Usb Port; Power Over Ethernet Module; G Cellular Data Wan Connectivity - Cisco 860 Series Hardware Installation Manual

Chapter 1 Product Overview
The Cisco 890 series routers contain 512 MB of DRAM by default (256 MB of onboard memory and a
single memory expansion slot that accommodates a PC2-5300, 256-MB or 512-MB DDR2 SODIMM,
for a maximum of 768 MB).
The Cisco 892F series routers contain 512 MB onboard memory and can contain an additional
512-MB PC2-5300 DDR2 SODIMM for a total or 1 GB system memory.

USB Port

The Cisco 860 series and 880 series routers have a single Universal Serial Bus (USB 1.1-compliant) port
located on the front panel. The USB port provides connection for USB devices such as security tokens
and flash memory.
The Cisco 890 series routers have two USB 1.1-compliant ports located on the front panel.
Fan
Some router models do not have a fan, while other models have either one or two fans.
The fans spin at full speed, as a diagnostic aid, immediately after the router is powered up. After the
router has booted, the fans spin as fast as necessary to minimize fan noise while maintaining a safe
internal operating temperature.

Power over Ethernet Module

The Cisco 880 series ISRs can include an optional Power over Ethernet (PoE) module that provides
power to 802.3af-compliant devices connected to FE ports 0 and 1.
The Cisco 890 series ISRs can include an optional PoE module that provides power to 802.3af-compliant
devices connected to FE ports 0, 1, 2, and 3.
The PoE module is an option available only for the Cisco 880 series and 890 series ISRs and requires a
48-V external power adapter.
This function can be added to an 880 or 890 series router by installing the PoE adapter card in the router
and inserting the PoE 48-V external power adapter.

3G Cellular Data WAN Connectivity

The 3G (Evolution Data Only [EVDO], Universal Mobile Telecommunications Systems [UMTS])
cellular interface is intended for use as a backup data link, but it can also be used as a primary WAN data
link. The 3G technology is third-generation wide-area cellular technology that is used in voice telephony
and broadband wireless data in a mobile environment.
The Cisco 88xG models come with a 34-mm express card slot ready for use with a commercial 3G card
radio. The 3G express card slot is located on the front panel. For a list of supported 3G cards, see the
