Note Make sure the entire stripped end of each lead is inserted all the way into its receptacle. If any exposed wire at
the stripped end of a lead is visible after inserting the lead into its receptacle, remove the lead from the
receptacle, use the wire stripper to cut the stripped end of the lead, and repeat Step 3 through Step 5.
Step 6 Use a cable tie to secure the leads to the power supply.
When securing the ground, +V, and –V DC-input leads to the power supply faceplate, leave a small service loop in the
ground lead to ensure that the ground lead is the last lead to disconnect from the power supply if a great deal of strain
is placed on all three leads.
Step 7 Connect the ground, +V, and –V leads to the power source.
Important NPE-G1 and NPE-G2 Information
Following is some important NPE-G1 information that you need to know before you power on the router:
• The NPE-G2 has its own Cisco IOS software image with the prefix “c7200p-” in the software images file names, including
the boot image. The NPE-G2 does not boot up with a software image with the prefix “c7200-”. Previous network processing
engines, or the network services engine, do not boot up with the “c7200p-” boot image. They use the prefix “c7200-”.
• The RJ-45 ports and GBIC ports or SFP ports are both reported in software as GigabitEthernet 0/1, GigabitEthernet 0/2, and
GigabitEthernet 0/3. Only one of the pair of interface ports can be used at a time, for example, GE 0/2 or RJ-45 0/2.
• The I/O controller GE/E interface reports GE 0/0, and the I/O controller 2FE/E interface reports FE 0/0.
• If the RJ-45 port is in use, the EN (enabled) LED is on. If the GBIC or SFP is in use, the EN (enabled) LED is off.
• With the NPE-G1 or NPE-G2 and an I/O controller both installed, the I/O controller functionality on the NPE-G1 or NPE-G2
is shared with that of the I/O controller.
• The console and auxiliary ports on the NPE-G1 or NPE-G2 are disabled by Cisco IOS when an I/O controller is present; the
console and auxiliary ports on the I/O controller are active.
• Console port messages can be routed to the auxiliary port on either the NPE-G1 or NPE-G2 or on the I/O controller.
• The default media is the RJ-45 port. To change the media type, use the media-type command.
• Only the port selected by the media-type command is active. A cable attached to the other of the RJ-45 and GBIC or SFP pair
will be ignored. For example, if GBIC GigabitEthernet 0/2 is selected using the media-type command, RJ-45 GigabitEthernet
0/2 is ignored, even if a cable is attached to GBIC GigabitEthernet 0/2.
• The NPE-G1 or NPE-G2 uses no bandwidth points. If The NPE-G1 or NPE-G2 is in the router with an I/O controller, the I/O
controller also uses no bandwidth points. None of the Gigabit Ethernet interfaces on the NPE-G1 or NPE-G2 use bandwidth
points.
• The CompactFlash Disk on the NPE-G1 or NPE-G2 is available at all times, with or without an I/O controller installed.
• The USB ports on the NPE-G2 are available at all times, with our without an I/O controller installed.
Note The Gigabit Ethernet interfaces on the NPE-G1 or NPE-G2 do not support the Inter-Switch Link (ISL) VLAN
encapsulation protocol. We recommend that you use the IEEE 802.1Q VLAN encapsulation protocol as an alternative.
Where an application requires the use of ISL, this can be provided by the Fast Ethernet or Gigabit Ethernet port adapters
or I/O controllers.
