Mounting the SSA Switch
Enterasys S-Series Stand Alone (SSA) Hardware Installation Guide 2-3
To install the SSA switch in a rack using the SSA-FB-MOUNTKIT optional rack mount kit, follow 
the pre-installation discussion here including: “Power Supply Air Flow and Switch Fan Module 
Air Flow” on page 2-4 and “Reversing the Fan Module Air Flow” on page 2-5, before proceeding 
to “Optional Rack Mount Rail Kit Installation” on page C-1. 
You can install a SSA switch on a flat surface or in a rack. For more information about flat surface 
installation, see “Flat Surface Installation” on page 2-11. 
There are four possible rack mounting configurations as shown in Figure 2-1, based upon 
whether:
• The switch I/O ports side or the power supply side of the device face front
• The device is mounted flush with the rack posts or mid-mounted
