EonStor F16F-R/S4031 Installation and Hardware Reference Manual
CAUTION!
1. All fiber optical cables are sensitive and must be handled with
care. To prevent interference within a rack system, the cable
routing paths must be carefully planned and the cables must not
be bent.
2. If it becomes necessary to apply 2Gb/s Fibre Channel devices in
your storage network, e.g., 2G HBAs, you must manually
configure your host link speed to 2Gb/s.
3. The “Auto-negotiation” mode is not supported.
4. Most 2Gb/s devices are supported. Please refer to the latest
Interoperability Test Report for more information.

Topology and Configuration
Considerations
Basic Configuration Rules
The following are some basic rules that should be followed.
When cabling, pay attention to signal quality and avoid electronic noise
from adjacent interfaces.
The drives included in the same logical configuration should have the
same capacity, but it is preferred that all disk drives within the
subsystem have the same capacity.
If Spare drive is preferred for automatic rebuild in a multi-enclosure
environment, use Enclosure Spare instead of Global Spare
configuration. Please refer to your firmware operation manual.
The certified transceiver and optical cables comply with laser eye safety
Class 1 standard. When handling optical cables, pay attention to laser
eye protection measures. Though unseen, laser light can still inflict
damage to your eyes.
It is not recommended to change the cable length or tune the cables
unless you have adequate equipment and received proper training.
Tuning the cables require a complete set of equipment including
combination strip tool, sapphire scribe tool, die set, heat cure oven, etc.
Particles or poorly polished fiber can cause immanent problems.
