5.4 INSTALLING THE REAR POWER ENTRY CARDS
The power supply modules occupy the right-most slots on the rack
system (as viewed from the front). Refer to Figure 2 and follow the
instructions below to properly install the rear power entry cards into the
rack chassis. The rear entry cards must be in place and securely fas-
tened before the front cards can be installed.
To install a rear power entry card follow the steps below:
1.
Attach the earth ground wire (green with yellow tracer) of the first
power entry card (slot #17) to the stud along the inside wall of the
chassis, as shown. The star washer should be between the chas-
sis and the ground lug. Securely tighten the retaining nut. Failure
to connect the earth ground wire may result in a hazardous condi-
tion.
2.
Install the first power entry card into slot #17 in the rear of the
chassis. Secure the card using the two screws provided.
Steps 3-5 are for redundant applications only:
3.
Attach the ground wire of the second power entry card to the bare
metal side of the rear spacer. The spacer has two ground studs
and is powder-coat finished on only one side. The star washer
should be installed between the spacer and the ground lug.
Securely tighten the retaining nut.
4.
Secure the rear spacer to slot #16 using the two screws provided.
5.
Install the second power entry card into slot #15. Secure the card
using the two screws provided.
5.5 INSTALLING THE FRONT POWER SUPPLY CARDS (INITIAL
INSTALLATION)
To install a new front power supply card into the chassis, follow the
instructions below:
1.
Make sure that the associated rear power entry card is securely
installed into the rack chassis.
2.
Install a new power supply front card by carefully aligning the card
with the chassis guides. Gently slide the card, along the metal
rails provided, into the front of the chassis. The card connectors
will meet the mid-plane bus when the card is almost all the way
into the chassis.
3.
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.
4.
Use a flat blade screwdriver to tighten the captive screws.
5.
Repeat steps 1-4 for the second power supply card (redundant
applications only).
6.
Secure the front spacer to slot #16 using the two screws provided
(redundant applications only).
