This section describes how to insert the power supply card into its slot. The power
supply card is inserted only after the system has been completely grounded and the
jumpers configured.
The power supplies used in the Coral IPx 500 consist of an AC powered PS500 AC or a
-48VDC powered PS500 DC power supply unit. Refer to
Figure 2-36 on page 2-60
,
Figure 2-37 on page 2-61 and Figure 2-38 on page 2-62
for power supply placement in
the card cage.
1. Verify that the cage ground wire is connected and the ground nut is tightened. See
page 2-46, Ground Wiring .
2. Verify that the PS500 power switch is in the OFF position (turned downwards),
see
Figure 2-41
.
3. Grasp the power supply with both hands, fingers near the top and bottom of the
power supply near the front panel.
4. Align the two guide ridges located on the right panel of the power supply (top
and bottom) in the card edge guides corresponding to the POWER SUPPLY
marking at the bottom of the card cage. Slide the power supply gently but firmly,
until fully inserted into the card cage.
5.
Fasten the two captive screws located on the top and bottom of the power supply
front panel, thus securing the card to the cage as well as grounding the unit.
10 Power Supply (PS500) Installation
The power supply card is heavy. Handle with care and do not drop.
Circuit cards contain static-sensitive circuitry and may be damaged or destroyed by
electro-static discharge (ESD). Always wear the static dissipating wrist strap connected
to the cage while handling circuit cards. See Figure 2-35 on page 2-55 . Hold circuit cards
by their edges and avoid touching contact surfaces. Handle with care and do not drop.
Do not proceed until the captive screws have been fastened to the cage. If the screws
are not fastened, the power supply unit will not be grounded, and could be subject to
hazardous voltages.
