Setting the Link Rate Interface switch
Each FAStT700 Storage Server mini hub has a Link Rate Interface switch that is
used to select the host-side or drive-side mini-hub data transfer rates. The switch
settings are labeled 2 Gb per second and 1 Gb per second. Use a device with a
point such as a small flat-blade screwdriver or ballpoint pen to set the host-side or
drive-side mini-hub Link Rate Interface switch. See Figure 39.
The Speed indicator light is green when the data transfer rate of the Fibre Channel
loop is 2 Gb per second. The Speed indicator light is off when the data transfer rate
is 1 Gb per second. Figure 39 shows the location of the Link Rate switch and
indicator light.
