Switching the Power Supply On and Off

The power supply on/off switch is located on the front panel.

When plugged in and switched on, a red front panel LED will glow.
Since the Model 1000R16 is a “hot swappable” rack, 

it is not necessary

for any cards to be installed before switching on the power supply

.

The power supply may be switched off at any time without harming the
installed cards.

NOTE:  

Please refer to the Model 1000RP Series User Manual 

AC 

and DC Rack Mount Power Supplie

s for fuse and power card 

replacement information.

4.2  INSTALLING THE MODEL 1205RC INTO THE CHASSIS

The Model 1205RC is comprised of a front card and a rear card.

The two cards meet inside the rack chassis and plug into each other by
way of mating 50 pin card edge connectors.  Use the following steps
as a guideline for installing each Model 1205RC into the rack chassis:

1.

Slide the rear card into the back of the chassis along the
metal rails provided.

2.

Secure the rear card using the metal screws provided.

3.

Slide the card into the front of the chassis.  It should meet the
rear card when it’s almost all the way into the chassis.

4.

Push the front card 

gently

into the card-edge receptacle of the

rear card.  It should “click” into place.

5.

Secure the front card using the thumb screws. 

NOTE:

Since the Model 1000R16 chassis allows “hot swapping” 

of cards, it is 

not necessary to power down

the rack when you 

install or remove a Model 1205RC.
