Connecting Power Cords
Redundant power connectors are located at the rear of the chassis as shown in Figure 1-8 on page 1-9
and Figure 1-12 on page 1-13 . Power connections have the following properties:
•
Chassis power inlets accept 120 VAC or 220 VAC or –48 VDC power supplies.
•
The CDE205, CDE220chassis contain two VAC or VDC power ports contain three VAC or VDC
power ports.
Caution
Although CDEs accept both AC and DC power modules, the system does not allow mixing of AC and
DC power modules in one system.
Do not apply AC power to DC power modules.
Server Types
Both VDS-IS and VDS-TV consist of servers (CDEs) that are connected through Ethernet switches. The
Intel Xeon-based servers are populated with multiple high-capacity storage drives.
There are three distinct server types in VDS-IS:
•
Content Delivery System Manager (CDSM)—CDE205
•
Service Engine (SE)—CDE205, CDE220, CDE250 or CDE280
•
Service Router (SR)—CDE205 or CDE220
Depending on your application, you may have multiple SEs and SRs. A network switch is employed to
link multiple servers together within a larger network.
There are six distinct server types in VDS-TV:
•
Management Server (CDSM & VVIM)—CDE110
•
TV Streamer—CDE220 (models 2C1, 2C2, 2S3) and CDE250 (models 2S5, 2S6, 2S8, 2S9, 2S10,
2S11)
•
TV Vault—CDE420 (model 4A) and CDE250 (2A4)
•
TV Cache Node—CDE420 (model 4G) and CDE250 (2G3)
•
Integrated Streamer Vault (ISV) or Playout Server—CDE220 (model 2D1)
•
TV Recorder—CDE460 (model 4R1)
Depending on your application, you may have multiple Streamers and Vaults. A network switch is
employed to link multiple servers together within a larger network.
Connecting Network Cables
Using the topology prescribed for the application, attach network cables to the network interfaces on the
CDEs at the maximum rated speed (see
Figure 1-8 on page 1-9 , Figure 1-9 on page 1-10 , Figure 1-10 on
page 1-11 , Figure 1-12 on page 1-13 , Figure 1-13 on page 1-14 ).
Note
If you are using a TenGigabit network interface, you must use the Intel Transceiver Twinax
cable.
