The HP ProCurve Switch xl PoE Module (J8161A) is a module for the HP ProCurve 5300 xl Switch and has 24 auto-sensing 10/100-TX RJ-45 ports. All 24 ports are capable of supplying PoE power. However, for the module itself to be able to supply PoE power it first must be connected to an EPS port on an HP ProCurve 600 Redundant and External Power Supply (J8168A), hereafter referred to as the HP 600 RPS/EPS.
The Switch 2600-PWR Series devices can be connected to an HP 600 RPS/EPS and receive full redundant power from the RPS part of the unit for switch operation, if the internal power supply in the switch fails. If multiple switches are connected to the RPS ports and several switches lose power at the same time, the switch attached to the lowest RPS port number receives power. The HP 600 RPS/EPS unit can provide all the power necessary to keep the switch running.
EPS power from the HP 600 RPS/EPS device is the PoE capability of the device and supplies backup and additional power for the ports of the 2626-PWR, 2650-PWR switch devices. It also provides PoE power to the HP ProCurve Switch xl PoE Module.
These switch devices are designed to be used primarily as high-density wiring closet or desktop switches. With these switches you can directly connect computers, printers, and servers to provide dedicated bandwidth to those devices, and you can build a switched network infrastructure by connecting the switch to hubs, other switches, or routers. In addition, they support the PoE standard, IEEE 802.3af, and can supply power over a twisted-pair cable to power devices such as telephones and wireless access points.
