Rack mounting procedure
●
(1) Insert the 4 or 6 included rail length fixing screws (M4) and half-tighten them to hold the front
and rear rack rails in place. ①
There are two types of front rack rail: left (L) and right (R).
There are two types of rear rack rail.
(2) Adjust the length of rack rails to suit the rack, and then securely tighten the screws that were
half-tightened in step 1. ② The extension range of the rack rails is 465 to 790 mm.
(3) For EIA standard-compliant installation, attach the 8 included EIA rack fixing nuts (M5) to the
rack aligning them with the hole positions on the front (the side displaying "L" or "R") and the
back of the rack rails. ③ Then, use 8 EIA/JIS rack fixing screws (M5) to securely fasten them
to the rack. ④ The screw hole positions are the topmost and bottommost ones for both front
and rear.
For JIS standards, use a total of 4 screws to fix the rack; 1 EIA/JIS rack fixing flat-head screw
(M5) at a front position and a rear position on each of the left and right rack rails. ④ The screw
hole position is the one at the second from the top for both front and rear.
