Slot Distribution

Two SIC slots can be combined into one WSIC slot by removing the guide rail between them.
Two SIC slots and the WSIC slot below them can be combined into one XSIC slot by removing the guide rails.
After two slots are combined into one, the new slot ID is the larger one between the two original slot IDs.

Figure 4-256 shows slot distribution of AR2220-DC routers.

Interface Description

CON/AUX Interface

The console interface of a router can connect to an operation terminal for onsite configuration. An AUX interface can connect to a remote management center through a modem for remote configuration. Table 4-678 lists the CON/AUX interface attributes.

Table 4-678 CON/AUX interface attributes

Attribute	Description
Connector type	RJ45
Standards compliance	RS232
Working mode	Full-duplex Universal Asynchronous Receiver/Transmitter (UART)
Data equipment type	Data circuit terminal equipment (DCE) AUX interface: data terminal equipment (DTE)
Cable type	Console Cable

Mini USB Interface

A Mini USB interface can connect to an operation terminal for onsite configuration. The Mini USB interface and console interface cannot be used at the same time. By default, the console interface works. Table 4-679 lists attributes of a Mini USB interface.

Table 4-679 Mini USB interface attributes

Attribute	Description
Connector type	Mini USB-B-angle
Standards compliance	USB2.0
Working mode	Device

GE Electrical Interface

A GE electrical interface (10/100/1000 Mbit/s auto-sensing) transmits and receives Ethernet services at 10 Mbit/s, 100 Mbit/s, or 1000 Mbit/s. Table 4-680 lists attributes of a GE electrical interface.

Table 4-680 GE electrical interface attributes

Attribute	Description
Connector type	RJ45
Interface attribute	MDI/MDIX NOTE: MDI stands for medium dependent interface, an Ethernet interface connection mode. Ethernet interfaces of most network adapters are MDI interfaces. MDIX stands for medium dependent interface crossover, a version of MDI. MDIX interfaces are usually used on hubs or LAN switches.
Standards compliance	IEEE802.3, IEEE802.3u, IEEE802.3ab
Frame format	Ethernet_II, Ethernet_SAP, Ethernet_SNAP
Network protocol	IP
Cable type	Ethernet Cable

GE Combo Interface

A GE combo interface consists of an optical Ethernet interface and an electrical Ethernet interface on the panel. The two interfaces have only one internal forwarding interface. The electrical and optical interfaces are multiplexed, and only either of them can work at a time. When either of the Ethernet interfaces is working, the other interface is shut down.

The GE electrical interface (10/100/1000 Mbit/s auto-sensing) transmits and receives services at 10 Mbit/s, 100 Mbit/s, or 1000 Mbit/s. It must be used with an Ethernet Cable.
The GE optical interface (100/1000 Mbit/s auto-sensing) transmits and receives services at 100 Mbit/s or 1000 Mbit/s. It must be used with an Optical Fiber, GE eSFP Optical Modules, or FE SFP/eSFP Optical Modules.

In V200R008C30 and earlier versions, a combo interface works as an electrical interface and uses a network cable to transmit and receive data by default.
In V200R008C50 and later versions, a combo interface works in auto mode and automatically works as an optical or electrical interface by default.

USB Interface (Host)

A USB interface provides up to 480 Mbit/s upload and download rates. Table 4-681 lists attributes of a USB interface.

Table 4-681 USB interface attributes

Attribute	Description
Connector type	Type A
Standards compliance	USB2.0
Working mode	Host

Heat Dissipation

The AR2220L-DC router has built-in fans to cool the system. The fans are not pluggable.

Seen from the front panel, the airflow is left to right, as shown in Figure 4-258. Cold air flows into the router from the left side and is exhausted from the right side, taking away heat generated by the router.
