on or in that system or component. Do not exceed the
shipping and storage temperature gradient of 45°F/hr (25°C/hr).
OM3 cables are used for SRDF connectivity over: 4, 8, and 10 Gb/s Fibre Channel I/O modules,
10 GbE and 1 GbE I/O modules.
OM4 cables are used for SRDF connectivity over 16 Gb/s Fibre Channel I/O modules.
OM4 cables are used with 16 Gb/s Fibre Channel I/O modules to provide Fibre Channel
connection to switches. Distances of up to 190 m over 8 Gb/s Fibre Channel and 125 m over 16
Gb/s Fibre Channel modules are supported.
