Brocade Communications Systems ICX 7250, Руководство по установке оборудования

Страница: 64 / 119

Each RPS17 PSU can provide up to 740 W at 54 V and 120 W at 12 V. The RPS17 draws power from a standard AC source and converts
it to DC for use by the switches.
NOTE
The internal power supply of the ICX 7250 devices is not a field-replaceable unit (FRU). The devices must be shut down by
administrators for replacement.
Brocade recommends that you pay attention to the PoE or PoE+ port configuration of the device when connecting to an EPS4000. The
internal power supply of each PoE or PoE+ device has a maximum number of supported PoE or PoE+ ports. Brocade recommends that
when the EPS4000 is used as a redundant power source for the PoE device, that the maximum number of PoE or PoE+ ports of the
external power supply must not exceed the maximum number of PoE or PoE+ ports of the internal power supply capability of each
device.
The following devices are supported by the Brocade EPS4000:
∙
ICX 7250-24
∙
ICX 7250-24P
∙
ICX 7250-48
∙
ICX 7250-48P
NOTE
The ICX 7250-24G is not supported by the EPS4000.
EPS4000 features and benefits
∙
Hosts up to four hot-swappable RPS17 power supply units (PSUs).
∙
Provides N:1 power redundancy at 12 V with each PSU.
∙
Each RPS17 can deliver a maximum of 740 W at 54 V and 120 W at 12 V.
∙
A fully populated EPS4000 has 8 DC power ports that can monitor up to 16 switches simultaneously and provide 12 V
redundant power to four switches.
∙
Provides power redundancy at 54 V and true extended PoE power support.
∙
1:1 and 1:2 cables support 54 V or 12 V distribution up to 1 meter.
∙
Universal (100-240 V) AC line cord draws power from standard power outlet.
∙
The EPS4000 firmware is field-upgradeable.
∙
The power to the switches is maintained while the microcontroller unit (MCU) is being reset.
∙
The power distribution to the connected switches can be controlled per a priority scheme that you set.
EPS4000 front and rear panels
There are 32 LEDs on the front panel of the EPS4000 to indicate the status for the DC power on the 8 ports. 16 LEDs (Ex.y) are for the
54 VDC and the other sixteen (Rx.y) are for the 12 VDC supply. There is a reset button next to the LEDs. There are port LEDs for each of
the management ports. Both the serial port and the out-of-band Ethernet management ports use RJ-45 connectors. The slots for the
RPS17 PSUs are covered with slot covers. The slot cover must be removed to install the PSU.
