• USB 3.0 port: You can use this port to connect a mouse, keyboard, or any other USB device. Using a USB hub, you can connect more than one USB device to this port. Because this port is backward compatible, you can also use an older version of USB devices on this port.

• Ethernet management port for CPU: Use this port to connect to the CPU in your device.

• Front panel Gigabit Ethernet ports: There are a set of two dual ports GE0-0 and GE0-1. For those RJ45 ports, there is a corresponding fiber optic port. At a given time, the user can use either the RJ45 connection or the corresponding fiber optic port. There are a set of two copper ports GE0-2 and GE0-3. Those two ports support copper RJ45 only.

  Warning

  For connections outside the building where the equipment is installed, the following ports must be connected through an approved network termination unit with integral circuit protection: Gigabit Ethernet (GE). Statement 1044.

• Serial console port: This serial port provides a connection to initially configure the main system's CPU, including the NFVIS software that runs there, using a traditional serial terminal. The terminal should be configured for 9600 8-N-1.

Note

The speed and duplex configurations are dependent on the peer configuration. If the peer is set at a certain speed and duplex, NFVIS port is set to match that speed. Not all ports on ENCS 5000 series hardware devices support Automatic medium-dependent interface crossover (auto-MDIX) feature. Based on the port connected to the ENCS device, the cable type used to connect to the peer and the speed or duplex settings on the peer, you can try straight through and cross over cable.

LEDs for Gigabit Ethernet Ports

The front panel Gigabit Ethernet ports (numbered 4 in Figure 1) are a set of two dual ports: for every RJ45 port, there is a corresponding fiber optic port. There are four LEDs for the front panel Gigabit Ethernet ports (numbered 8 in Figure 1). The first two LEDs are for the first set of ports and the last two LEDs are for the second set of ports. If both RJ45 and fiber optic ports are enabled when the system boots, the fiber optic port is used and the RJ45 port is disabled.

The LEDs labeled EN indicates whether the corresponding ports are enabled.

The frequency of the blinks of the LEDs labeled S shows the speed of the corresponding ports. This table maps the blink frequency of a LED to the speed of the corresponding port.

Blink Frequency	Speed
No blink	No link
1 blink	10Mbps
2 blinks	100Mbps
3 blinks	1000Mbps

The following are the units of Cisco 5100 ENCS:

• M.2 storage module: This is a high capacity storage component on the motherboard. The OS is installable in this module. The storage capacity of this module is upgradeable. The different storage capacities that are currently available for this module are 64GB, 200GB, and 400GB. Other storage capacities might be made available in the future.

• DDR4 DIMM Slots: There are two DDR4 dual in-line memory module (DIMM) slots on the motherboard. Each slot can hold 8 GB or 16 GB memory module. The memory module in each of the slots can be upgraded to a maximum of 16 GB. As a result, you can have a maximum capacity of 32 GB.

The Cisco 5100 ENCS is available in these models:

Note	With the exception of M.2 drive and memory, other hardware features are common across all models.

Note	In the Cisco 5100 Enterprise Network Compute System, when the hardware units (for example, BIOS) are implemented separately, the compliance labels for each of them are different leading to label mismatch. To avoid the confusion, you must use the compliance label as the primary for the 74 TAN.

This section provides information on Cisco Small Form-Factor Pluggable (SFP) Modules in Cisco ENCS 5100. The switch Gigabit Ethernet SFP and SFP+ modules provide copper or optical connections to other devices. These modules are hot-swappable and provide the uplink interfaces. The SFP modules have fiber-optic LC connectors or RJ-45 copper connectors.

Use only supported SFP modules on the switch. Each module has an internal serial EEPROM that is encoded with security information.

Note	If non-supported SFP is plugged into the system, you need to reboot the system after removing the non-supported SFP for other SFPs to work normally.

Warning

Class 1 laser product. Statement 1008

Caution

Pluggable optical modules comply with IEC 60825-1 Ed. 3 and 21 CFR 1040.10 and 1040.11 with or without exception for conformance with IEC 60825-1 Ed. 3 as described in Laser Notice No. 56, dated May 8, 2019. Statement 1255

Caution

Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not view directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard. Statement 1056

The Cisco ENCS 5100 supports the following SFP modules:

^{1  A mode-conditioning patch cord, as specified by the IEEE standard, is required. Using an ordinary patch cord with MMF, 1000BASE-LX/LH SFP transceivers, and a short link distance can cause transceiver saturation, resulting in an elevated bit error rate (BER). When using the LX/LH SFP transceiver with 62.5-micron diameter MMF, you must also install a mode-conditioning patch cord between the SFP transceiver and the MMF cable on both the sending and receiving ends of the link. The mode-conditioning patch cord is required for link distances greater than 984 feet (300 m).}
