External Interfaces
The external physical interfaces on the front panel of the chassis are given below:
Network Interfaces
The network interfaces are provided through fixed ports.
- GE SFP ports—supports 100/1000 modes
- GE Copper RJ-45 ports—supports 10/100/1000 operation. All eight copper RJ-45 ports support PoE/PoE+/UPoE with overall power budget of 180 W.
Note |
PoE is not supported when the system is powered with 24 V DC. |
- 10GE SFP+—supports 10G/1G mode depending on the SFP+/SFP in the network interface slot.
At 1G mode, it supports only 1000BaseX.
Network Timing Interfaces
- 10MHz input or output—Miniature coaxial connectors for 10MHz timing (input or output). You can use this interfaces with an external GPS device to send or receive clocking from the chassis
- 1PPS input or output and ToD input or output—This interface is used for input or output of time-of-day (ToD) and 1PPS pulses. ToD format includes both NTP and IEEE 1588-2008 time formats.
The same RS422 pins for 1PPS and TOD are shared between input and output directions. The direction for each can be independently configured through software.
- GNSS RF IN—This interface is used to connect the external GPS antenna to the in-built GPS module.
External Alarm Inputs
The chassis supports four dry contact alarm inputs through an RJ-45 jack on the front panel.
Each alarm input can be provisioned as critical, major, minor, or can be configured for normally open or normally closed.
Management Interfaces
The following management interfaces are supported:
Management ENET Port
A single management copper ENET port supporting 100/1000Base-T operation is provided on the front panel. It uses a standard RJ-45 jack.
RS232 Console Port
The RS232 console port provides transmission (Tx), reception (Rx), and ground (Gnd).
Note |
The RS232 console port is enabled only through the Cisco-designed cable adapter USB type A cable to RJ-45 adapter cable. To use this port, disable the flow control on the terminal. |
Caution |
Do not plug the USB-to-RJ45 adapter cable in the USB Memory port. |
USB Console
A single USB 2.0 Type-A receptacle on the front panel of the chassis provides console access to ROMMON, Cisco IOS-XE and diagnostics. While it uses the Type-A connector, it operates as a USB peripheral only for connection to an external host computer. This interface requires the use of a Type-A to Type-A connector instead of a standard USB cable.
Note |
Use of the USB console is mutually exclusive of the RS232 console port. This interface requires the use of a Type-A to Type-A USB cable. |
USB Mass Storage
A single USB 2.0 Type-A receptacle on the front panel of the chassis allows external USB mass storage devices, such as standard USB flash drives. This interface is used to load images, load or store configurations, write logs, and so on.
Note |
More than 8 GB is not supported in ROMMON mode, |
Zero Touch Provisioning Button
The Zero Touch Provisioning (ZTP) button on the front panel initiates the ZTP process on a short press of less than eight seconds. Pressing the ZTP button for more than eight seconds causes a board reset.
RS232 Auxiliary Console Port
The RS232 Aux console port provides transmission (Tx), reception (Rx), and ground (Gnd).
Note |
The RS232 Aux console port is enabled only through the Cisco-designed cable adapter from USB type A cable to RJ-45 adapter cable. This is a debug-only port. it is recommended that this port be used by field service engineers only. |
Power Supply and Fans
The chassis supports AC, DC, or a combination of both power supplies in a 1+1 redundant configuration.

Note |
This product requires surge protection as part of the building installation. To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, an external surge protective device (SPD) is required at the AC power service equipment. |
Note |
For DC systems, if a surge of more than 500 V is expected, add an appropriate external surge protective device. |
The chassis has a single fan-tray with four fans. The system is designed to operate at its maximum operating temperature of 70º C, in case of failure of a single fan operating temperature of 65º C. The fan tray is field-replaceable.
LED Indicators
This section describes the different types of LEDs and their behavior.
PWR and STAT LEDs
The PWR LEDs are available on the front panel. These LEDs provide power on the board (PWR) status. During power up state, these LEDs provide booting status and report errors.

Note |
The CPU management port LED on the right is non-functional and hence doesn’t indicate any port status. |

Online Insertion and Removal
This chassis supports the following OIR operations:
- When an SFP is removed, there is no effect on traffic flowing on other ports.
- When an SFP is installed, the system initializes that port for operation based upon the current configuration. If the inserted SFP is incompatible with the current configuration for that port, the port does not become operational until the configuration is updated.
- Both power supplies are installed and active and the load may be shared between them or a single PSU could support the whole load. When a power supply is not working or the input cable is removed, the remaining power supply takes the entire load without disruption.
Caution |
Do not remove or replace the fan tray with the chassis powered on. |
