• (Optional) Any modules or disks not ordered with the chassis:
–
Cisco USB Flash memory module or Aladdin USB eToken Pro key
–
SFP module
–
CompactFlash Disk
Prepare for Workbench or Tabletop Installation
For a workbench or tabletop installation, verify the following before installing the router:
• The router is off the floor and has adequate ventilation.
• An adequate chassis ground (earth) connection exists for the router.
• The router has at last 3 inches (7.62 cm) of clearance at the inlet and exhaust vents (front and back of router).
• The router has 19 inches (48.26 cm) of clearance at the front and rear to allow for CompactFlash Disk, SFP module, USB
module and port adapter replacement or installation, or to access cables or equipment.
• The port adapter blank panel is installed if a port adapter is not installed. The slot must not be empty.
Prepare for Rack-Mount Installation
Before you begin the rack-mounting tasks, decide whether or not you want to front- or rear-mount the chassis, decide whether
or not you want to attach the cable-management bracket, and determine the type of rack—four-post or two-post—that you will
be using. Also determine if you have any optional field-replaceable units to install, particularly if you are using SFP modules,
port adapters, or CompactFlash Disks that are at your site and have not been ordered with the router. See the
“After Installation”
section on page 42
for instructions on installing these units.
If you ordered a port adapter, CompactFlash Disk, or SFP module with the router, they ship installed. If you ordered a USB Flash
memory module or Aladdin USB eToken Pro key, go to the
“After Installation” section on page 42 for installation information.
