EES4710BD 10 Slots L2/L3/L4 Chassis Switch
the panel as RUN) are provided for each board. On the Main Control cards there is Master-Slave
indicator (printed on the panel as M/S) There is also a power module status indicator (printed on the
panel as Power: Fail/OK), fan assembly status indicator (printed on the panel as Fan: Alarm/OK),
and interface status indicators for corresponding management interfaces and network interfaces
(printed on the panel as Link and Act).
The ES4710BD system board is an essential part of the switch, located inside the switch and
providing interconnectivity between the management switch modules (short for management card)
and network interface modules (line card), and for all management and control signals.
When powered by AC sources, the 110V/220 VAC input power supplies and corresponding AC
distribution box should be used. The acceptable input power ranges from 90 ~ 264 VAC at 50 ~ 60
Hz. The maximum output power of each power module is 600W.
When powered by DC sources, the -48 VDC input power supply and corresponding DC distribution
box should be used. The acceptable input power ranges from -36 V ~ 72 VDC. The maximum
output power of each power module is 600W.
The operating ambient temperature of the ES4710BD is 0 ~ 40°C, the thermal design of the
equipment can ensure that the surface temperature of the device will not exceed the 50°C to 80°C,
the highest temperature allowable.
The switch uses fan assemblies to disperse heat, with the air flow being drawn in through the bottom
section and out through the upper section to facilitate air circulation, so that the switch can maintain
normal operation under specified environmental conditions. Three fan trays are attached to the fan
tray slots above the board rack, and ventilation is provided via 6 axial fans that pump out air. Fan
trays are hot swappable for maintenance, their status are indicated by the FAN indicators on the
main switch panel. In addition, dust gauze is provided under the board rack for filtering the air
circulating through the rack. The dust gauze can be unplugged and removed through the front for
maintenance.
The following six cards for the ES4710BD are currently available:
z Main control card (EM4710BD-AGENT): The central switching and controlling module
for the ES4710BD. System status control, switch management, user access control and
administration, and network operation maintenance are performed here.
z 12 copper Gb ports line card (EM4700BD-12GT-RJ45): supporting 12 1000Base-T
copper ports for layer 2 and layer 3 switching and routing.
