Handling Fan-only Modules
depicts a DCS-7304 chassis with installed fabric modules (slots 1 and 2) and fan-only
modules (slots 3 and 4). Lock-levers are shown in the open (slot 3) and closed (slot 4) position
displays the position of the lock lever release screw (below the extended handles).
The fan direction indicator is located below the top handle. Refer to
for airflow configuration
requirements.
The following configuration is mandatory when fan-only modules are installed:
•
Slots 1 and 2 contain fabric modules
•
Slots 3 and 4 contain fan-only modules

B.3.1
Removing Fan-only Modules
This procedure describes the proper method for removing fan-only modules from the switch:
Step 1
Release the lock-levers from the module frame by rotating each handle’s release screw
counter-clockwise (
).
Step 2
Extend the lock-levers towards the top and bottom of the chassis (
Step 3
Use the lock-levers to pull the module three to four inches from the installed position.
Step 4
Return the lock-levers to the closed position.
Step 5
Grasp the module frame and pull the module until it is completely outside of the chassis.
B.3.2
Inserting Fan-only Modules
The fabric module insertion process is the inverse of the removal procedure. These instructions
describe the method of inserting the fabric module into a chassis.
Step 1
Grasping the module by its frame, place the module chassis railing that corresponds to the
slot where it is to be placed. The lock-levers should be in the closed position.
Step 2
Slide the module into the chassis until it’s within three to four inches of being fully inserted.
Step 3
Extend the lock-levers towards the top and bottom of the chassis.
Step 4
Continue inserting the module into the chassis.
Step 5
Return the lock-levers to the closed position, securing the module to the chassis.
Step 6
Secure each lock-lever handle to the module by inserting the release screw into the module
body and rotating clockwise.
