5.3 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 an ETERNUS DX.
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.
Make sure to turn off the ETERNUS DX before replacing SFP+ modules (16Gbit/s).
Contact your sales representative or maintenance engineer to replace SFP+ modules (16Gbit/s) during sys-
tem operation.
5.3.1 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).
When two controllers are installed, the SFP+ module configurations for controller 0 (CM#0) and controller 1
(CM#1) must be the same.
5.3.2 Installable Long Wave SFP+ Modules (16Gbit/s)
For installable Long wave SFP+ modules (16Gbit/s), refer to "Product List".
5.3.3 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 tempera-
ture.
