Connecting the small form-factor pluggable
(SFP+) transceivers
The NetBackup appliance requires an SFP Fibre Channel adapter to be plugged
into the Fibre Channel ports if the appliance uses a Fibre Channel plug-in. The
adapter allows usage of optical and copper Fibre Channel cables.
The NetBackup appliance supports Fibre Channel (FC) tape out PCIe add-in cards.
The cards connect to other devices through fiber optic cables.
The fiber optic cables require Small Form-factor Pluggable (SFP+) transceivers.
The diagram shows the SFP (1) and the fiber optic cable which is attached to it (2).
Warning:
The laser beams of an optical interface board or inside an optical fibre
can cause eye damage. Do not look directly into the transceiver or point the
transceiver at another person's eyes.
When connecting optical fibers, note the following:
■
An optical transceiver is electrostatically sensitive and it should be placed in an
ESD-preventive and dust-proof environment for transportation, storage, and
use.
■
Optical fibers and optical transceivers not in use must be protected with dust
caps seated properly on the connectors. If the optical transceiver is contaminated,
carefully clean the optical interface.
■
Keep the surface of all optical connectors clean and free from scratches.
■
Do not squeeze, distort, fold, or repair an optical fiber.
■
Do not bend the optical fiber into a circle with a radius less than 5 cm. Otherwise,
the optical fiber may be damaged, which reduces the system performance or
causes data loss.
To connect optical fibers
1
Put on proper ESD-preventive gloves or wrist straps.
2
Take the cap of the optical transceiver out of the interface of the tape out card
(two-port 8 Gb FC HBA).
