The board rack consists of board slots and a system board.
The boards are inserted vertically into the DCRS-7608 10 unit boards are provided.
These include 2 management slots in the middle for management switch modules,
marked specially in red as M1 and M2. The other eight board slots are network slots for
various network interface modules, sequenced as 1 to 8 from left to right.
A reset button (printed on the panel as Reset), hot swap button (printed on the panel
as SWAP), board power indicator (printed on the panel as PWR) and board running status
indicator (printed on the panel as RUN) are provided for each
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

1.4.1.2.2 Power Supply
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.
1.4.1.2.3 Ventilation and Cooling System
The operating ambient temperature of the DCRS-7608 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,
