Caution:
z The S9500 series use multiple power systems, and you must turn off all of them
when removing the AC PSU.
z As the PSU of the S9500 series is heavy, use both hands to pull it out slowly and
gently, with one holding its handle and the other holding its bottom.
z If you do not want to install a PSU, insert a blank filler panel into the PSU slot for
dust-proofing and guaranteeing ventilation.
II. Installing AC PSU (S9505 as example)
Step 1: Remove the air filter from the PSU. Hold the handle of the PSU with one hand
and the bottom of the PSU with the other hand, and gently slide the PSU into the
chassis along the guides until it mates the backplane well.
Step 2: Fasten the captive screws at both sides of the PSU panel with a Phillips
screwdriver and cover the PSU with the air filter.
Step 3: Check that the power switch on the panel is in the “OFF” position and the clamp
holding the power cord connector has been pulled to the right.
Step 4: Insert the AC power cord accompanying the Switch into the socket on the PSU.
Step 5: Pull the clamp to the left to hold the power cord.
You can install the AC PSU on the S9502,S9508 and S9512 in the same way as on the
S9505.
