This chapter describes how to install and remove small form-factor pluggable (SFP+), CPAK, and QSFP modules in the EPAs. This chapter contains the following sections:
The Cisco ASR 1000 series router support OIR of an SFP+, CPAK, or a QSFP module without removing the EPA or MIP.
The interface configuration is retained or recalled if an EPA, MIP, SFP+, or CPAK is removed and then replaced with one of the same type.
However, if the line card is already installed in the router and the system is operational, we recommend that you shut down the port using the interface config command before removing the SFP+, or CPAK, or QSFP modules.
Note The EPA supports only the SFP+ modules listed in the “Modular Optics Compatibilities” section. An SFP+ check is run every time an SFP+ module is inserted into an EPA, and only those SFP+ modules that pass this check are usable.
Before you remove or install an SFP+ module, read the installation information provided in this section and the “Laser and LED Safety” section.
SFP+ modules use one of four different latching devices to install and remove the module from a port. The four types of SFP+ module-latching devices are described in the following sections:
The bale clasp SFP+ module has a clasp that you should use to remove or install the SFP+ module. (See Figure 5-1.)
Figure 5-1 Bale Clasp SFP+ Module
To install this type of SFP+ module, follow these steps:
Step 1 Attach an ESD-preventive wrist strap or ankle strap according to the instructions provided.
Step 2 Close the bale clasp before inserting the SFP+ module.
Step 3 Line up the SFP+ module with the port, and slide it into the port. (See Figure 5-2.)
Figure 5-2 Installing a Bale Clasp SFP+ Module into a Port
Note Verify that the SFP+ modules are completely seated and secured in their assigned receptacles on the line card by firmly pushing on each SFP+ module. If the SFP+ module is not completely seated and secured in the receptacle, you will hear a click as the triangular pin at the bottom of the SFP+ module snaps into the hole in the receptacle.
To remove this type of SFP+ module, follow these steps:
Step 1 Attach an ESD-preventive wrist strap or ankle strap by following the instructions provided.
Step 2 Disconnect and remove all the interface cables from the ports and note the current connections of the cables to the ports on the line card.
Step 3 Open the bale clasp on the SFP+ module with your index finger in a downward direction, as shown in Figure 5-3. If the bale clasp is obstructed and you cannot use your index finger to open it, use a small flat-blade screwdriver to open the bale clasp.
Step 4 Grasp the SFP+ module between your thumb and index finger and carefully remove it from the port as shown in Figure 5-3.

Step 5 Place the removed SFP+ module on an antistatic mat, or immediately place it in a static shielding bag if you plan to return it to the factory.
Step 6 Protect your line card by inserting clean SFP+ module cage covers into the optical module cage when no SFP+ modules are installed.
The mylar tab SFP+ module has a tab that you pull to remove the module from a port. (See Figure 5-4.)

The CPAK transceiver module is a hot-swappable I/O device that plugs into the 1-Port 100 Gigabit Ethernet EPA (EPA-1X100GE). The modules have a total of 82 pins (40 pins on the top row and 42 on the bottom row) on the electrical interface and either a duplex SC or 24 fibers-MPO connector on the optical interface.
The following types of CPAK modules or adapters are supported:
Delivers 100-Gbps links over 24-fiber ribbon cables terminated with MPO/MTP connectors. It supports link lengths of 100m and 150m on laser-optimized OM3 and OM4 multifiber cables.
Note The EPA-CPAK-2x40GE supports only the CPAK-100G-SR10 and CAB-MPO24-2XMPO12 (breakout cable).
Supports 100-Gbps optical links over standard single-mode fiber (SMF, G.652) terminated with SC connectors. Nominal power consumption is less than 5.5W.
The LR4 module is IEEE 802.3ba-compliant and supports link lengths of up to 10 km over standard SMF, G.652. It delivers an aggregate data signal of 100-Gbps, carried over four wavelength-division multiplexing (WDM) wavelengths operating at a nominal 25 Gbps per lane in LAN mode. Optical multiplexing and demultiplexing of the four wavelengths are managed within the module.

Step 4 Slide the module out of the socket.
Step 5 Place the QSFP module into an antistatic bag.
Any contamination of the fiber connection can cause failure of the component or failure of the whole system. A particle that partially or completely blocks the core generates strong back reflections, which can cause instability in the laser system. Inspection, cleaning, and reinspection are critical steps to take before making fiber-optic connections.
