Some PICs accept small form-factor pluggables (SFPs), which are fiber-optic transceivers
that can be removed from the PIC. Various SFPs have different reach characteristics.
You can mix them in a single PIC and change the combination dynamically. SFPs are
hot-removable and hot-insertable. ,
The number of ports on a PIC depends on the type of PIC. You can install up to four PICs
in each Type 1 FPC and one PIC in each Type 2 FPC. Blank PICs resemble other PICs but
do not provide any physical connection or activity. When a slot is not occupied by a PIC,
you must insert a blank PIC to fill the empty slot and ensure proper cooling of the system.
PICs installed on Type 1 FPCs and Type 2 FPCs are hot-removable and hot-insertable.
Most PICs supported on the M40e Multiservice Edge Router have the following
components:
One or more cable connector ports—Accept a network media connector.
LEDs—Indicate PIC status. Most PICs have an LED labeled
Some PICs have additional LEDs, often one per port. The meaning of the LED states
differs for various PICs. See each PIC description for more information about the LEDs.
Offline button—Prepares the PIC for removal from the FPC when pressed.
Type 1 PICs—The offline button for each PIC is next to it on the FPC.
Type 2 PICs—The offline button is on the PIC faceplate.

FPCs are hot-removable and hot-insertable, as described in "M40e Field-Replaceable
Units (FRUs)" on page 157. When you remove or install an FPC, packet forwarding halts
for about 200 ms while the Packet Forwarding Engine adjusts to the change in the amount
of memory available in the pool located on and shared by all FPCs. When you install an
FPC into a functioning router, the Routing Engine downloads the FPC software, the FPC
runs its diagnostics, and the PICs housed on the FPC are enabled. Forwarding continues
