installation in bays with mounting holes spaced at 2.54 cm (1.0 inch).
White adhesive-backed designation labels are shipped with the chassis for application at the

The fuse panel, as shown in
system tracer lamp LED circuitry in the bay. Power for each DSX-4U chassis is supplied
through a separate 0.5 Amp fuse. (Each LED draws 0.01 Amp, 24 LEDs in a chassis, equates to
a 0.24 Amp load.) The GMT fuse has a colored tab which is displayed when the fuse is blown.
The fuse panel also has a LED indicator which lights whenever any fuse on the panel is blown.
The fuse panel may also be connected to an external alarm system.
