Chapter 3 Router Hardware Description
Hardware Features Detailed Description
Hot Swapping SFP Modules
The SFP modules can be installed or removed while the router is on and operating normally.
Supported SFPs
Table 3-14
lists the supported SFP modules.
Note
See the
Cisco 1000 Series Connected Grid Routers Release Notes
for the most recent information about
supported hardware and software.
Specifications
Combo Ports
The combo ports are two gigabit Ethernet ports and two SFP ports on the router that are labeled
identically.
Figure 3-18
shows the ports.
The GE and SFP ports share the same physical ports or connections and are labelled identically on the
router (ETH 2/1, ETH 2/2) and in the software (GE 2/1, GE 2/2).
Table 3-15
describes the port naming
on the router and in software.
The Gigabit Ethernet ports support copper GE connections and the SFP modules support fiber optic GE
connections. Only one connection on each interface (ETH 2/1 and ETH 2/2) can be in use at any time.
These ports automatically detect the type of any connected cable (fiber or copper) and then switch to the
corresponding mode (fiber or copper).
