General Architecture 13
The Switch 8807 uses a passive backplane, which provides five I/O module
interfaces, two fabric interfaces, one fan interface, and three -48V power
interfaces (two for PSUs and one for PoE entry module).
■ Switch 8810
The Switch 8810 uses a passive backplane, which provides eight I/O module
interfaces, two fabric interfaces, one fan interface, and three -48V power
interfaces (two for PSUs and one for PoE entry module).
■ Switch 8814
The Switch 8814 uses a passive backplane, which provides 12 I/O module
interfaces, two fabric interfaces, two fan interfaces, and three -48V power
interfaces (two for PSUs and one for PoE entry module).
AC Power System
n
■ The Switch 8800 Family supports AC power inputs.
■ The Switch 8800 Family supports 1+1 power supply redundancy.
■ The PSUs of the Switch 8800 Family are online-swappable.
The Switch 8800 Family supports AC power inputs. The power frame is at the
bottom of the chassis, with a height of 3U. In the same slot, you can insert an AC
PSU. The power frame is in different compartment from the functional board
frame and connected to the latter with cables, which are routed along the back of
the chassis. The power supply is cooled by built-in fans of the PSUs, which draw air
into the chassis from the front and exhaust air out of the chassis from the back.
PoE Power Supply The Switch 8800 Family supports Power over Ethernet (PoE). With this feature, a
Switch 8800 Family switch equipped with an external PoE power supply and
PoE-capable modules can deliver 48 VDC to its remotely powered devices (PDs,
such as IP phones, WLAN APs and network cameras) through twisted pairs.
■ The Switch 8800 Family can supply power to remote PDs through the Ethernet
electrical ports on the I/O modules. Each I/O module can simultaneously supply
power to up to 48 PDs with the maximum distance of 100 m (328.1 feet).
■ Each Ethernet port can deliver up to 15.4 W to its PD.
