Step

Task

Dell Force10 recommends that one person hold the chassis in place

while a second person attaches the brackets to the posts.

Attach the bracket "ears" to the rack or cabinet posts, using two screws

for each bracket. Ensure the screws are tightened firmly.

Attach a Ground Cable to the S50N and S50V Chassis

The S50V and S50N switches have both AC (3-prong plug receptacle) and DC

(-48V terminal-type) connections on the back of the unit. They can use either

power source independently or in combination, with the DC source in a backup

mode (except for the 470W DC power supply). If you select AC and DC, the

switch will only use the DC source after the AC source fails.

NOTE: The rack installation ears are not suitable for grounding.

CAUTION: Grounding conductors must be made of copper. Do not use

aluminum conductors.

NOTE: Coat the one-hole lug with an anti-oxidant compound prior to crimping.

Bring any un-plated mating surfaces to a shiny finish, and coat with an anti-oxidant

prior to mating. Plated mating surfaces must be clean and free from contamination.

Attach a Ground Cable to the S50N-DC Chassis

The S50N-DC switches have two terminal blocks on the right side (instead of an

AC receptacle) for two DC power supply inputs. The terminal block on the

right, as you face the back of the chassis, is matched to the DC1 status LED on

the front left of the switch and the left block is matched to the DC2 status LED.
