Installation preparation
Before you begin
Ensure the area where you install and use the switch meets environmental requirements.
You can install a single ERS 3510GT or ERS 3510GT-PWR+ switch on any flat surface that
can safely support the weight of the switch and attached cables. An ERS 3510GT switch
weighs 3.85 lb (1.75 kg). An ERS 3510GT-PWR+ switch weighs 5.9 lb (2.70 kg). Cable weight
varies for each installation.
You can install two ERS 3510GT or ERS 3510GT-PWR+ units together to form one standard
width rack-wide system using a 19 inch side-by-side Rack Mount Kit (ordered separately).
You can install the ERS 3524GT, ERS 3524GT-PWR+, ERS 3526T, or ERS 3526T-PWR+
switches in an equipment rack using the brackets provided.
