B
blank filler plate
An empty panel used to fill vacant subslots on a SIP. For proper operation, a SIP should be fully
installed with either functional SPAs or blank filler plates.
F
FPD
Field-programmable device. General term for any hardware component implemented on router cards
that supports separate software upgrades. SIPs and SPAs must have the right FPD version to function
properly; an FPD incompatibility will disable all interfaces on the SPA or all SPAs within the SIP.
FPD image package
An FPD image package is used to upgrade FPD images. Whenever a Cisco IOS image is released that
supports SPAs, a companion SPA FPD image package is also released for that Cisco IOS software
release.
full-height,
double-wide
Describes the dimensions of a SPA that occupies four standard, half-height SIP subslots or two
full-height SIP subslots.
O
OIR
Online insertion and removal. Feature supported by SIPs and SPAs allowing removal of the cards while
the router and the cards are activated, without affecting the operation of other cards or the router.
Although this removal can be done while the SIP or SPA is activated, it is generally recommended that
you gracefully deactivate the hardware using the appropriate commands for your platform prior to
removal of the hardware.
S
SFP
Small form-factor pluggable optical transceiver. A type of fiber optic receptacle device that mounts
flush with the front panel to provide network connectivity.
single-height
Describes the dimension of a SPA that occupies a single SIP subslot, or half of the SIP.
SIP
SPA interface processor. A SIP is a platform-specific carrier card that inserts into a router slot like a
line card. A SIP can hold one or more SPAs in its subslots, depending on the SIP type. The SPA
provides the network interface. The SIP provides the connection between the route processor (RP) and
the SPA.
