After the DC power supply leads are properly connected and
power is applied, the green "12V" LED on the 1001RPSM-R48V front
panel will be illuminated and the fan will operate. There is no on/off
switch.
5.9 SERVICE PROCEDURE - REPLACING A 1001RPSM-RUI
FRONT CARD
This section describes the procedure for replacing an already-
installed 1001RPSM-RUI AC power supply front card. A flat blade
screwdriver is required to remove and install the card.
To replace an already-installed 1001RPSM-RUI AC power supply
front card, follow the detailed instructions below:
1.
Loosen the two front-panel captive securing screws. Do not
remove the screws from the card.
2.
Using two hands, grasp the captive screws and slowly separate
the card from the rack until the front panel is approximately ONE
INCH from the edge of the rack chassis. This disconnects the
front card from the AC voltage source.
DO NOT COMPLETELY
REMOVE THE CARD FROM THE RACK CHASSIS!
3.
After a minimum of three minutes have elapsed after disconnect-
ing the AC voltage source, the front card may be safely removed
from the rack chassis.
4.
Install a new 1001RPSM-RUI front module by carefully aligning it
with the chassis guides. Gently slide the card into the chassis
along the metal rails provided. The card connectors will meet the
mid-plane bus when the card is almost all the way into the chassis.
5.
After the connectors meet, gently apply even pressure to the top
and bottom of the panel to seat the card. Do not force the card
into the chassis. This may damage the connector pins.
6.
Tighten the captive screws. The green "12V" LED should be illu-
minated and the fan should operate.
5.10 SERVICE PROCEDURE - REPLACING A 1001RPSM-R48V
FRONT CARD
Follow the same procedure as outlined in the section "REPLAC-
ING A 1001RPSM-RUI FRONT CARD". Since the 1001RPSM-R48V
uses only non-hazardous, low DC voltage, it may be safely removed
from the rack chassis immediately after loosening the captive screws.
WARNING!
Hazardous voltages exist in the primary cir-
cuits. Beware of internal lethal voltages due to charged capaci-
tors even after the AC input is disconnected. A minimum of 3
minutes should be allowed after AC input power is disconnect-
ed before removing or handling the front power supply module.
WARNING!
Hazardous voltages present. To avoid electric
shock or personal injury, adhere to the module replacement
instructions exactly as stated.
