Figure 2. Securing a Device to a Shelf
Secure a False Front Panel
TIP: It is easier to secure a false front panel to the shelf after securing the devices but
before attaching the shelf to the rack.
The HRU 109 is shipped with one quarter-width and one eighth-width false front panel.
These panels can be used individually or in combination to fill in gaps left when smaller
devices are placed at the front of the shelf.
Additional false panels can be ordered:
Product Part Number
RFF 104 quarter-width false panel 70-338-01
RFF 108 eighth-width false panel 70-337-01
The panels leave a small (1/8 inch [0.3 cm]) gap on either side when they are installed.
