Chapter 1 Product Overview
1-18
When the system power consumption of a switch (S7503E, S7506E, S7506E-V, or
S7510E) is less than the maximum output power of a 1U power module, you can first
insert the PWR-SPA power module adapters into the switch, and then insert 1U power
modules into the power module adapters. By doing so, you can use the 1U-high power
modules to power the switch.
A PWR-SPA power module adapter has the same physical dimensions with a 3U power
module.
1.2.4 Fan Tray
The S7502E, S7503E-S, S7503E, S7506E and S7510E switches provide chassis for
horizontal cards. The fan tray is installed on the right side of the front of the chassis.
The S7506E-V switch provides chassis for vertical cards. The fan tray is installed on the
upper of the front of the chassis.
