Fan tray
section
The fan tray section is located at
the rear of the chassis.
Each fan tray on the S12500X-AF switch series, except
for the S12501X-AF and S12502X-AF, covers three
switching fabric module slots. The S12501X-AF and
S12502X-AF switches are integrated with a switching
fabric module and do not provide switching fabric
module slots.
The S12501X-AF switch has three fan tray slots FAN1,
FAN2, and FAN3. To ensure correct operation, install
three fan trays for the switch.
The other S12500X-AF switch models each have two
fan tray slots FAN1 and FAN2. The switch can operate
correctly with one fan tray. As a best practice, install
fan trays in both slots for redundancy and to reduce
noises.
Switching
fabric module
section
The switching fabric module slots
are behind fan trays. Each fan
tray covers three switching fabric
module slots.
The S12501X-AF and S12502X-AF switches have a
built-in switching fabric module, and do not require
installing a switching fabric module separately.
The other models come with all switching fabric
module slots empty. Purchase two to six switching
fabric modules for the switch. Purchase and install filler
panels in the empty switching fabric module slots.
The S12516X-AF, S12512X-AF, S12508X-AF, and
S12504X-AF switches
use slots 18 to 23, 14 to 19, 10
to 15, and 6 to 11 for switching fabric modules,
respectively.

To use an LSXM1TGS24FX1 LPU, the three
lowest-numbered switching fabric module slots
take precedence over other slots for module
