Describes hardware features of Cisco 8300 Series Secure Routers, including built-in ports, GE/SFP interfaces, removable modules, memory, power supply, LED indicators, ventilation, and slot, subslot, bay, and interface organization with detailed numbering schemes.
Built-in interface ports
The Cisco 8300 Series Secure Routers have multiple 10/100/1000 front panel ports and Small Form Pluggables.
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the Management Ethernet ports only to intra-building or unexposed wiring or cable. The intra-building cable must be shielded and the shield must be grounded at both ends. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of Primary Protectors in not sufficient protection in order to connect these interfaces metallically to OSP wiring.
RJ45 mGIG ports or SFP+ ports
The GE and SFP ports available on the Cisco 8300 Series Secure Routers are:
mGIG ports
C8375-E-G2:
The mGIG RJ-45copper interface ports support 100BASE-TX,1000BASE-T, and 2500BASE_T.
C8355-G2:
The mGIG RJ-45copper interface ports support 100BASE-TX,1000BASE-T, 2500BASE_T and 5000BASE-T.
SFP+ ports
The enhanced small-form-factor pluggable (SFP) ports support 10 Gbps SFP+ modules.
Two Gig RJ45 ports (suppoted only for C8355-G2)
The two Gig RJ45 port supports 10BASE-T, 100BASE-TX and 1000BASE-T.
Removable and interchangeable modules and cards
Service Modules (SMs), Network Interface Modules (NIMs), Pluggable Interface Modules (PIMs) and M.2 USB/NVMe storage fit into external slots and can be removed or replaced without opening the chassis.
Internal slots

Memory
See the Cisco 8300 Series Secure Routers product page on cisco.com for a list of supported modules and interface cards.
Memory
Cisco 8300 Series Secure Routers contain DIMMs that store running configuration and routing tables and are used for packet buffering by the network interfaces.
Memory in C8375-E-G2:
-
Boot/NVRAM—Stores the bootstrap program (ROM monitor) and the configuration register. The boot/NVRAM is not serviceable.
-
Internal memory—Internal bootflash memory
-
Removable M.2 card—Available in 32GBM.2 USB, 600GBM.2 NVMe SSD and 2TBM.2 NVMe SSD
-
DRAM options

Chassis ventilation
The chassis temperature is regulated with internal fans. An onboard temperature sensor controls the fan speed. The fans are always on when the device is powered on. Under all conditions, the fans operate at the slowest speed possible to conserve power and reduce noise. When necessary, the fans operate at higher speeds under conditions of higher ambient temperature and altitude.
Fans are present only on the C8375-E-G2 chassis.
Slots, subslots-bay, ports, and interfaces
The Cisco 8300 Series Secure Routers support interface modules: Service Modules (SM) and Network Modules (NIMs) and Pluggable Interface Modules (PIMs).
The C8375-E-G2 router supports Service Modules (SM) and Network Modules (NIMs) and Pluggable Interface Modules (PIMs).
In all cases, the device designates its interfaces using a 3-tuple notation that lists the slot, bay, and port. The 3-tuple value is zero based. An example of a 3-tuple is 0/1/2. This refers to slot 0, the second bay in slot 0 (the first bay is 0 so the second bay is 1), and the third port in bay 1. See the following table for more examples.

-
Slots and bays are numbered from the left to the right, and from the top to the bottom.
-
The USB port is named USB0. It doesn’t haveslot or bay numbers.
USB0 can be used to insert flash drives.
Slot numbering
Slots are numbered 0, 1, and 2.
Slot 0
These are the main features about Slot 0:
-
Slot 0 is reserved for integrated ports and NIMs, it can be used for either SM or NIM.
-
NIMs are designated by the number of the first slot that they occupy. A double-wide SM occupies two slots, but its designation is only the left-most slot number.
-
The ten GE ports (or native interface ports) always reside in slot 0 and bay 0. The ports are called Gigabitethernet 0/0/0, Gigabitethernet 0/0/1, Gigabitethernet 0/0/2, and Gigabitethernet 0/0/3 (up to as many ports supported on the particular router).
Subslot and bay numbering
-
Integrated devices, also known as integrated ports or FPGEs, and NIMs reside in a fixed section of bay 0.
-
Motherboard NIMs bays start at bay 1 because the integrated devices and integrated NIMs take up bay 0.
