Installing the S-DC-PS Power Supply
When you receive your S4 chassis, a coverplate will be in place over all power supply slots except
PS1. This slot is left open for your convenience when installing the first power supply.
You must install the power supplies in the slots labeled PS1, PS2, PS3, and PS4 at the bottom of the
chassis. If you intend to install a single power supply, you must install it in the power supply slot
labeled PS1.
A Phillips screwdriver is required to install the S-DC-PS power supply in an S4 chassis.
To install S-DC-PS power supplies in your S4 chassis:
1. Attach the ESD wrist strap shipped with your S4 chassis to your wrist and plug the cable from
the ESD wrist strap into the ESD grounding receptacle on your chassis.
2. Locate the PS1 power supply slot, as shown in Figure 1-2 on page 1-3.
3. Ensure that the breaker switch on the DC power supply is set to Off.
4. Hold the power supply by placing one hand on the handle located on the front panel and
using your other hand to support the power supply.
5. Holding the power supply with the terminal studs on the left and the handle on the right,
align with the slot opening.
