The LWL fiber-optic GBIC module, which has a blue color-coded SC connector, is
based on long wavelength 1300-nanometer (nm) lasers supporting 1.0625-Gbps link
speeds. This GBIC module supports 9-micron single-mode fiber. You can use cables
up to 10 kilometers (km) in length with a maximum of five splices. The GBIC module
is shipped with a protective plug in place; keep the plug in place if no fiber-optic cable
is connected to the port.
NOTE: The LWL GBIC module uses a Class 1 CD laser, which complies with the 21
CFR, subpart (J) as of the date of manufacture.

The PowerVault 51F has a universal hot-pluggable power supply capable of function-
ing worldwide without voltage jumpers or switches. The power supply autoranges to
accommodate input voltages and line frequencies.
The power supply has a modular design that plugs directly into the enclosure through
the front panel, attaching to an internal connector. The PowerVault 51F also supports a
second redundant hot-pluggable power supply.
The power supply has an integrated on and off switch, input filter, and power indicator.
