Installing the RPS Shelf into the Rack
To install an STK-RPS-150CH2 or STK-RPS-150CH8 into a 19-inch (48.3 cm) rack, you need the following:
• For the STK-RPS-150CH2: four customer-supplied screws to fasten the shelf to the rack rails.
• For the STK-RPS-150CH8: ten customer-supplied screws to fasten the shelf to the rack rails.
After installing the power supplies as described in Installing an STK-RPS-150PS in an RPS Shelf on page
281, rack mount the RPS shelf as follows:
1. Refer to the installation guidelines (Guidelines for Rack Mount Installation).
2. Install the RPS shelf into the rack (Rack Mounting the RPS Shelf on page 283).
3. Connect the RPS cables and AC power cords of the power supplies (Connecting the RPS Cable and
AC Power Cord on page 284).
