This topic describes how to cable the metadata server engine and
the RSA II adapter.
Context
Steps
- Perform the following steps to cable the hardware:
- For each of the two power cords, connect the appropriate end of the power
cord to a power supply and the opposite end to a properly wired and grounded
electrical outlet.
- Connect one end of the two Fibre Channel cables to the HBA ports located
in expansion slot 2, and connect the opposite end of each cable to the SAN
through a switch. See Figure 3. Two-node, two-switch, two-hub cabling example for
a cabling example.
- For redundancy, connect another Fibre Channel cable to the other HBA port
in expansion slot 2, and to the other switch (or zone). This is optional,
but recommended.
Note: The SAN File System user LUNs and SAN File
System metadata LUNs do not share the same ESS 2105 Host Adapter ports. User
LUNs should not be visible to the metadata servers in the SAN File System
cluster. Metadata server LUNs should not be visible to SAN File System clients.
- Connect one end of the Ethernet cable to the integrated 10/100/1000 Ethernet
port in the engine, and connect the opposite end to the Ethernet switch or
hub. The example in Figure 3. Two-node, two-switch, two-hub cabling example shows
a hub.
- An Advanced System Management (ASM) connector and USB cable are provided
with the RSA II adapter.
- Connect the USB cable to a USB port on the engine and the other end to
the RSA card.
- With an RJ-45 cable, connect one Ethernet connector on the RSA card to
the Ethernet switch or hub that is provided as shown in Figure 3. Two-node, two-switch, two-hub cabling example.
- Connect a ASM breakout cable (dongle) to the ASM connector on the RSA
II card in each of the engines present in the SAN FS cluster. Connect the
ASM breakout cable to the previous and next ASM breakout cables with RJ-45
cables. The first and last RJ-45 sockets in the chain must be terminated
with the terminators provided. See Figure 1. Connecting the RSA adapters together.
and Figure 2. RSA II adapter connectors.
- The 9-pin D-shell serial connector on the ASM connector is not used.

- Use cable clamps to secure the cables across the rear of the engine.
- Route the cables along the cable-management-arm channel, securing them
with cable straps.
Attention: Interconnect cables to the RS-485
connectors may be too short to route in the cable management arms. Use care
when sliding out an engine to avoid damaging a cable or connector.

- Secure the cable-restraint bracket to the slide rail, if not already done.
Route the power and network cables through the cable-restraint bracket, allowing
slack in all cables to avoid tension.
- For the master console, perform the following steps to cable the
hardware:
- Connect one Ethernet adapter port to the internet by way of the corporate
firewall.
- Connect the other Ethernet adapter port to the customer's intranet. This
network includes the RSA II adapters, Metadata server, and SAN File System
clients. The example Figure 3. Two-node, two-switch, two-hub cabling example shows
an Ethernet hub.
- Attach the keyboard, display, and mouse to the KVM connectors on the master
console.
