Installing The Hardware; Before You Start: Rack Safety Considerations - Dell C1048P Getting Started Manual

Installing the Hardware

To install the C1048P PE, mount it into a 19" wide, EIA-310-E compliant rack. You can install the C1048P
in a 1U 4-post front-rack or 1U 2-post (flush and center) rack configuration. Using a rack mount tray is
optional.
To install the C1048P PE in a rack:
1. (Optional) Install a rack mount tray in a 2- or 4-post rack.
2. Install the C1048P chassis in the rack using mounting brackets.
3. Connect the C1048P to a C9010 switch.
4. (Optional) Set up a C1048P stack by connecting to other C1048Ps.
5. Power up the system.
To connect the C1048P to a network after you install it in a rack and power it up, configure the initial
software settings. For more information, see
NOTE: Although Dell Networking strongly recommends that you install the C1048P in a rack, you
may install it on a flat surface as a free-standing device. The surface must be able to support the
weight of the C1048P and the PE cables. The C1048P ships with four self-adhesive rubber pads.
1. When installing the C1048P on a flat surface, attach the self-adhesive rubber pads on each
location marked on the bottom of the switch (unless you are using a rack).
2. Set the C1048P on a flat surface. Make sure that it has proper ventilation by leaving 5 cm (2
inches) on each side and 13 cm (5 inches) at the back.

Before You Start: Rack Safety Considerations

Before installing the C1048P in a rack, review the following rack mounting safety considerations.
WARNING: For complete safety information, read the safety instructions in your Safety,
Environmental, and Regulatory Information booklet before you begin. This document contains a
condensed summary.
• Rack loading — Overloading or uneven loading of racks may result in shelf or rack failure, causing
damage to the equipment and possible personal injury. Stabilize racks in a permanent location before
loading begins. Mount components beginning at the bottom of the rack, then work to the top. Do not
exceed your rack load rating.
• Power considerations — Connect only to the power source specified on the unit. When you install
multiple electrical components in a rack, ensure that the total component power ratings do not
exceed circuit capabilities. Overloaded power sources and extension cords present fire and shock
hazards.
• Elevated ambient temperature — If you install the system in a closed rack assembly, the operating
temperature of the rack environment may be greater than room ambient. Use care not to exceed the
50 degrees C maximum ambient temperature of the switch.
