outlets, the safety grounding conductor in each power cord
provides proper grounding only for the server. You must pro-
vide additional, proper grounding for the rack and other
devices installed in it.
Caution
Temperature : The operating temperature of the server, when
installed in an equipment rack, must not go below 5 °C or rise
above 35 °C. Extreme fluctuations in temperature can cause a
variety of problems in your server.
Ventilation : The equipment rack must provide sufficient airflow
to the front of the server to maintain proper cooling. It must also
include ventilation sufficient to exhaust a maximum of 4,100
Btu's per hour for the server. The rack selected and the
ventilation provided must be suitable to the environment in
which the server will be used.
Note: For vertical reference, every three screw holes on the
rack vertical mounting rail are equal to 1U (1.75 inches).
Mounting holes in the vertical rails of equipment racks are com-
monly spaced in a 5/8 x 5/8 x 1/2-inch sequence. Perform the
following steps carefully; brackets must be mounted with preci-
sion to allow room for the next server you install in a rack.
Assembling the Front and Rear Parts of Support Rails
The support rails are made of a front and a rear part. Those two parts may be adjusted
to fit the distance between the front and rear vertical rails of the rack.
1. Assemble the front (A) and rear (B) parts of the right support rail with 3 self
tapping screws (C) and 3 flat washers (D).
Note: When using self-tapping screws, we recommend you
tighten the screw for 3 quarters of a turn, and loosen for 1
quarter. Repeat this cycle until the screw is completely
tightened.
