spacer bar to secure the spacer bar.
8. Repeat Step 6 and Step 7 for the other spacer bar.

Installing QFX3008-I Interconnect Device Mounting Hardware on Two-Post Racks
Before you install the QFX3008-I Interconnect device in a two-post rack, you must first
install mounting hardware on the rack (see Figure 61 on page 232). The spacer bars are
not needed for this mounting option; however, you can leave them attached to the
front-mounting brackets.
NOTE: In a rack, the device uses 21 U. You can mount two QFX3008-I
Interconnectdevices on a 42 U rackprovided that the racks meet the strength
requirements to support the combined weight of the devices. If you are
mounting two QFX3008-I Interconnect devices on a rack, mount the first
device on the bottom of the rack.
