Fuse Replacement
The McIAS 1610 unit has three fuses which are located on the exterior backplane
(see Figure 1-3 in Volume I). These fuses have been selected to ensure safe operation
of the system and must always be replaced by fuses with identical ratings.
Following is the fuse rating detail:
F1 (3 amp, 60VDC) - This is the main fuse. When -48v system power is applied,
it is directed to the power supply through this fuse. The fuse is Littelfuse,
#401003 or equivalent. (Cognitronics P/N 70303320)
F2 (1 amp, 60 VDC) - This is the signal battery fuse which protects the system if
external power is applied. The fuse is Littelfuse, #401001 or equivalent.
(Cognitronics P/N 70303310)
F3 (1 amp) - This is the fuse which provides power to the SCSI bus terminator.
