Attaching the mounting brackets and chassis rails to the chassis
1. Align the mounting brackets with the screw holes in the chassis. Use M4 screws (provided) to
attach the mounting brackets to the chassis.
{
To install the mounting brackets at the power module-side mounting position, see Figure 9
and Figure 10 .
{
To install the mounting brackets at the network port-side mounting position, see Figure 11
and Figure 12 .
2. Align the chassis rails with the rail mounting holes in the chassis:
{
If the mounting brackets are in the power module-side mounting position, align the chassis rails
with the screw holes at the front of the side panels (see
Figure 9 and Figure 10 ).
{
If the mounting brackets are in the network port-side mounting position, align the chassis rails
with the screw holes at the rear of the side panels (see
Figure 11 and Figure 12 ).
3. Use M4 screws (provided) to attach the chassis rails to the chassis.
NOTE:
• Secure the mounting brackets and chassis rails to both sides of the chassis in the same way.
•
To install the mounting brackets at the network port-side mounting position on the S7502E-XS and
S7504E-XS switches, use the four screw holes nearest to the network port side. To install the mounting
brackets at the power module-side mounting position on the S7502E-XS and S7504E-XS switches, use
the four screw holes nearest to the power module side.
