Installing Long Wave SFP+ Modules (16Gbit/s)
The Short wave SFP+ module (16Gbit/s) in the host interface (FC 16Gbit/s) can be replaced with an optional Long
wave SFP+ module (16Gbit/s) for the
ETERNUS AF.
This section explains the installation rules, handling instructions, and replacement procedure for Long wave SFP
+ modules.
Make sure to read "Safety Precautions" before performing replacement of Long wave SFP+ modules.
IMPORTANT
Make sure to turn off the ETERNUS AF before replacing SFP+ modules (16Gbit/s).
Contact your sales representative or maintenance engineer to replace SFP+ modules (16Gbit/s) during
system operation.
Installation Rules for Long Wave SFP+ Modules (16Gbit/s)
One or two Short wave SFP+ modules (16Gbit/s) in a host interface (FC 16Gbit/s) can be replaced with Long wave
SFP+ modules (16Gbit/s).
Short wave SFP+ modules (16Gbit/s) and Long wave SFP+ modules (16Gbit/s) can be mixed in the same host
interface (FC 16Gbit/s).
The SFP+ module configuration must be the same for controller 0 (CM#0) and controller 1 (CM#1).
Installable Long Wave SFP+ Modules (16Gbit/s)
For installable Long wave SFP+ modules (16Gbit/s), refer to "Product List".
SFP+ Module Handling Instructions
● About Condensation
• When moving an SFP+ module from a cold place, such as an un-conditioned
store house in winter, to a warmer places such as an air-conditioned room, the
severe temperature change may result in condensation forming.
To avoid this, allow the packed SFP+ modules sufficient time in the warmer
place (one hour for each 15
°C of temperature difference) to adapt to the new
temperature.
