Powering On the Router

Powering On the Router
After the router is rack mounted, perform these tasks to complete the installation:
• Power on the router.
• Connect the front-panel ports. See the Connecting to SFP Modules section, to complete the installation.

Activating the DC Power Supply

Perform the following procedure to activate a DC power supply:
Procedure
Step 1
Remove the tape from the circuit-breaker router handle, and restore power by moving the circuit-breaker
router handle to the On (|) position.
Step 2
Verify power supply operation by checking if the front panel LED (PWR) is ON.
Note

Installing and Removing SFP Modules

These sections describe how to install and remove SFP modules. The modules are inserted into the SFP module
slots as depicted in Installing an SFP Module into an SFP Module Slot figure. These field-replaceable modules
provide interfaces.
See the Supported SFPs and PIDs for the list of SFP modules that the router supports. Each port must match
the wavelength specifications on the other end of the cable. For reliable communications, the cable must not
exceed the stipulated cable length.
Use only Cisco SFP modules on the Cisco router. Each SFP module has an internal serial EEPROM that is
encoded with security information. This encoding provides a way for Cisco to identify and validate that the
SFP module meets the requirements for the router.
For detailed instructions on installing, removing, and cabling the SFP module, see the SFP module
documentation.

Installing SFP Modules

Figure below shows an SFP module that has a bale-clasp latch.
Caution We strongly recommend that you do not install or remove fiber-optic SFP modules with cables attached
because of the potential damage to the cables, the cable connector, or the optical interfaces in the SFP module.
Disconnect all cables before removing or installing an SFP module. Removing and installing an SFP module
can shorten its useful life. Do not remove and insert SFP modules more often than is absolutely necessary.

If you are connecting a redundant DC power supply, it is recommended that each power supply be
connected to a separate power source in order to prevent power loss in the event of a power failure.
