GE-DCARD-ESW: This optional 1000BaseT Gigabit Ethernet port for NM-16ESW and NMD-36-ESW can be
●
used for a gigabit connection for a file server or for intra-chassis stacking of the Cisco EtherSwitch module.
Stacking is supported in Cisco IOS release 12.2(11)T and beyond.
PPWR-PS-CHASSIS: The power chassis is an external chassis that can support up to four 360W power
●
supplies, which can provide power over ethernet to Cisco phones or wireless access points. This chassis can
support up to 144 IP phones @ 10W per port (or less devices at <10W per port). The external PPWR-PS-
CHASSIS is for use with the Cisco 2600 and 3600 Series. The 2800, 3700, and 3800 Series internal power
supply can be upgraded to provide Power over Ethernet and the external chassis is not used for these routers.
Also available is a custom cable that connects the power supply to the Cisco EtherSwitch Modules. Cable
options allowing for power supply redundancy are also available. The power over ethernet works over standard
Category 5 unshielded twisted-pair (UTP) cable up to 100 meters and allows direct power instead of using wall
power with a transformer. This allows customers to use existing Category 5 UTP installations. The Cisco
EtherSwitch Module power over ethernet implementation passes the required U.S. and international safety
regulations and compliance measures.
NM-16ESW-PWR and NMD-36ESW-PWR: The 16- and 36-port Ethernet switch modules with power daughter
●
cards support 48V inline power of IP telephones when either purchased with an external power chassis or when
used with an internal power supply. This combination of components enables IP phones to be plugged into any
EtherSwitch module port. Also, the integrated Cisco power over ethernet for the 10/100BaseTX autosensing
ports provides DC power to devices that can accept power over traditional UTP cabling (such as the Cisco 7900
Family of IP phones). This allows a standard RJ-45 jack to be powered from this EtherSwitch module source
rather than having a separate plug into an AC wall outlet. Delivery of -48V power must be made to the 16-port
Ethernet switch. This daughter card is required for power over ethernet. An internal or external power supply is
also required.
PPWR-PS-360W: This single 360W power supply for the Cisco EtherSwitch module line power can be added to
●
a power chassis or can added internally into the Cisco 3700 Series router to power additional IP phones or
wireless access points. Each power supply supplies up to 360W and can power up to 36 IP phones. For the
Cisco 2800 and 3800 Series an upgrade to the internal router power supply is required and the PPWR-PS-
360W is not used.
