Installing a filler panel in an empty interface module slot 

 

CAUTION: 

  If you are not to install an interface module in an interface module slot, keep the filler panel in the 

slot. 

  To prevent a filler panel from being drawn into the chassis when fan speed is high, use both 

hands to grasp the filler panel by its two sides during filler panel installation and removal on an 
operating device. 

 

To install a filler panel in an empty interface module slot: 

1. 

As shown by callout 1 in 

Figure1-5

, align and insert the filler panel into the empty interface 

module slot. 

2. 

As shown by callout 2 i

Figure1-5

, fasten the captive screws on the filler panel. 

As a best practice, use a torque of 5 kgf-cm (0.49 Nm) to fasten the captive screws.
