Electrical Considerations
When installing the 2Gb SANbloc Series the following
electrical considerations must be applied.
Circuit Overloading Care should be taken to ensure that the current does not
exceed the rating of the power source circuitry. This
includes cabling, power distribution units, filters and any
other devices through which the main current flows. The
electrical power rating of the enclosure is 100 - 240 VAC,
10 - 5 Amps (50/60 Hz), and this must be added to the power
demands of any other electrical devices installed in the
equipment rack to arrive at a total power consumption
figure. In addition, surge currents must be catered for. Disk
drives may consume twice the amount of current at start-up
time as they do during steady state operation.
Setting Fibre Channel Loop Speed (2Gb or 1Gb)
The 2Gb SANbloc Series can be operated with fibre channel
loop speeds of either 2Gb or 1Gb. The loop speed is set
through the use of a jumper (JP2) located on the LS Module.
Note: If the enclosure has dual LS modules the following
procedures must be applied to both LS modules.
2Gb Operation To set the fibre channel loop speed to 2Gb operation:
1 Remove the LS Module from the front of the enclosure.
2 On the LS Module locate the jumper position JP2 (Figure 2-1).
3 Install a jumper at JP2.
4 Replace the LS module.
