Using the GT 062E with Windows 2000 / XP
Older versions of Windows, such as 2000 and XP 32-bit, use Master Boot Record which doesn’t support vol-
umes larger than 2TB. When the total capacity of the RAID is 2TB or higher, you must format the array using
GPT in Windows. GPT format is only supported by Windows XP 64-bit Edition, Windows 2003 Server, Win-
dows Vista, Windows 7, and Mac OS X. GPT format will not work with XP 32-bit or older Windows operating
systems. If you want to use Windows 2000 and/or XP 32-bit, you’ll need to run the GT 062E in RAID 1 mode
because RAID 1 creates a usable volume that is half the total capacity (1.5TB for the 3TB, and 2TB for the
4TB).
GT 062E Ports
The fastest interface on the GT 062E is eSATA and there is one eSATA port on the rear panel. In RAID 0 mode,
the GT 062E can sustain over 200MB/sec (read speed) when connected via eSATA to a fast eSATA card such as
a Sonnet E4P card. FireWire 800 is the next fastest and there are two FW800 ports on the rear panel. Official-
ly, these IEEE 1394b ports run at up to 800Mbits/sec. If using FW800, one of these ports should be connected
to your computer, and the other should be connected to other downstream FireWire devices. It doesn’t mat-
ter which port you connect to the computer, they are functionally identical. If your computer has a FireWire
400 port only, you can use a FW400 to FW800 adapter cable, which is available from Glyph. If your computer
doesn’t have any FireWire ports you can either purchase an eSATA or FireWire adapter card (recommended),
or use the USB 2.0 port on the back of the GT 062E.
Front panel LED
The GT 062E front panel has a single bi-color LED. The LED will display solid blue when power is on. The LED
will flash blue when there is disk activity. The LED will flash or display a solid red color when error conditions
exits with the drives inside the array. Those error conditions are discussed in greater detail below.
NOTE: It is normal for the LED to flash red when the unit is powered on. Since the drives inside the GT 062E
take a few seconds to spin up, they are “offline” for a moment when the controller looks for them, and the red
warning LED comes on. When they fully spin up the controller sees that everything is normal, and turns the
red LED off.
Setting up the GT 062E
NOTE:
It is advisable that the Glyph Manager software be installed prior to following the instructions below.
1. Position the GT 062E by placing the unit on a flat, level surface, or install the unit into a rack with one of
Glyph’s rack kits. Caution: Speakers are magnetic devices; they can harm your data if they’re too close to your
hard drives or tapes.
2. Connect the power cable. Make sure that the power is off on all of your computer equipment and the GT
062E. Connect the power cable to the back of the GT 062E. Plug the three-prong plug into an appropriate
power receptacle, preferably with surge and spike protection.
3. Connect the FireWire 800, USB, or eSATA cable. Plug one end of the cable into your computer’s port, and
the other into the back of the GT 062E. Both FireWire 800 ports are functionally identical, so it doesn’t matter
which one you use.
