Protecting Fiber Optic Connections
This section describes the procedures and processes for protecting and cleaning
fiber optic connectors. Fiber optic cabling is used to connect the storage system to
the host or fabric.
Contamination of the fiber optic connectors on either a transceiver or a cable
connector can impede the transmission of data. Therefore, protecting the
connector tips against contamination or damage is imperative. The tips can be
contaminated by touching them, by dust, or by debris. They can be damaged when
dropped. To protect the connectors against contamination or damage, use the dust
covers or dust caps provided by the manufacturer. These covers are removed
during installation, and are installed whenever the transceiver or cables are
disconnected. Cleaning the connectors should remove contamination.
The transceiver dust caps protect the transceivers from contamination. The
transceivers protect the I/O modules from contamination.
Caution: To avoid damage to the connectors, always install the dust
covers or dust caps whenever a transceiver or a fiber cable is
disconnected. Remove,
but do not discard , the dust covers or dust caps
from transceiver or fiber cable connectors only when they are connected.
To minimize the risk of contamination or damage, implement the following
guidelines:
■ Dust Covers
Remove and retain the dust covers and dust caps when installing an I/O
module, a transceiver or a cable. Install the dust covers when disconnecting a
transceiver or cable.
■ When to Clean
Any time you think a connector may be contaminated, or if a connector has
not been protected by a dust cover for an extended period of time, clean the
connector.
■ How to Clean
a. Wipe the connector with a lint-free tissue soaked with 100% isopropyl
alcohol.
b. Wipe the connector with a dry, lint-free tissue.
c. Dry the connector with moisture-free compressed air.
