Bus Power
Bus-powered with FireWire 800, the PortaGig 62 also includes USB and eSATA ports for optimum compatibility, allowing you to
easily work on the road with a reliable RAID. Although eSATA is not a bus-powered interface, you can use the eSATA connection for
fast data transfer (up to 177MB/s) while simultaneously using the FireWire 800 connection to power the drive. An external power
supply is included with the PortaGig 62 if bus power is not available or is insucient.
PortaGig 62 can be run successfully using FireWire bus power supplied by many notebook computers, however Glyph can’t guar-
antee compatibility with all notebooks due to diering bus power specs. If you want to guarantee PortaGig 62 will work, use the
included DC supply.
Glyph Manager Software
Glyph Manager software constantly monitors the drive and enclosure health, notifying you if there is a problem, allowing you to
work on the road easily and reliably. Connected by FireWire 800, USB or eSATA, it reports the drive’s health and temperature as a
background task. It is not necessary to install Glyph Manager for the PortaGig 62 to function, but is very convenient in trouble-
shooting, notifying you if your drive needs attention.
Front panel LED
The PortaGig 62 front panel has a bi-color LED. The LED will display solid blue when power is on. The LED will ash blue when
there is disk activity. The LED will ash or display a solid red color when error conditions exits with the drive or enclosure. Any
error that results in the system state “Halted” generates a solid red LED on the front panel of the drive. All other errors result in
the blinking red LED. All errors will animate the Glyph ball in the dock under OS X or generate an error balloon under Windows, if
Glyph Manager software is installed.
About eSATA
• eSATA is an external interface technology that grew from the internal SATA I interface.
• The PortaGig 62 eSATA port supports speeds up to 3 Gb/sec (300 MB/sec), much faster than FireWire 400 or FireWire 800.
• Shielded eSATA cables up to 2 meters in length are available.
• eSATA cables are dierent than SATA I cables, they are shielded and cannot be used with internal SATA I connectors.
• eSATA uses a “point-to-point” connection, therefore each eSATA drive needs to be connected to its own eSATA port.
• Most computers do not have built-in eSATA, so you’ll need a PCI card to connect your drive with eSATA. Glyph sells various eSATA
cards.
About FireWire
FireWire is an implementation of the IEEE 1394 serial bus standard. It not only supports automatic conguration (“plug and play”)
and hot-swapping of devices, it’s fast, and best of all it’s reliable for audio/video as well as for computer peripherals. FireWire
supports peripherals in a tree-like structure, and it allows peer-to-peer device communication—e.g. between a scanner and a
printer—to take place, without using system memory or the CPU. With FireWire you can hook up to 63 devices to the same bus,
with cable lengths of up to 4.5 meters (14 feet) including internal cabling, allowed between devices. Its cable is convenient and
can also carry power. This allows low-consumption devices to operate without a separate power cord, by using power supplied by
other devices on the bus.
About FireWire 800
• FireWire 800 supports speeds up to 800 Mb/sec, twice as fast as FireWire 400.
• If your computer does not have built-in FireWire 800, you’ll need a PCI card to achieve a true FireWire 800 connection.
• Most 800 ports are Bi-Lingual, which means they speak both FireWire 400 and FireWire 800.
• If you connect a 400 device to an 800 device, you will be running at 400 speed maximum.
• FireWire is forward-compatible and back-compatible.
• Beta cables are used to connect 800 devices to 800 devices.
• Bi-Lingual cables are available to connect 400 devices to 800 devices.
• Bi-Lingual cables have a 9-pin Bi-Lingual connector at one end and a 4-pin or 6-pin FireWire 400 connector at the other end
