Common RSP Hardware Features
This section discusses hardware features common to all RSPs. (For convenience, the RSP2, RSP4/4+,
RSP8, and RSP16 are referred to as the RSP with differences clearly noted.)

RSP LEDs
Several LEDs on the RSP indicate system and RSP status, as follows:
•
Normal LED—On when the RSP is receiving +5V, this LED indicates a successful boot; however,
it does not indicate the system has reached “normal” operation.

•
CPU halt LED—Off during normal operation, this LED goes on only if the system detects a
processor hardware failure.

The RSP controls the normal and CPU halt LEDs and turns them on in parallel to indicate that the
system is operational.

•
Master/slave LEDs—These LEDs indicate whether an RSP2, RSP4/4+, or RSP8 is the master or
slave in a system configured for the high system availability (HSA) feature.

Note
The master/slave LED and the HSA feature are not supported on the Cisco 7505 or Cisco 7576.
RSP DRAM
Dynamic random-access memory (DRAM) stores routing tables, protocols, and network accounting
applications.

2.
Do not mix memory sizes. If installing 2 DIMMs, both DIMMs must be the same size. If your router includes redundant RSPs, the RSPs should have the same
memory size.

3.
SRAM is not user-configurable or field-upgradable.
4.
A system configuration file is contained in NVRAM, which allows the Cisco IOS software to control several system variables.
5.
This 16-MB SIMM Flash memory is not supported on the RSP2, RSP4/4+, or RSP8.
6.
A 64-MB Flash Disk is the default shipping configuration for the RSP16 product.
