Installing and Replacing Hardware
Warning
The ports labeled “CNSL,” “AUX,” “ENET,” “Tx,” and “Rx (DS3)” are safety extra-low voltage (SELV)
circuits. SELV circuits should only be connected to other SELV circuits. Because the Basic Rate
Interface (BRI) circuits are treated like telephone-network voltage (TNV), avoid connecting the SELV
circuit to the TNV circuits.
Warning
This equipment is to be installed and maintained by service personnel only as defined by AS/NZS 3260
Clause 1.2.14.3 Service Personnel.
Warning
This product requires short-circuit (overcurrent) protection, to be provided as part of the building

or 2) while the housing is open.
Warning
VCCI Compliance for Class B Equipment (Japan).
This is a Class B product based on the standard of the Voluntary Control Council for Interference from
Information Technology Equipment (VCCI). If this is used near a radio or television receiver in a
domestic environment, it may cause radio interference. Install and use the equipment according to
the instruction manual.
Warning
Hazardous network voltages are present in WAN ports regardless of whether power to the router is
OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching
cables, detach the end away from the router first.
Warning
Metal objects heat up when connected to power and ground, and can cause serious burns.
Caution
Any module that is only partially connected to the backplane can disrupt system operation.
6.3.5.1 Installing an I/O Module
Complete the following steps to install and cable the I/O module on the Cisco 6260 chassis.
Tip
We recommend that you label each cable and wire at both ends to identify its destination.

card cage.
Step 2
Use a Phillips-head screwdriver to remove the I/O module retaining screws.
