4.1.2.4. LaCie 12big Rack Fibre 8 Enclosure Not Rec-

ognized by Host Computer

1. Check that the interface cables from the RAID Controller to the

host computer are installed correctly.

2. Check that all drive carrier modules have been correctly in-

stalled and that the LEDs on all installed drive carrier modules

are illuminated green.

3. Check that there is a valid FC-AL signal present at the con-

troller’s connector by observing the state of Link Speed LEDs:

Amber = 8 Gbps, Green = 4 Gbps, and Orange = 1/2 Gbps

(Table 11).

The LED will be steady when there is a valid signal but no I/O activity

and will ﬂash when there is I/O activity. All FC signal LEDs will ﬂash

when there is no valid signal.

4. Check that the maximum cable lengths have not been exceed-

ed. The ﬁbre channel cable supported lengths are 2m, 3m, 5m,

50m. The mini-SAS cables supported lengths are .5m, 1m, 2m,

and 5m.
