The following figure shows the hardware features seen from the front of the chassis.

1 |
Two vertical mounting brackets used to mount the chassis onto a rack |
4 |
3-kW AC power supplies (up to two without power redundancy or up to four with power redundancy) in slots PS 1 to PS 4 |
2 |
I/O modules (up to four) in slots LC 1 to LC 4 |
5 |
Chassis LEDs |
3 |
Supervisor modules (one or two) in slots SUP 1 and SUP 2 (identified in CLI output as Modules 27 and 28) |
6 |
Chassis handles (used only for positioning the chassis on the bottom support rails—do not use these handles for lifting the chassis) |
The following figure shows the hardware features seen from the rear of the chassis (one fan tray has been removed to show the fabric modules behind the fan trays).

1 |
Fan trays (three—one not shown in order to display the fabric modules located behind the fan trays) in slots slots FAN 1 to FAN 3 (identified in CLI output as Modules 41 to 43) |
4 |
Grounding pad |
2 |
Fabric modules (up to six—up to two behind each fan tray) in slots FM 1 to FM 6 (identified in CLI output as Modules 21 to 26) |
5 |
Chassis handles (used only for positioning the chassis on the bottom support rails—do not use these handles for lifting the filled chassis) |
3 |
System controllers (two) in slots SC 1 and SC 2 (identified in CLI output as Modules 29 and 30) |
