Install Guide

1U two-post installation
You can install the switch in 1U front-rack, four-post or two-post configurations. The following is an example of a front-rack
configuration.
For the 1U two-post flush or center configurations, slide the system into the rails in the same manner as the four-post
configurations.
1U front-rack installation
Configure the rails that are attached to the system:
1. Attach the inner chassis members switch rails to the system, items 1 and 2.
The following illustration, item 3, shows the detail for the front standoff with the locking tab.
Figure 14. Switch rail attachment
2. After you have installed both switch rails, line them up on the previously mounted Ready-Rails and slide the switch in until it
is flush with front of rack.
About three inches prior to full insertion, the rail locking feature engages to keep the switch from inadvertently sliding out of
the rack and falling.
NOTE: Do not the use the mounted Ready-Rails as a shelf or a workplace.
Ground wire installation
After you have installed the S4048T-ON switch in a rack, complete the installation of the ground wire.
You previously installed the GND lug and bracket assembly, with ground wire attached, to the S4048T-ON chassis, see Ground
lug and bracket installation.
Provide the following items:
● One 2-hole UL-certified GND lug to attach ground wire to rack
● Two National Electric Code (NEC) compliant screws to attach the GND lug to the rack
● Antioxidant compound
● Crimping tool
1. Measure and cut a length of wire sufficient to reach between the system-installed GND lug and the rack-end GND lug.
